Found my oil PSI issue or so I think
Well as some read my motor had 0 psi at idle but shot up at higher RPM's. The oil pump turned really free with a drill, almost to free.
Dropped the pan last night and found the pick-up tube came out of the pump. So I went and picked up a new high volume pump with a steel shaft and retainer over my old pump and plastic retainer. Put the new pump in an got the new pick-up tube jammed in there really good and put everything back together. Hooked the drill up and spun the pump to prime it and bam she caught really hard and slowed the drill right now. Big difference and the gauge even picked up pressure.

I put a spot weld on the pickup tube to keep it from falling out. Old trick, but a good idea.Jack

I've never done the weld trick, but it IS a good idea..
Education is expensive. Keep that in mind, and you'll never be terribly upset when a project goes awry.

Some of the aftermarket pickups, Milodon, Canton, and others have a bracket that secures the pickup tube to the pump. The weld trick on the pickup works great, too!!!Yesterday is history, tomorrow is a mystery, Live for Today!

welding them works good but here are some tips. if you spot weld with a mig then tape off the pick up and the pump body outlet to keep out the spatter i wire wheel the body off were it was welded so it clean of any bits of steel that may fall in the pump pick up then i blow it off before i take any of the tape off . brazing works but it gets the pump very hot and you need to take the oil pump apart so you do not kill the spring and you need to get all the flux glass of the brass joint. what i use and works the best is tig welding and i tape the pick up and body to but there is not much of any spatter S steel filler rod works good to tack the pick up on and when done and cool i wash the pump and blow out and run clean oil thru or fill the oil pump with lithium grease-lubeaplate with the botom cover off the oil pump oh when driving the pick up in the pump body do not do it on the engine lay it on a phone book and drive it in this way you will not hurt the body of the pump body that can start a crack in the pump body and the pump and pick up will be in the bottom of the oil panLast edited by pat mccarthy; 12-25-2006 at 08:19 PM.

them pick up work good that bolt to the main body BUT i have seen them crack at the bolt hole so i do not use the lock washer with them. but loctite and a much thicker and wider washer then they come with to help hold it on and i use a dab of loctite on all the pump bolts and file the pickup tube end round it a bit so it start better and help from driving junk from diging in and making steel when going in the pump body

I had a '63 Pontiac 389 where the pickup fell off, and coincidently at the same time some of the teeth on the plastic timing gear started to come off. One of the teeth got sucked up in the oil pump and jammed it up, breaking the oil pump drive shaft. The car quit running, and I worked on it for a week before I found out what had happened. Couldn't figure out why the distributor wasn't turning the pump.
I changed out the timing gear for a steel set, and obviously never had a problem again. I think Pontiac was using the plastic timing gears for a while to run quieter, or something, but in heavy duty use they were failing.

[QUOTE=pat mccarthy]dave you are working on me well that could be it dave but not all .oil hitting things and roping in the pan at 7500 rpms after time and i am sure some harmonic. but the ones that i have seen were the ones were the hole is very big on the tab .and the tab just is not very wide so and not flat to the body of the pump there is not much there and if you think about this. on some pans the pick up hangs way down ? so in time some things will move . and i do know of a ford 302 engine that the pump did break off at the bass so i know them chevy are junk but this happens to them fords to.[/QUOTE
Yeah but Pat, if I didn't take every opportunity I could to mess with you about the chebbies, you'd be way ahead of me on messing with me and my Fords!!!!!
As for things breaking inside of Ford engines, if it's in there, I've broke at least one of them!!!!!!! Guaranteed!!!!Yesterday is history, tomorrow is a mystery, Live for Today!
