Timing and tensioner

Loosen your rocker arm rails then set your timing marks. After they are set tighten left or driverside rails. Turn your crankshaft to where number 4 cyl is at tdc and tighten the right or passenger side rails. Maje sure your lifters are completely down or you risk snaping the rails or worse. Dont. Turn your cams with tension on the lifters valves or rocker arms because if your not on your timing marks. And synced with the crank you will more then likely end up with a bent valve or believe it or not broken piston.. Remember #1 at tdc driver side lifters will be down #4 a tdc passenger side. Lifters will be down
