Project Mudslinger: Block Damage

Because we scuffed a rod bearing, Yates decided the best thing to do was replace all of them. This, of course, means rechecking all the tolerances against the crank just like it is a brand new assembly.

We probably could have gotten away with reinstalling the rings, but it's much simpler to replace them now, rather than later. Yates uses a standard tension set in ours because we are more concerned with engine longevity than squeezing every last drop of power out of it.

Before bolting on the head and degreeing in the crank, Yates confirms the number one cylinder is at TDC.

A single overhead cam engine is fairly easy to set the advance. After confirming the deck of the head is dead level, set an angle finder across the lobes (intake and exhaust angled up). Zero degrees of advance is when the angle finder is level. To advance the cam two degrees, simply rotate the cam until the angle finder reads two degrees.

Here's our new engine, all belted up and just about ready to go. Johnson's new pulleys are quite a bit smaller than our previous set, reducing a little more weight.
