A friend of mine has just bought a 90 Manual TT off fleabay as a project, the car is imaculate but does not run right or idle. It sounds like a huge blow from the drivers side downpipe but i was under the car and tightened everything up and cannot find an exhaust problem. the car sounds like the exhaust is not attached its that loud. Im wondering could it be a gasket problem between the Plenum and the heads. The car holds perfect temp and oil pressure and no mechanical knocks or taps just this blowing sound. The engine has been freshly rebuilt with new turbos but tbh a poor job of refitting the engine found loads of connectors broken or unplugged including one at the back middle of the engine which i think is the det sensor, Would anyone have any idea's??

maybe a crack in the exhaust manifold?

Update:

 

Managed to get the drivers side exhaust manifold off without raising the engine to find the back of the exhaust manifold gasket was missing, Blew through a gooden. So it can be done without lifting the engine.

you must have very small hands lol

completely the opposite fella, minus a knuckle or two though lol

and skin i bet lol

I will be replacing both of my manifolds (hopefully) in the very near future.

 

Have you got any hints/tips to do this with the engine in situ?

Well i had the turbo and starter off and just took my time chap
