Corrado G60 Is it worth Saving? (Over Just getting a new Corrado)

Recommended Posts

Hello everyone, so a few of you will have probable noticed my last few posts relating to trying to buy a Corrado, with some unfortuantely issues with thsoe plans thrown in there.

Now my Corrado knowledge and issues all stem from trying to save my dad's old Corrado G60 (1992) which was parked up for nearly 15 Years, as you can imagine after 15 years sitting around,  did not leave the car in a great way. I decided one day that the car had spent long enough sitting around, so decided to go about what I could to get the car back on the road...Which is what i managed to do. As I got the car MOT'd and running

All in all the car has had:

- New Brake Master and Slave Cylinder (Clutch Pedal was stuck to the ground)
- New Ignition Switch (and Wire to Starter)
- Replacement ECU (Old one had been fried, and had a no spark issue, but is currently off being repaired by a trusted friend)
- General Service items, Dics, Pads, Oil. Filters, etc...
- New Fuel Pump (Old one had siezed)
- New Brake Lines all around
- New Cambelt (Garage did that when it had an MOT)

However the car never ran right, I haven't spent too much on the project really, and have learnt a lot of it because of the car, it was around this point though i realised that the G Ladder had been replaced with an Eaton M45, the issue I see with this is that the throttle body has been moved, which ofcourse meant that the 1mx3.2mm Vacuum Line wont work at all. So that's why I have sent off the old ECU to be repaired as I noticed when i teared it down to inspect the damage that there was damage to some of the diodes (the no spark issue), aswell as it had been chipped. My hope with getting this repaired being that maybe it was mapped to the longer Vacuum line from the ECU to the now moved Throttle Body.

Currently the current issues as I can think of them amount to:

- Car runs rough, really rough. I managed to get the car home from the Garage but it wasnt happy, and pops and bangs were frequent by the time I got it home
- Body work is generally good, but aerial has rust and a few blemishes on the bodywork
- Other age related issues, stereo, and a few electrical niggles, windows, and indicators work when they want to.
- Braking system is capput. I think it's down to the ABS Computer, feels like brakes are unpowered, and only braking at the front.
- Windscreen bond is getting weak, and i noticed a drip or two make their way through, not great.

All in all as I said i dont think any of this has been in vain as I have learnt a lot about cars from this project, however im at the stage where I dont know what to do. The car needs someone more knowledgable than me for any of the jobs going forward I think, I will be testing the car with the Original Chipped ECU when i get it back just to see if it helps the car run less rough. But it feels there are so many issues, that it might be worth calling it quits and looking at getting another Corrado...One that wasnt sat under a tree for 15 years.

At some point ill get around to getting some video's or photos of it which will probably put it into perspective the situation a bit better. I just have many issues I dont know how to solve that im not sure what would be best. I would imagine dropping some money into the car at a garage would leave me with a worse car than just purchasing one if something comes up...As you can tell im pretty conflicted and confused about what to do so I thought id turn to the forums and see what the community thinks.

Cheers Fellas

Electrical stuff can all be fixed - usually just a bad earth or short/broken wire. Just takes time and patience.

The brakes sound like the rear callipers have seized, which is a common problem, and possibly your servo assist is not working, usually and air leak in the vacuum system.

I guess it comes down to how much your budget for a new car is and if you have any emotional attachment to this one - overall it just sounds like any project that has been left sitting for a while. Any other Corrado will probably still need a lot of things sorting unless you pay top dollar.

G60s are now becoming very rare and it would be shame to let one go to the great scrapyard in the sky.

Yep. After spending a few days sorting a few jobs around the car (a lot of electrical stuff I don't mind dealing with, as most issues that were already there I have sorted) 

 

Just called up a local specialist, and their resident Corrado Mechanic is actually back next month. They'd be willing to give the car a look over, and I'm very tempted to say that might be the direction to go in.

 

All in all I'm open to any suggestions, but I am quite heavily leaning towards saving the car (already half way there as it is at the moment)

The windscreen issue may be worse than feared. They often rot underneath the seal so it needs cutting out and replacing with new metal. Factor in paint and it's quite a big/expensive job. A lot of your issues with running are likely to be due to the Eaton charger. I don't have any experience with them so can't say too much, though its likely to need mapping to suit, if that's even possible with stock management. The fact that it passed the brake load test at MOT is concerning judging by what you've said about them too. Rear calipers are known to seize, but you mention ABS - is the light on? (Should have been another red flag at MOT), but it could be an indication of any of the ABS components being duff. Best case a wheel speed sensor, worst case pump.

What you need is someone who has experience with the G charged engines - a lot of places over here won't deal with them any more. Or another G60 owner who could help out. I think there are a few common issues that cuase rough running, and once they are sorted should be ok - the guts of the engine are the basic 8v block design after all, and they are practically bulletproof.

The brake issues started after the MOT, as did the ABS Light. As once the car was up, and running (and driving) I dropped it down for an MOT.

 

I've been told there is an ABS Delete that might be worth looking into.

Popping and banging, after dark run the engine and use a garden hand spray bottle to mist water over the ignition leads - look for sparks jumping from lead to lead (cross-firing) or lead to engine block

New HT Leads, however both old and new have the same running issues. 

 

I reckon I've got some G60 Issues and Non Stock Corrado Issues.

 

Will have the car up and running as soon as I get the ECU Back

What was the problem with the ecu, injectors staying open?

Don't assume new parts (made in China) can't be bad.

No Spark. Fried Diodes internally. I reckon at some point the car had been started with bad grounds and fried the ECU.

 

It is currently being repaired at the moment. The replacement is a new old stock G60 ECU. However I would prefer to use the ECU that is mapped for the car.

These have chips in a socket? Why not just swap the chips?

I'd rather have two working ECUs so I sent both off to a friend of mine so he can use the working one as as a visual reference.

 

I'll have both back soon.

your running issues are probably down to various leaks on the boost system and other vacuum lines and plus if the car has not run for 15 years

the fuel filter / lines/ injectors blocked .

to be quite honest it possibly is a multitude of things.

who fitted the eaton charger ???

Dont let another corrado go to the scrap yard in the sky!!!

Fuel lines have all been checked over and replaced. 

I found a video of when I first managed to get the car running, which I'll try to post in a bit.

 

The Eaton was fitted by a company over in summerset I believe, they've since gone bust. So no use contacting them at all.

You need to try and run it with a good evu first then I’d be tempted to let JMR have a look. He seems to be the 4 pot/G60 man.

I know it's messy. But i went through organised and labeled a few of the obvious issues. Such as loose vacuum lines etc.. (Please remember that I am without an ECU, not that I really have a vacuum line to currently stretch to it)

Most of what has been done is undocumented from well in 15 Years ago. Will also try to get it running to the best of my ability when the ECUs Arrive back.
