Estonian Ascona C Irmscher 88'

Recommended Posts

Hello everyone. I've found this board while looking for information on Ascona's in general and more specifically Irmschers. I'm actually a total Mercedes guy but this car kind of found me itself.

[img width=800 height=800]http://www.upload.ee/image/5169843/11922942_10207185926828158_205735626_n.jpg

[img width=800 height=600]http://www.upload.ee/image/5169845/11950792_10207185932988312_1839945779_n.jpg

I've had it for a few days and I bought it for only one reason, quick search told me that they only made 1399 of these. Seems I've gotten myself a bit of rare Opel history here. How many of these are estimatedly survived?

What i know about this car... It's an original Irmscher, it has the correct seats and upholstery (with cigarette holes and tears), the original steering wheel. I imagine that electric mirrors and board computer might be more common extras on other Asconas/Cavaliers aswell. Sits on original wheels and i think the lowering springs are there from factory aswell. Oh yea, it has glass sunroof and very cool Sony speakers at the back. The car also has had a respray once, thats probably why it doesn't have black stripes.

Downsides. Having been  parked outside for years has made a mess, some rust on rear arches and spots here and there. Underside is worse, needs welding repairs. Exhaust also rattles, i hope it only needs proper fixing.  There are also some "modifications" made by previous owner which i now need to deal with. Engine vent for example is forced to work from the moment when key is turned, plus some wiring mess.

Front brakes (Delco) is my current worry, at least one caliper is stuck on sliders, I'm working on these first as they are the main obstacle for getting our local "MOT". I've already replaced rear brake pads and brake drums with all the springs inside but i think one of the pistons was also stuck there.

It does not start well when cold. It stutters and dies a couple of times but eventually starts. Idle is jumpy when cold, better when warm. Haven't had the time to get onto it yet. All i know is that the rubber hose from intake to air filter and AFM? is cracked, i tried cleaning the idle valve but this didn't help much. If anyone has an idea what to replace next (Coolant temp. sensor?) then I'm all open for help.

This is a quick overview of my new car. I start to like it the more I get to drive it but I cant enjoy something that doesn't work properly.

I hope it's ok to ask newbie questions when I stumble upon some problems. Also any useful info on these is very welcome. Anything at all, my knowledge about Opels/Vauxhalls is basically unexistant :D

Cheers

Let's take a closer look to this thing then.

It seems that this board is pretty much UK "based". Well I've had the chance to experience your climate for a few months. 1/2 of the year it's similar to ours, i mean the spring and summer part. Not sure about your winters but i take a wild guess that snow, ice and -25 Celsius at winters does not necessarily happen too often. It does here, and the worst thing is that salt is being used to melt ice. Add it to temperature changes with quite an amplitude (-30C is no wonder, and neither is +30C at summers), some gravel roads and this happens. The same problem haunts both of my Merc's, this Opel could be considered quite ok... for Estonian Opel standards :D

Onto the interior, I had this Mercedes headunit laying around, it has different connectors to my Daily W124 so i popped it into Irmscher. I know that purists might puke but at least the display illumination suits. You can also see the original Irmscher steering wheel , ideally the leather would need replacing as it's cracked from sun but let's see what te future brings.

The speakers I was telling about in my first post. No idea if they have been fitted from factory but again, to my eye they are spot on! Both work and considering it's a 20+ years old stereo system, they sounded amazing.

[img width=720 height=960]http://www.upload.ee/image/5175939/11940189_10207206669586714_117046745_n.jpg

Do Asconas/Cavaliers have dash speakers?

Seats... dirty and have holes in them, but at least they are OEM.

Engine compartment, those who have eagle's vision or like carrots, might spot that some plastic parts have been used as a dessert. I blame rats.

One of the things that have bite holes in it is the cover for ignition. Possible cause for bad cold start? I bet some humidity finds a way in from there.

Alright, I've had some success with this thing. It's got our local MOT/TUV, also insured, so it's now fully street legal.

To get it legal I had to rebuild the brake system almost completely, some copper piping and front discs  with hoses are only things left from past. Brakes are now ok. While at all this I had to replace a wishbone joint thingy at the front, the one that requires drilling out old rivets.

