Loc-tite on cover bolts does the trick.

Pump clearances are checked with feeler gauges.

I have no idea on the thin pump issue, as I have about 4 of the old style left, bought years ago, and haven't used them up yet.

I have seen links posted on other race forums to the Milodon pump, that they currently sell, and it is a heavy casting.

I would use what I have already which is 7qt pan and matching pickup but don't know if that's when used with standard size pump I'm guessing so that's what got me looking to begin with, plus I figured 3/4" pickup might not matter but it shouldn't hurt either. But at same time if I get other pickups there not cheap.Now trying to get and decide on pumps. I figured checking clearance with feelers but how?

Yes sir,but I have no issue with buying one.But if the castings are not thin/weak anymore like sum say then why buy a $100 one if a $50 one works just as good for the most part.Just trying to find ones that arent and since there can be boxes of old thin ones still out there I wont know it until I recieve it or someone opens box for me to confirm it before I buy.I have none to look at before purchase myself.It really is frustrating not being able to go to store and look at.

I just spoke with a Tech george from melling and he said " The standard M55 is the thing model started in 2004 " and if I want the " THICK " casting purchase the M55A

And the spring installed " Pink " i believe is the 78lbs spring and if I wanted the pressures of the standard M55 just swap in the extra spring included in the box.

He called it there " Z28 " oil pump

After reading about all the troubles with melling pumps why wouldn't one just buy a milodon pump? They have all the accessories including oilpans. Lil Joe

You remove the cover bolts, slide the cover to one side, and use it as a "straight edge" to check clearance between the cover and the top of the gears using feeler gauges. Too little clearance, sand the ends of the gears on a flat surface ...too much clearance, sand the pump main body where the cover bolts on

.0025"-.0035" was the often quoted ideal spec, Lingenfelter Racing says, .0025-.0033". Check the gears for burrs first, by running them across a flat surface backed 220 grit paper, then wash and measure.
