Car Model/Spec: 306 GTI-6 trackday toy
I've got an issue with my gti where it keeps pushing up oil through the oil filler cap and via the screws that fasten the valve cover.
This has been an issue as long as i've owned the car so it's nothing new.
As far as i can tell there are no clogs in the crank breathing system.
Is this something that anyone has experienced and perhaps even know a solution to?

As in when you take the cap off it splurges out?!
Or just build up in the lip around the cap and around the recesses for the bolts?

Builds up on the lip while running. Never tried opening the cap with the engine running.

Try taking off the one way/check valve (black round thing on the pipes off the rocker cover) - sounds like that might be jammed/blocked.

Already checked unfortunately, no blockage there. Also had the rocker cover off and checked the oil mist trap (if that's what it is) without finding anything strange.

The problem was solved by a new oil filler cap a couple of months ago.. I love how I always think it's some really catastrophic issue but it's usually something silly like this time.
