Ive never had valve seals go on me before but I was just trying to figure out how much oil can get in the cylinders if they are gone? Right now I am trying to diagnose a problem I am having with my motor.

The motor is a sleeved block, wiseco pistons getting 220psi at WOT on all 4 cylinders.

The head however is stock and has been sitting a while, my assumption is the valve seals have dried up since the problem only persists when it is in cold start and in normal operating temperature it stops burning the oil.

I just took off the head now to put my built one on and the head is black as day on the exhaust ports in each combustion chamber. The tops of my pistons also have a bit of browning on them as well and the motor has only been run about 15min.

So im just trying to figure out if its anything else or stick with my orignal diagnostic of dried out valve seals
