Timing Chain Hitting Valve Cover
not really sure what the problem is, i was taking the valve cover off to check out my retainers, then noticed on the cover it was all scared up, looks like the valve cover sitting too close to the timing chain?

A loose cam wheel bolt will do catastrophic damage to the entire engine top and bottom. The entire engine suffers a major internal oil psi leak. Seen it first hand.

Are the VC grommets a snug fit? OEM? crappy grommets can allow the VC to sit back a bit.
It wont back out over time. But it will come out and destroy the engine entirely if it was not tightened properly. I would break the cam wheel bolt loose, then reset it with a torque wrench.

i bought new valve cover gasket and OEM grommets and spark plug seals, was going to replace when i did the valve adjustment, maybe they have just gone bad, ill run out and get the hex bolt socket and tq wrench and retorque. should i do these to the cams sprockets as well? or just idle gear? this is my first s2k so still learning here, i have had all b series motors lol, will the cams turn when torquing down? i appreciate it bill thank you

Bad valve cover seals will not cause this rubbing issue. Even without seals installed it's impossible to slide the valve cover back enough to have it hit the idler gear. Most likely somebody had it loose before you and turned it over, realized their mistake and tightened it up. I would still do as Bill suggested and loosen it and re-torque just to be on the safe side. The cams will not turn when torquing as that bolt is independent of the gear itself.
