this has been getting at me for a while but in my shed i have an engine i removed from my old rst as it had low oil pressure at tickover and was knocking.
when i dismantled the engine the crank and shells were unmarked yet with the crank bolted in place you can still move it up and down
is this due to the wrong size bearings being used when the crank was fitted?
everything else on the engine was brand new
the engine had only done a couple hundred miles and i still have the reciept for it,was from a company named rogersports
