I can't believe that I've not posted for almost 2 years. I finished the car (almost) in the summer of 2018. It runs and drives pretty much flawlessly. Now with some extended time at home, I've decided to address some minor issues. The main thing is excessive oil leaks. It absolutely leaves a few black spots every time I park it. I know the rear main seal leaks (like all 948's) but it is also leaking around the valve cover and and engine side covers.
Any hints and tips for the best way to seal these? The valve cover has a cork gasket and was sealed with Hylomar blue. I'm surprised it leaked, and it only seems to be in one place. Hopefully cleaning and re-sealing will address that.
The side covers leaked a lot. On these I used rubber gaskets with no sealant, clearly that didn't work. They also leaked around the bolt hole where there was no gasket, just a metal washer.
Hopefully addressing both of those will help a lot. I'm then thinking about a catch-can of some sort for the oil that leaks from the rear main. Anyone have experience in making one of these? I remember seeing something a while ago, may it was posted here on BCF.
