I have the engine in-frame and stripped down. Here's what I'm stuck at:

1. The manual states that only exhaust valves have a rotator and O ring seal and intake valves have an umbrella type seal. What was currently on it (and what I purchased as a replacement) are these: https://www.external_link/ABC4758-Valve-Stem-Seal.

Which one is correct? Do all the valves have the cylinder type seals? Is there a photo diagram somewhere out there that shows exactly how they should be?


2. The good ol' piston ring gap issue. The engine itself is within specs but the turkish set of rings I got are about .060 ring end gap. The rings I took off were about 1/4" and the thing ran good! Looking at just getting .030 oversize rings and filing down if needed. Thoughts? Please no fighting! :).


3. The engine block has two small chips where the water outlets are on the top on the left engine side. The chip is big enough that the water can bypass the head gasket and get to the oil supply. When starting it blew tons of white smoke but after startup ran pretty good. Terrible to start though. I'm thinking that these chips and the blow-by explain the hard start-up. I'm using the steel reinforced JB weld after sanding down the block chips real good to support it. It's low compression there so should be just fine?

Other than that. Good old tractor and I pray it runs after this!!!
