I have a WD45 that heated due to water pump failure (there was a low pitch whistle sound before the tractor was shut down). I replaced the water pump and also the head gasket. Tractor was running fine but now I see antifreeze on the dip stick. I checked the compression and all four cylinders (cylinder 1- 150psi, cylinder 2- 149psi, cylinder 3-148psi, cylinder 4-147psi.). My next thought is one of the cylinder sleeve o-rings failed. If I pull the oil pan, will there be a tell tale sign which o-ring might have failed? Aside from a cracked block, can I replace all o-rings or will I need to re-sleeve and replace the o-rings together on the engine?

you can pull the pan and fill the radiator, then look to see if the antifreeze comes around the liners or down the oil drain holes..... You could do one cylinder... but would be a better long term solution to do it all once.

maybe i miss read the post.. You asked if you need to do LINERS when you do the o-rings.. NO... you can replace o-rings with the original liners ... just clean the block so they slide in easy... probably will be full of old mud and sludge.

Like them all, but love the "B"s.

Thanks. I didn't know if just the o-rings were available on their own.
