Default Oil Pump Pick-up

I have to admit, I have been away from rebuilds for quite some time.
What are the current thoughts on attaching the pick-up tube ?
My OLD days, was just a couple of brazing spots, no disassembly of the pump.
What are People doing now ? Lock Tite, or something else ?

Thanks,

Bill

Last one I did, I put a small bead of Loctite around the tube, checked the clearance off the bottom of the pan, then hit a couple of quick spots with a MIG welder.

I MIG them all the way around.....the reason is to prevent aeration....not so much for strength......brazing is an option too.....

Default Another Idea ?

Thanks for the answers.

Working midnights this week, maybe my brain is fried, but I have another question.

Would there be any drawback to flux and solider ?
My thinking is, copper joints are strong, and maybe a little less heat.

What Ya Think ?

Thanks Again,

Bill

I have always MIG welded mine , why take the risk? ... Some say its not necessary, but I dispute that.. I have seen two come off , not mine, ..one just pressed in, one with Lock-Tite.. Easy to tell, when one comes off.. first the tapping noise of crank hitting it while it moves around, and second, oil pressure falls rapidly on braking

Mig welding will not adhere to cast very good, brazing is probobly the best option or I like to weld a tab to the pickup tube and bolt it into place with locktite on the bolt threads.

I've had a pickup tube fall off after being MIG welded on.

Real welding or brazing. I use a Milodon pickup and it has tabs to bolt it to cover bolts. Works great.

FWIW (if only point out that there are other alternatives), I have a submerged, bottom-feed pump setup. No pick-up tube to fail.
