12+ Diagram 5.3 Timing Marks. Cam gear mark should be at 6oclock and crank gear mark should be at 12oclock while #1 piston is at tdc. So it is best to turn the engine to the appropriate marks to take the timing chain down and reassemble the timing chain back on and then crank the engine once, which means.

I am having trouble finding a diagram or book that references the proper 0degree mark on timing marks that look. Cam gear mark should be at 6oclock and crank gear mark should be at 12oclock while #1 piston is at tdc. There’s an adjustable plate that should be set while the head is off!
