Some history first, I had oil leaks in almost every top part of the engine. I changed, the cam cover gasket, cam oil seals and I put instant gasket on the cover edges for better sealing. That was sufficient for a while a month or so...Then, after I push the car a little bit more than usual above 4k rpm, it started leaking again. Another clue might be that the leak started after I change oil and oil filter, however I can't figure it out how those might connect.
So far, I've checked how much is the engine blowby. I checked all the solenoids for the PCV and breather valves. All of them look fine, also the engine doesn't burn oil. Soon I'm gonna do a compression test for extra evidence.
Ideally I would like to find what exactly is causing this leak before I change anything again.
Does anyone have any clue on what might be wrong here?
