Oem valve covers and coil pack cover. Is there some kinda adjustment? So weird. Valve covers in place and the bolt holes for the covet are like a 1/4" off. I can line up either side intake or exhaust but then the other side wont line up... any ideas wtf is going on?

I had that problem on my Honda. Not sure if it got heat warped or what. I ended up just slotting the holes.

Ended up placing the valve covers on without any bolts. Installing 4 corner bolts of the coil cover. Then hand tight the outter middle bolts on both valve covers. Remove coil cover then install all vc bolts and it all lined up. Weird cuz ive removed the valve covers several times and never had any issues with the coil cover lining up
