Pulled valve covers... one side is burnt looking??? why?? *pic inside* my buddy has a JY LQ4 we picked up for a decent deal.... we have gotten around to pulling the valve covers off and one side looks burnt~ish everything is just darker in color on the one side.
Any ideas why this happens?
havent pulled the plugs or oil pan but the rockers and pushrods are all darker color????
any info helps..

The color difference is from the baffling on the top of the drivers side VC compared to the lack of baffling on the passenger side VC.

Never said that any valvetrain parts were replaced though.
the valve springs, retainers, pushrods, rockers all showed a darker shade on the one side.
Took the plugs out, they were all the same. (no melted, white, etc.)
pulled the heads off, all pistons and cchambers showed identical buildup.
I did notice however a weird pastey, tacky, almost grease like substance in a couple of the intake runners of the heads though (i never seen before). idk
last thing to do is pull the oil pan and do a visual of the rotating assembly.

With that said I guess I'd lean toward PVC....I can't think of anything else....I white pasty stuff I've read that from runnin to cool of a stat and the oil not getting hot enough...
Deff weird keep me posted. Good luck.