Also changed the spark plugs, made a big difference, starts ok now. But something else is now wrong. It does not want to rev properly when accelerating. Kind of hesitating when WOT. I need to fix this first, has anyone got an idea what to check first?

The problem with engine fan is still here, I've changed all 3 thermo sensors/switches in cooling system. Connected fan to the switch on the radiator but it didn't work, went boiling. OK then replaced the thermostate, still nothing. So the fan remains in  "always on" setting. Maybe the brand new switch is faulty, maybe theres something else, anyways I've got an appointment with an electrician to work it out. Aswell as getting rid of old aftermarket alarm system.

Next problem is catalytic converter (cat). I did some welding underneath and removed the exhaust. Cat has a big lump in it that is one certain source of bad noises. Something else rattles in the handbrake area, stops when grabbing the lever.

Fuel gauge wasn't supposed to work, earth wire has rotted away from tank, still need to fix that somehow. Any ideas? Does the earth need to come from tank or is it ok to weld the dam wire to the underside? Anyways, I need to get my dash working first.

Thats all I can remember for now. Would like to enjoy it more, it's fun to drive but I cant do it with a car that doesn't work properly.

have you changed the flexi pipe between the air box and inlet manifold? seems to have silver tape on it in your picture of engine. That could cause all sorts of problems as you will have un metered air entering the manifold. Usually, if the pipe is split, when you rev hard, the engine moves slightly and the split opens causing the engine to misfire..

How long has the car been stood idle? You may have rust / dirt in the fuel tank clogging the inline filter. The fuel pick up in the tank also has a filter attached which could be blocked.

Fuel gauge earth wire has to connect to the sender on the tank, if you connect it to any other metal point on the car, the gauge will read full all the time.

Flexi pipe is definately F'd. Will look into it asap. (EDIT: Chris, your diagnose was probably correct. I added some more tape and it did improve things back as they were before. Starting to look for another pipe)

Good info on the fuel gauge, very much appreciated!

Another thing i remembered just now. I could really use a diagram or something to understand whats what in my fuse box.

If I remember to do so later on I'll take a photo of the diagram on the fuse box cover from my car.

Electrician had an infrared thermometer, this allowed us to follow warm coolant as thermostate opened at about 95C. The radiator went hot almost entirely, except the fan switch. It was around 70C but the coolant already boiled. Now we either didn't get the correct reading or there is something wrong with the radiator. I also need to try and test the new replacement switch, cheap aftermarket part, could be defected. I see the logic and these are my next steps. Autumn has arrived and its getting cold, takes a bit planning now to work on cars. I don't have a heated garage unfortunately :(

I mentioned the alarmsystem, he had a look and it took him only a few minutes to have it thrown out. Im going to start cutting out wiring sometime aswell, chance to take a minute and follow wires while trying to understand some logic. Im very unskilled what comes to electricity, but I would very much like to have some confidence with it.

Haven't found replacement for dash clocks yet. Were there digi-dashes on Asconas/Cavaliers from factory?

Digidashes come in Astra GTE 16v or Kadett GSi 16v where you are! fairly easy wiring job to put them in. if you buy one make sure you get the plugs with it, and most importantly the transducer which screws into the gearbox in place of the speedo cable.

To extend Brett's reply - there was never a factory digidash for teh mk2 - however there was an early "fuel computer option" and some dealers did install and fit dashes to cavalier stock if a sale depended on it. At least one GM management car we knew of had a digidash from dealership.

Hello again, since I didn't find a buyer for the car, I'm going to try and repair it completely. It will be a slow process with the intention of learning, DIY and anger management :D . If there is any interest I could keep updating this thread.

Hello, time has passed but i thought I'd give a little update to this thread here.

As one might notice, Estonian winters have pretty much destroyed the body shell. I had no practical experience with sheet metal before this project, slowly I'm beginning to learn now. I know the patches don't look too well finished, but this is the limit of mi skills at the moment. The struggle is real, limited set of tools and time makes it sometimes difficult to even find motivation. Maybe next year I have it all patched up. :)

Looks good, are you gas-less welding (which is harder to get a good bead)?

Have a look my Gregs LX thread at the chore of welding that up if you need some motivation :rolleyes:  We also rolled the chassis to weld on new chassis legs on the rear.  Mine is a bit messy in places but its not going to fall apart.

