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 ***.
 
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.
 
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.....?

that's what i thought too. looks like somebody clamped that bad boy up to wrench on the pick up would be my guess.
 
Yeah someone gave that a nasty squeeze lol. All for the sake of what $40-50??

I don't doubt that is true, but the responsibility lies with the company management and executives that allow this kind of crap to get out to customers. It's not hard to setup a robust Quality Control system in a manufacturing plant and they have tons of experience with it in the automotive part industry. Of course you need some level of buy in from the employees, but again that is up to management. Kinda falls under the "management" title. What else are they doing? It doesn't matter if the plant is in Michigan, Mexico, or Asia. If this was truly a new out of box part and not some sort of return or fake, someone at Melling should lose their job.
 
My gal friend has a daughter in Minnesota, she was in quality control a a business. None car related. When she failed parts, she would get called into the office. She got tired of that and found a place that did care.

Was the pump on an assembled motor, so no telling what it actually looked like new out of the box?

Exactly think I heard about them here and man after checking them out I was like worth every penny. I forgot they have the hardened prime shaft too for the high volumes.

It I agree. Looks like someone put it in a vise to get the pickup on/off. Like mentioned above, I blend/port and clean. Check clearances. And
"If" The pumps good I would use one of these.

Just run a file over it and clean it up. Geez. It's not like it's Melling's fault.
