I hear that the 02S is pretty much a straight swap for a mk2 and as such, usually demand quite a high price.
As for the fuel tank, that will definitely not fit. The extra 15 litres are on the top of the tank as the Corrado boot floor comes higher up. I tried using one for a VR6 conversion once and the tank was so big, the fuel filler stopped about 10cm below the hole in the side of the car!
I need to get a replacement headliner but I like the original design so it means buying the fabric from Heritage andgetting it stuck on a glassfibre shell. It won't be cheap, hence it's on the back-burner !
Yeah, whatever, you do, don't use the original headliner, I've tried twice now with various glues etc, longest it's lasted is two years. The liner is just dissolving at this point and taking the glue with it.
Pretty sure the oil pressure light is coming up because the engine has shut down. It's not smart enough to shut down if there's low oil pressure. Oil, water temp and battery lights all come up if the engine stops and the key is still in the ignition position.
If the engine is shutting down after only a few minutes, it could be that it is coming off it's cold start cycle (where it adds more fuel in) and then the mixture isn't right to continue running.
Can you keep the engine running if you push the accelerator a little?
If so, see if you can take it somewhere to get the carb mixture set up.
No too bad, you need to sacrifice the green end cap (and sometimes some gearbox oil) to get at it, so get a new one before you start. But I've done it off a jack and popping a wheel off, maybe an hour max.
Unfortunately, you've now changed all the easy/cheap parts to change between your foot and the clutch. Did you pull the rod out as well? The end of it is the part that physically pushes the clutch in. Has the clutch always been like this, how long has he had it for? I've never heard of an oe clutch being heavy though failing (they usually slip), but then you've probably got one of the last mk2 golfs with the original and now 30 year old clutch in.
It would do if the oil has gummed up in the bearing and input shaft through minor use over the years. It would also allow you to examine the arm and ensure it articulates freely.
