I'm sure the valves and piston( one or more) touched after the dowl was broken while being turned over by hand.I felt the resistance but didn't know what was going on .Hell I just noticed that the valves wern't moving .The distrib was installed as a visual indicator to see if the cam was moving. The heads pistons have not changed . Just polished the crank(still std.) ,new bearings,honed the cylinders and new second and third rings.New camshaft lifters pushrods and timing set.The back of the cam gear was gouged by the broken pin.How long is the dowl in the shaft? what is better than a carbide bit?I'm just at 1/4" penatration.
I called Comp Cams for assistance I was told that the dowl is just there for indexing and the bolt tension was what turned everything.The tech was going to get a gear set and check out the pin and hole sizedifferences..Haven't heard back yet.
