[QUOTE="03BlownSnake, post: 4161141, member: 9689"] Ok.. so new development... I was adjusting all my rockers, so I decided to pull the plugs so it would be easier to turn the engine over. I came to cylinder 4 and the plug was filthy, COVERED IN OIL!!!! So, ofcourse Im like, ok, time to really tear it down. I took the head off and found normal looking oil deposits on all the pistons, so ok, no visuals indicating anything major. I removed the piston and only found the piston rings where positioned incorrectly, both ends/gaps where facing almost inline with each other. That shoudn't be right? Anyways, the rings looked ok, no cracks, so I reinserted the piston and torqued it back down. I was carefully looking at my heads and found something wrong. The valve seals where not where they should be. they where "free floating" on the valve stem. Now, I know that cant be right. What can cause something like that? All my springs seemed to be ok. The oil on my plug really worries me though. The underneath of the actuall valve had alot of carbon/oil build up. Has to be due to the valve seals possibly not installed correctly I guess... Anyone ever seen this before? [/QUOTE]
