Bad340fish -

What kind of cover did you have on your pump? A flat one or a recessed cover like a Milodon? How long did that pump last ?


My comment was more to say that the oil filter probably got most or all of that material. Mine was a small block Melling High Volume that chowed down some needle bearings from a rocker arm failure. I should have take a picture of the pump taken apart it was ugly but it fit lots of needle bearings through it lol.

Mill or no mill, there is no "easy" fix. To the best of my recollection those pump covers are all hard anodized. Mill it and run it and you'll have the same issues in a very short time. You have multiple issues to fix, the pump cover is just one of them.

65 A-990 race Hemi used aluminum pumps without being anodized. Never saw one go bad as long as the engine was built properly and didn’t experience a failure.
But like I said earlier, anodizing does help durability and allows the pump to digest some particles.

Beyond checking all clearances for the pump, I would pull the pan and check some bearings. That missing metal is a lot, and it went somewhere.

Problem solved! Recommended intermediate shaft and installed shaft were different lengths. Pump primed and fired up with more pressure than it's ever had at idle. I let it get to ~110 before shutting it off as I thought the pressure was excessive (it dropped once it warmed up). Per all the comments above; I contacted Milodon about the torque specs. I was told "Spark plug tight. Snug plus 1/4 turn." Also from the above comments; after following the Milodon directions, I spun the pump by hand with a screw driver and intermediate shaft with no gear. Next I spun it with a drill and monitored oil pressure. Several over precautionary steps in between and it's happy!

Any idea why the diff lengths? Guess I got to assume some aftermarket race blocks use that???

Did you cut the oil filter open?

I hope not, but at this point it is what it is. The damage was done at start up. This was a scheduled oil change and the car was running fine. The first oil filter would have been the one to cut. That was last year and no I did not open it up.

There are three length shafts to accommodate the different pumps.
The shortest shaft goes with a stock style pump.
The middle length is used with the Milodon 21815 pump.
The long shaft is used when you’re running the sandwich plate between the pump and the block.

Thanks Dwayne….

….and if that was my W8 mill I’d tear it down. If it was my iron headed “Bracket Betty” I’d RUN IT!

I'm going to do some more inspecting this weekend. If it's bad, it's going to sit for quite a while (shoulder surgery in a couple weeks).
