pulled head and this is what i found.opinions needed please...
take a light and carefully look around the edge of the piston. you maybe able to see some damage. With all that oil in the cylinder the rings are either busted or the piston is. Other things could be involved too but now that you went this far i would pull the pan and pop the piston out.
what throws me off with this is the lack of noise you say the motor didnt have. Typically when u have a busted ring landing like the picture on the previous page shows, you can hear it. Try turning the motor by hand to bring the piston all the way to the bottom then all the way back up. Then once again rotate the motor so the piston is at the bottom. See if any oil finds its way passed the piston rings.
Did not check this.We did pressureize the cylinder with the rockers off and noticed that there was air coming from the oil tube but also checked other cylinders with good compression and they did the same thing so did not take this as meaning anything.I should of bought a leakdown tester but was hoping to see evidence with the head removed.It appears that i made a mistake here.
You state above that the cylinder in question made 70 psi, where the others made 190 psi. That's enough information to be considered a pressure/leakdown test. Potato, Patato, it was enough of a leak down/pressure test to call it one.
You have a very obvious ringland problem w/ that cylinder.
Is it just me or the exhaust valve looks burnt?
It seem like a piston ring/landing problem. It's acting and looks just like mine did when I blew off my top piston landing. Yet it still looked perfect from the top. The piston ring was holding the piston together.
Any metal in the oil?
Here is mine.

From what i see in the pictures i'n starting to think its possible you have pasted rings and the pcv system is adding enough oil to make the cylinder look this bad. Pasted rings can fool you into thinking something is wrong.

Verdad Gallardo Excuse my ignorance but what are pasted rings? All my friends here also told be that i should hear an issue if the ringland was bad but we did not hear a tick or anything. Thanks for all the replys fellas.
Carbon build up can cause the rings to stick or paste to the piston. They stop moving and then loose contact with the cylinder. Happens in high mileage engines depending on what oil you use etc. Not saying that it but it sure looks like it.
