My symtoms that lead me to the test were: 1. oil blowing out of the breather on my valve cover, only a breather because a catch can plumbed in any manor would cause severe exhaust smoke 2. general oil leak/s all over motor, and burning oil. (took 5 quarts to drive 3 hours home) and 3. Loss of power, (no sht right).

My readings were (dry)

1:75
2:80
3:85
4:90

I then followed that up with a small amount of oil in each cylinder (wet)

1:80
2:90
3:100
4:120

I can't decide if its a head gasket, piston rings, valve seals, or combination of those. mainly due to the odd patterns that emerged. give a zilvia noob some love.

We had the EXACT same problem. We did the head gasket, put it all back together, and NOTHING. just cranked. Pulled it all apart, piston rings where fucked.
