Re: Expansion tank overflowing - with oil!
Well, it's turned out to be the heat exchanger after all. I found a virtually new h/e off a 166 for just 80 euros, which included the coolant pipes. Which was nice. Especially since new ones were E222,34 in 2000.... My local main dealer have their own scrapyard, where the write-offs and old cars are dismantled. They have a HUGE stock of parts, engines, body parts (huh?), etc.
So i decided to fit this anyway (as I didn't want to run the engine to do Jimybob's test, although it's a clever trick), as I had heard from several people about h/es giving up, and my car has 217000 kms on the clock. And the car is running fine again! Quite a relief to see the pressure gauge going up to 4 bar again! Now I just have to find a way to get all the crap out of the cooling system... And get myself clean...
Only, now I have a spare head gasket and stretch bolts lying around, which i'd bought in my deeply depressed state monday morning when I was still certain that the worst had happened. I've been advised to fit this as a precaution, as "the head gasket is likely getting a bit tired after more than 200,000 kms". Any thoughts on this? I'm thinking why fix it if it ain't broke?
Finally, anybody like a GTA-engine for their 155? I saw about 7 of them lying around, new, complete with subframe, box, suspension struts, with just some smoke damage. Apparently there was a fire on the ship carrying new cars, and the cars were scrapped because of smoke and water damage. So I guess my next car will be 155 3.2V6 GTA! Has a nice ring to it, don't it?
