Valve To Piston Calculator

valve to piston clearance needs to be checked during the overlap period of the camshaft...where it exhaust valve is closing the intake is opening...that is where the pistons and valves are their closest..

you can remove no. 1 intake and exhaust springs..and but light valve checking springs on number 1 cylinder...set up a dial dictator on the intake valve and turn engine over by hand ..and check valve to piston clearance every 2 degrees thru the cam over lap period....repeat the same on the exhaust