Eyes Paul.....use them.  Its has holes where they shouldn't be :rolleyes:

It looks shot blasted (or painstakingly rust wheeled off)....and its come up well.  A few plates and all its good to go.

I'm using regular MIG, with CO2 mix. Tall beads speak of my inexperience. Sometimes it's a pain to weld to the old metal that just melts away. 

First step was blasting the thing with glass particles. But that only took off the rust, it just bounced off the rubbery material that was used to cover the underside of the car. That I have removed using wire wheel on an angle grinder, alot of time has gone into this and im not even finished, 3 wheel arches still to go. 

Actually I was wrong, the first step was to finish off someones rotisserie project, this was used for blasting aswell. Saved alot of time and money. 

Some more pictures:

Welding is tricky on these cars, the rusty thin material is the problem so I wouldn't worry.  Every mm of wire put into the chassis is new matel.....if its a bit proud grind it back.  I took the worst off underneath then painted, seam sealered amd painted it again (I think).

That chassis leg at the pivot point looks a tad light on material, are you patching it up or replacing it?

That needs a replacement part. Other side might be repairable, but the curvatures there are difficult to reproduce from sheet metal, for me atleast. Some curved multi-contour parts at the front of the floor taught that to me. Replacement part is 150 euros i think.  

Also discovered that the sunroof's front edge side of roof is rotten. Weird , im definetly going to inspect the sunroof closely as its already off the car. Any advices?

Also, are there any pictures of inner sills on a factory car? I have a feeling that they should be spotwelded to outer sill, would be happy to be sure. Some kind of repair manual maybe has this kind of information. 

Could anything be read from it's VIN?

