I was doing a head gasket replacement job on my 96 Acura TL 3.2. I ran into a problem with the timing mark on the cam gear being 45 degrees off to the right of the right head. The crankshaft and the left head timing marks are at TDC.I have both heads off now. How do I get the right cam gear timing mark back to TDC while the valve springs and cam lobe is under tension?
