Quick oil pump question
Quick oil pump question Ok, so the book says to always replace the oil pump during a rebuild. I'm assembling my 383 for the 2nd time. I took my stock pump apart, it's pretty simple, 2 gears and a housing with a melling drive shaft and coupler. I don't have a problem spending $40 or $50 on a new one, but this one shows no significant wear and who knows how good the replacement will be. Anyone have comments on this? Thanks!

I beg to differ. The oil pump is the most well-lubricated part of the engine. And with only 80,000 miles, the pump itself is likely in good shape. I wouldn't hesitate to reuse it (depending on his build specs), as long as he replaces the plastic coupler on the drive shaft.

Thanks for the input guys, One point that concerns me is choosing between a proven part that exhibits no appreciable wear or defect and trusting my engine to a replacement unproven part that could have a manufacturing defect.

Get a Melling 10554, add the white GM spring and be done with it.

i had the gear in the top of the motor shear off on my lock my oil pump up. and luckily i noticed the loss of oil press. (due to my LED wired to my idiot light lol. shut the motor off and almost wiped out my entire motor. all becuase when i did my 383 i didnt replace it all. my suggest. would be to replace it all. its not worth losing a motor over a small part.
