Oil leak from exhaust manifold bolts?
Posted: Wed May 26, 2021 8:44 pm
New to the forum and haven't found a thread that would be talking about this. i have a 1995 460 turbo with B18FT engine and noticed a slight leak from the rear side of the engine. One on the timing belt side with the furthest bolt of the exhaust manifold and the other from the other side of the engine. what are the common oil leaks there and are there any oil channels behind the thread of the manifold? planning to remove the intake and both manifolds on one of the weekends asking just to prepare myself a bit and to know what to look for.
Turbo itself seems to be dry, so does the valve cover gasket. Car runs normally otherwise. The leaks are apparent on short rides, after long ones (30+km) the ground is usually dry. Also the crankase breather valve is obsolete from my inspection, planning to do the audi part mod alongside the leak repair.
Thanks in advance hoping a 460 question doesn't make anyone angry but it is a brother of 480 nevertheless
