have had an oil leak running down back of engine. Couldn’t quite tell if was intake manifold or valve cover, decided to pull apart and do all the gaskets. Found some oil sludge buildup in valley. Looks like I’ve got some cleaning to do, and some hardware to replace.
How much sludge is too much? How far would you go with cleaning/maintenance if you opened the lid and saw this?
