Sounds a little strange but I go through all my bb oil pumps, I open the corner passage going to the oil filter, there never drilled 100 percent. I open and blend openings under the filter. I’ve used Melling pumps for many years but I have never understood why there machining is so half ***.

I disassemble and clean all new oil pumps before I install them.

SB Mopar - Precision Oil Pumps

you pay a little more but these guys go through and smooth and debur and check tolerances on all their pumps they sell, fully blue printed, I have one of these on my current TT motor.

Made in Michigan USA. Probably by an employee without a social security number that cannot be fired or reprimanded. The parts we receive here from many companies are not very well made anymore. We do get some very good quality parts in the wrong box with a different PN#.

This is now the world we live in . And just think what you get when you buy a crate engine that is built using these parts.

Thank your government for this. Tooling is no better. When was the last time you bought a drill bit that lasts more then one pr two holes from you local store.

How about a Pro balanced stroker kit 128 grams out. And if you don't check them they self destruct in a very short time.

Add more pictures showing the rest of the pump. I am wondering if this is an Amazon or eBay copy or a real Melling pump. Either way, give some details too. Are you saying the engine this came on failed during break in? What kind of failure?

There is a gasket that goes between the pump and the block.

Use it.

If you can’t find a paper gasket, Schumann oil pumps has dead soft copper gaskets.

Either way, use a gasket.

 

[Oldmanmopar]

I never ran a pump on a small block without a gasket. You can buy the paper thin material at NAPA. Set it on the main or pump and used a small ball peen hammer and lightly tap around all the edges . You'll end up with a perfect gasket. Use the old pump if you are buying a new one.

IDK but it looks like teeth marks from a vise. How about a picture from the back side of the pump, are there marks there as well.....?

Is there anybody else out there that makes oil pumps besides Melling?
