Wow...Anyone ever tried replacing the crank banjo with the engine in? It won't come out without the water pump removed, and the water pump is nearly impossible to remove with the engine in the chassis. Luckily I found the bad banjo to be on the mag side cylinder so I won't bother changing the crank banjo. Whew, dodged a bullet there!
I bet I siphoned half a quart of klotz out of the motor. lol
