@95Zenki: Your list is exactly my idea of things to do. Will take the engine out this weekend.

@Chris: Yep, sounds like it haha. New rings are gonna be in when stuff is apart, so should do the job icw new headgasket.

Update:

Did another compression test to rule out a faulty gauge and this time the numbers were all around 90 psi... checked my neighbours fresly rebuild engine with known 150psi comp and the gauge read another 93 psi....
Not the best measurements but a good indication bottom end seems to be ok.

Took the engine apart and found out

- Oil + coolant on all 4 cilinders/exhaust ports
- Headgasket looks fine
- Pistons look fine, no damage
- Rings are there (feeler-tested around piston)
- Walls are perfect

I think i lifted my head?!

What else could pour oil and coolant into ALL cilinders?

Ideas are appreciated guys

Daniel
