Rebuilding a Blown Engine - Part 3

Once the head was rebuilt and torqued down to the engine, we could assemble the valve gear. Both of the cams were laid in the engine without bearings or cam followers, and the cam chain was draped over them and held close together with wire.


Once the chains were held in place, we inserted and pressed together a master link, using a feeler gauge to get the correct lateral clearance.


Once the chain was finished, we rotated the cams to their approximate final position, assembled the cam bearing caps, and started timing the cams. There are marks on the right side bearing caps which should align with marks on both cams when the crankshaft is at left TDC.

Almost...

Almost.....
After a few hours of swearing, caffeine, and torn knuckles, we succeeded in correctly timing the cams. Once we bolted it all together, installed the cam chain tensioner, set the clearance in the cam followers, and bolted on the covers, it was time to unite the engine with the rolling chassis
