Hi all,

I have posted several times on this forum regarding my engine and transmission rebuild.

Thanks to Ian Karr's video on valve train geometry it really helped me visualize what exactly needed to be done in order to get everything lined up and adjusted properly.
Haven't done it yea, but the engine is dropped and ready to tackle this project.

My big concern is my inability to stop this oil leak which is present on both sides on the engine.

I bought the extra thick cork valve cover gaskets from 914 rubber.

Based on the images could anyone deduce the source of the problem and a once and for all remedy?

Same with the push rod tubes. Are there any oil leak proof pushrod tubes and seals that can keep the oil leaks from sneaking back?

The engine rebuild probably has 20 miles on it as due to the oil leaks and a terrible valve train geometry job done by a local volkswagen shop. These things prompted me to drop the motor and redo things.

Oil pressure sensor leak resolved. Oil cooler seals are good and no leaks.

The oil you see in the images, and some drips from the pushrod tubes, which could be from above and also on the heat exchangers streaks of oil coming down them from the engine.

It also have noticed oil in the exhaust to muffler gaskets. Is this normal, if not what would that cause and remedy be?

Thanks a bunch, I know I have a lot of questions but I would really prefer once and for all to address these issues.

Thanks,

Gary

Seeing as your heads are very clean and dry other than around the valve cover, it pretty much has to be coming from there. There isn't any other oil source that far out on the engine. The top picture shows the valve cover upside down from previous use, you can see the paint scraped away where the bale drags across, the scrape would be downwards, not up towards the intake. You can tighten the bales by bending the ends in a bit if they don't feel like their really snapping into place. Once the valve covers are on, I take a screwdriver and pry the cover down slightly to make sure the edge isn't hung up on the sealing surface. I love the smell of hot oil keeping my heater boxes from rusting!
