Oil Leak from Lower Exhaust Studs

by Steve Morrow in 912 / 914 Technical Questions 5 years ago

I have oil leaking, very small amount more like a seep, from the lower exhaust studs on two cylinders. Any ideas? I am certain the studs are the source.

Good picture.

This is seems to 4 possible causes.

1. Engine stored for long times in downward position and after that when started some oil leak.

2. Worn oil rings may causes oil leakage

3.valve seals on inlet side only may be leaking.

4. Some of engine head with specific no have changed the parts .

Details in video.
