Mahle FRM Friendly pistons, get it down to 9:1 (available in different applications)

Or use a thicker head gasket

I just got slightly thicker o rings for the dip stick from my local motor spares. 10p each. Job done

Although as others have said, it won't stop hundreds of psi pushing at it if your cylinders are blowing into the crankcase. If your compression and leakdown tests are all good, then go for catch can and/or vent filters. As stated, crankcase pressure should be negative.

Wayners

Not the best shot, but Toda, and ASM ( I think) use a spring like you see on some exhaust manifolds to hold it down.

I've been looking at these in the future when I desire more boost. I'm sure with a good breather set up you shouldn't have any issues though. You just need to relieve some of that pressure more effectively. T1 Race developments do a great kit. My fabricator is making one for my turbo build using 4 vent locations on the Valve cover.
