i rebuilt my k241 because it was burning oil.
it was running great every thing i did was by the kohler repair manual.
piston clearance is .0075 - ring gap .010 - rod clearance .001 - engine is full of straight 30 weight oil right at the full mark and timing was set with a timing light .
after a total of 4 hours running as near as i can tell the rod seized to the crankshaft.
i was cutting my lawn a 3 hour job it slowed down and quit right after it started blow huge amounts of white smoke out of the crankcase breather.
the rod is a saint bird brand do you guys think it was a bad rod to begin with as i have never worked with that brand rod before.
the rod was installed with match marks together and oil hole toward the camshaft as per manual.
block was cleaned well before assembly to remove grit from honing
the rod is .020 under as the crank needed to be turned down to .020 under .
ideas guys the more the better.
