Thread: another BBC valve adjustment question with picture

Tweet

It has been my experience that twisting the pushrod to take the slack out of the system will end up with valves off their seats from excessive preload.
Also, you don't want the intake and exhaust tappets to be even with each other necessarily. You want each tappet to be on the heel of the cam lobe when doing the adjusting. Both the intake and exhaust tappets cannot be on the heel of the cam lobe at the same time. Please read through this tutorial....

While there are at least 3 different methods to lash valves on a motor, this procedure is bulletproof if you just follow the instructions given. Many fellows have come back later and thanked me for writing this.
