Excessive crank case pressure

[decwhiteoak95]

Hi guys, I bought a glanza a month or so ago which was running on 2/3 cylinders and had excessive crank case pressure, oil coming out of filler cap, I presumed that this was piston ring or ring land failure but when we removed the head, the gasket had a big bit missing between cylinder 3 and 4, just Curious of this could case the crank case pressure some how? Cheers

Since your halfway there I would remove the pistons and check them as its a common problem
