how can the filtre screen on the oil pump cause a connecting rod to break off a piston?

Question

gm pick 1980 v8 small block engine. only has 1000kms. new crate engine

Answer 1

If the filter screen is clogged, it will restrict or even completely cut off oil flow to the engine. This can cause spun bearings, which in worst case scenarios, will cause the connecting rod to seize on the crankshaft and break free of the piston. More likely than not, however, if your oil screen is your culprit, it probably came loose from your pickup tube and lodged somewhere in the cylinder wall or the crankshaft, causing the failure.

Answer 2

quite frequently definite. at the same time as i replaced right into a nipper my moped had an oil pump. The wormchronic that operated the pump were given mashed. So the pump wasnt operating. subsequently the piston scored the hell out of the engine and this is going to certainly siezed. i comprehend in my case it replaced right into a 2 stroke notwithstanding a similar princliple applies. No oil circulating around the engine = a knackered piston. U might want to be fortunate if the engine replaced into in operation for possibly a minute after the pump failed. If its "nevertheless operating yet slowly includes a hault." Sounds to me like a partial engine seizure. identity say its a significant engine overhaul or a sparkling engine. notwithstanding im in basic terms an newbie mechanic. I dont take care of it day in day holiday. So it will be a diverse tale. yet thats my wager from what information youve given.

Blocked oil pump= no oil pressure= damaged engine

Answer 4

Sounds like a bad assembly job/ lousy parts to me. Whatever it it, the pump is part of the motor.
