[QUOTE="Scotty B, post: 12019516, member: 83895"] Not normal. Hard to tell from the video but, sounds like metal to metal. A friend of mines car had a similair noise. We thought it was a lifter bleeding down. pulled the cam covers and all the lifters were solid. chain tensioners were also tight. Dropped the pan and checked all the rod bearings (had to lower the K member, PITA). they were fine. finally, found #5 piston was loose in the bore. It had scuffed and started slapping. Not saying thats what going on with yours. Just illustating how we tracked it down. It doesnt sound like an exhaust leak in the video. I would make sure tho before going to that extreme. You could also remove the blower belt and start it up. This will rule out any supercharger issues if the noise is still there. GL [/QUOTE]
