oil pickup mods. What do you recommend I use? Thank you for your time.

I'm wondering why you are using epoxy at all. Please explain.

Do not leave epoxy exposed to oil, it will eventually swell and dislodge/debond. Why would you want to use an epoxy with a vibrating oil pump.

be careful, it's quite difficult to gas weld cast iron. You might be better to braze the tube into the body. Less heat and less risk.

I Meant braze..to many old timers around here called it torch welding and would say gas welding is the only real and true way to weld anything. old habits

Pickup tubes are easy to mig or tig weld. I wouldn't think of a jb weld patch on on something that critical.

Vibrating oil pump? It would seem If you have harmonics that severe his pick up would be the least of his worries.

An oil pump is a bit like a tuning fork. The pickup is flexible and has mass on the end. Take a hammer and bang on an oil pump, you'll see the pickup wiggle, especially at its resonant frequency. The engine firing pattern does the hammering.

I have broke off the entire oil pump from a BB chevy more than once from tire shake. They make a brace to keep it from happening, I fixed it for good by going with a belt driven external pump.

When you start making power you learn about these things.

I agree with the tire shake issue, That is an effect from outside the engine.
Im just not sure about the comparison of Banging on the case of a oil pump with a Hammer and resonant Harmonics from an oil pump operating as intended.

So am I.

To the disbelievers, there is A REASON why Chrysler supported the end of the pickup tube by placing it on the floor of the oil pan.

But if you don't want to learn or understand, there's no help for you.

Sorry I'm just a lowly Electrical Engineer.
Your intellect is obviously far superior to my own.
I bow down before you!
I'm pretty sure most all of the manufacturers support or have a distance they keep the pickup of the bottom of the pan so it stays submerged in the oil.
Im pretty sure it is not recommended to set the pickup directly on the floor of the oil pan.

It is indeed a much better design (as is usual for Chrysler) than the GM configuration where most of the experience with brazing the pickup was developed.

I think this discussion started with the question of gluing the pickup in for reinforcement, a bad idea no matter what the design given the heat and oil exposure.

Don't you dare apologize, everyone knows mechanical engineers are the ones who couldn't cut it in the EE dept.
