I bought my '93 Corrado VR6 in May 2017 - with very little knowledge of the car and the engine.
After speaking to friends who have an interest in VW cars, I found out that the engine is not an original Corrado VR6 engine, it was out of a MK3 Golf. The engine bay has also been partially smoothed (badly) so there are things that are missing from the bay. I say badly because the air filter was behind the engine and above the exhaust manifolds.
Our assumption was that a previous owner had tried to supercharge the car, hence the bay smoothing and some pipes being in a strange places. They blew the original 2.9L engine and replaced it with an 2.8L out of the Golf VR6. This didn't particularly bother me because it was drivable. However, I had persistent over heating issues to the point where I would get coolant temperature of 120 and oil temperature of 140. After changing the thermostat and trying coolant additives it still didn't make a difference.I've had it block tested and its definitely head gasket failure.
I took it off the road and put it into storage while I decided what to do with it.
Current Problems with the VR6
Current engine head gasket failure
No heater matrix
Power steering bar is covering the oil filter housing
Oil cooler failure
Water pump failure as a result of head gasket failure
Multiple coolant hose rupture due to head gasket failure
Bonnet cable snapped
Hazard light switch blows the indicator relay
Rear fog light out
Most of the sensors don't work
Cables like a rats nest behind the dash
Speakers aren't wired in
Radiator full of rust
Good Things about the VR6
It's a good colour
The sunroof doesn't leak
It sounds amazing
It's a Corrado
It's fully polybushed
I have a 2.9L engine ready to go in now, the next post will be more about.
If anyone has advice or ideas I would love to hear them.
