Oil leaks

Share this page

I see your problem right away you should have painted it all black . Not really it all looks great nice job. Bolts might work with a copper washer and sealant on threads. As for the valve cover others are right on seal to cover not head. The alum cover is a good look I have one on my TR 6 and yes all flat so cork not that great as a seal. I cleaned my cover after fight with cork I then put a high temp sealant on cover no cork and let set over night ( large bead of sealant ) It acted as a permeant seal and have adj. valves several times over the years and still never a drop remember never over tighten it just bends cover. I have just pulled my trans. to seal all leaks. It was the front seal of the trans not rear main As I replaced starter I replaced gear on flywheel also still clean and dry rear main. one for the team me. Over the years I have worked on many leaks some do to my first try others do to time running my car. My timing chain cover leaked for years just a drip or two I thought that ran all to the back of the motor so looked like every thing leaked. Two years ago I did the rear differential a pain for sure but all still dry. C 19 may have you home so what left to do. Madflyer
 
Concerning valve cover to head leak.

The cork gasket where the leak shows is not in its channel, see how it sticks in under the cover.

In fact an easy fix we have all done.
 
It also indicates by the soft black stuff in the exhaust pipe at the manifold that it is maybe running rich. Look at the other end of the exhaust pipe also. It should be a nice tan color if all is well.
