Mig weld press fit oil pump pick up?

Post  Andre.servin on June 26th 2015, 6:50 am

Building my first 460 ford.

Pretty much a stock rebuild.

It's out of a 77 Ford F-250

When I received the engine back from the machine shop the machinist ordered me a new oil pump. Mellings.

It appears to be just a stock replacement with a press fit oil pick up tube/screen.

Now when I removed the old pick up tube it had a ford engraving in it (maybe stock)? The tube was just pressed in with tack welds or anything.

Upon installing my new pump and pick up I can't decide whether to just red loctite it. Or to red loctite it and give it (3) 1/2" little mig weld beads.

For a pretty much stock build, not sure if I have to o as far as welding the tube, not to mention its cast to stainless and all I have is a regular ol' mig 110v and regular mig wire.

If anyone can shed light on it that would be great

-I did do a search on this, I'm sure there is something on it here. But upon my search I couldn't seem to find anything.

if you are reusing the old tube then you will have to JB weld it or tack weld it but don't get it to hot, heat is not good so be careful

Many factory big block engines gave adequate service for millions of miles with a press-fit oil pump tube and screen.
You are building just one ... your final choice.

I've never welded one of those and if I re-use the pickup tube I just use a drop of Loc-tite on the tube before knocking it into the pump. I guess you could weld it if it makes you feel better but it's not necessary.

Yea I'm not gonna weld it. The one that was in there originally wasn't welded in and it looked factory, so no welding it is. If this was a performance build I would maybe then just use a bolt on tube type. But or a stockish 460 in a weekend cruiser? Nah....

Ive seen 2 too many fall out after they were USED ONCE in another pump,

weld and sleep, or wait and wonder?

only takes a sec to tac

I never use to weld them ,and never gave it a thought if both pump,and pickup were new.

Put a small weld on it, be sure to cover all areas so no slag or spatter get into any holes....
