Are these worthless, or can they be decent for a daily driver? I noticed when I rebuilt the turbo on my Lancer that the head must be of Chinese origin. Do the bolts for the intake go into the oil galley like they do on the Chrysler made heads? I think that's where I'm losing the oil from on my Lancer. It's burning it on top of the exhaust manifold around #1 and #2. The plugs are clean, but the oil seems to be coming out with some pressure and there's a very decent amount of it coming out from up there. I've never dealt with a Chinese head before so I'm not sure how to go about this. If it were a Chrysler head, I would be certain that my problem is someone not putting enough sealant on those bolt holes.