    • Looking good. You can never have enough protection on the underneath. As the last task before it gets turned back get wax into all the cavities, drill holes into those that don't already have them with plastic plugs to seal them again. If you are putting power steering in don't forget to reinforce that area
    • Painted and covered with stone protection. Im going to add another layer of paint on top of it, that is when im done sanding the inside of the car, and painted that with primers. 
    • agreed those wheels do look poor without the centre caps on.
    • Just a very quick update - am having starting issues, which I think is ignition switch related, rather than a goosed starter or solenoid, as both seemed to work OK when removed, cleaned and re-tested. Anyway, I'm really busy with work at the moment and spending more time away from home than usual but hopefully I'll manage to get the issue sorted before it's 2019!   The reason I've posted up again is because there's been a rather significant cosmetic improvement:   Before     After!   I must admit, a set of SRi wheels without the centre caps is possibly one of the worst looking things in my opinion, so I was very glad that some very kind soul on here PM'd me with an offer of posting out a set of five to me! They weren't even interested in actual payment, either, rather just postage costs covering and a donation to an organisation close to their heart. I won't reveal the kind member, as I'd hate for them to be inundated with requests of free stuff from others! All joking aside, I never discussed whether I would or wouldn't give their name, hence the decision. I've got to say though, it's overwhelming the amount of support I've had from members on here in such a short amount of time. I'll be sure to keep you posted on progress in return but like I say, it may take a while. Anyway, there's been plenty of other Cavalier bits winging their way over from the UK in the past couple of months, so I can't wait to get stuck in. And I didn't just receive the centre caps from the generous donator but more of the other item some other time!
    • why do you think i bought the estate i couldn't fit my cave in the hatch
    • I know you lot down Haverfordwest are a bit backward but tents are cheap enough and taking a cave to sleep in seems a bit old fashioned 😂
    • The way the VBOA have handled this has been appalling. Newbody you're not alone in your feeling. I will say that neither options for billing were suitable for various reasons and to be fair the new venue looks good.
    • The chairman of Vboa isn't relayed to Billy Smart is he ???   Because this reminds me of a 3 ringed circus 🤣🤣🤣
    • Plot twist this has more drama then some TV soaps!!!   
    • The first I knew was an email at 21.40 that I read half an hour ago. Sounds as if it could have some potential from an initial read. This is it. Good Evening,   For the purpose of clarification, when the term “we” is used, it is to refer to the VBOA committee of the Chairman, Vice Chairman, Treasurer, Secretary and the Event organisation sub-committee. Please read this all the way to the end as there is quite a lot to digest.   Voting on the Billing Options The voting and feedback from the two Billing options has been received and of those clubs who responded there is an even split between Option 1 and Option 2, with further feedback from some that neither is tenable resulting in a desire to not show at all.   Outcome of the feedback/vote With the results in mind, and taking into account the feedback received from individuals both on social media and direct to this email address, we have deemed it vital to seek out an alternative venue that carries neutral allegiance. To some, this will be viewed as a non-democratic decision, but we feel that attending either Billing or Market Harborough would damage the VBOA and its associated clubs in such a way that recovery would be very difficult. The venue that we have visited, discussed with the management and decided upon is Sywell Aerodrome (http://sywellaerodrome.co.uk/, Hall Farm, Sywell, Northamptonshire, NN6 0BN). This venue has held several automotive events each year, with a prime example being the Sywell classic also known as props and pistons which would be the closest representation to the VBOA National Rally.   Goal of the VBOA Show The prime goal for this is to take all the good from Billing and Market Harborough and improve on the not so good (toilets being the most obvious one). We also want to try and bring the general public/car fanatics in, so an element of rebranding will be carried out to step on from the term rally implying a motorsport event to a motor show. The identity of the VBOA National Rally shall not be lost, merely built upon to take it to a new level   Venue/Show concept We are looking to hire the venue exclusively for our use for the 5th-7th July 2019, where we will use at least two of the hangers (one is a bar/band area and carpeted), and the other can be for the auto jumble/trade stands so as to protect from any inclement weather. We also intend to make use of the concrete pan for the arena/food vendors akin to previous years which seemed to achieve the festival vibe that has been mentioned. Furthermore we intend to make use of the taxi way to have a 0-60/drag activity, this could also be a part of the parade lap should the desire be there.   The attached maps are a high level first pass at how the show could be laid out and given the space available, you would get the same stand sizes and setup (camping on stands) you have enjoyed in previous years. The only exception to this may be that if electric hook-ups are needed for things like caravans, then this would be in a single location with a limited number of pitches available. The space available for the show between the Arena and the far fence, to the North East, (or even the little roadway in from the entrance) is comparable to the area we had at Market Harborough. We do not have a layout for stands as yet but this will be high on the list of things to do and this will come out in time. Also attached is an image from the LAA show there which is focussed on aircraft, but it shows an aerial shot of just what is possible there. As this is an Aerodrome and not a purpose built camp/leisure facility, we will need to supply a myriad of things such as toilets/showers/PR/food vendors/entertainment/security and so on, if YOU or YOUR members can assist in the supply of this or anything else then please come forwards, this show will only be as good as we can all make it so the more involvement the merrier.   Hotel We understand that many of you and your members have already booked rooms at the hotel at Billing. Billing is approx. 10 Minutes away from Sywell, and we would look to put on a bus service of some sort for the weekend if the demand is high enough. Sywell have a 59 Room hotel on site, they have fixed their prices at £79/Night with breakfast at £8.50/Person. As they only have 59 Rooms, we suggest you book sooner rather than later, also do this direct with them and NOT Booking.com (http://www.aviatorhotel.co.uk/contact.php or 01604 642111)   Entry costs Now, the costs (some of these will be subject to change) Day entry for VBOA members (1 car + 4 people) will be no more than £10/day and working on a weekend entry pass too. Day Entry for General Public (1 car + 4 people) £15/Day Camping would be sold as a Friday-Monday (1 car + 4 people) at approx. £45 Additional car costs will be considered and information will be released but will be favourable. We are looking at options of early bird pricing and also giving 1 weekend camping pass per club as we used to have at Billing. This booking process would be using a dedicated booking agent that links directly to the VBOA.   Support As has been mentioned, there is and will be quite a lot to do to make any show at any venue work, even if we were back at a purpose built site for this type of thing, so we need your help. Helping does not mean you or your members are stuck with a job/task for life, it means that you have helped to make the show as good as can be. I have seen a sign in my local rugby club that says “before you complain, have you volunteered to help?”, I think this is a very valid and wholesome approach to anything like this.   There is of course much more to plan, prepare and do prior to the show and this is only the start of all the information that will come out, but it is everything we know at this present time.   Kind Regards   Stuart Lindborg Vice Chairman – On behalf of the VBOA Committee and Event Sub-Committee.
