Re: Advice? Oil Pump and Carrier Bearing

On the carrier bearing---take it to a reputable drive shaft shop in your area, rather than taking a chance on munging up the drive shaft.

On the oil pump--- I always set the pick up WAY to low & then use the oil pan to push it into place. Then I push the pick up tube up about another 1/2", or so, and tack the tube to the pump using nickel welding rod.

But that's just me.

Re: Advice? Oil Pump and Carrier Bearing

Oil pump? I've rebuilt my own with suitable mods for over 20 years with many many racing motors involved. Melling has gone to crap in MHO, I prefer to redo them as they should have been done from the factory but the machining costs would drive up the price. A good place to start (its a little old but relevant) is Smokey Yunick's mods. Unless you are dealing with a total meltdown piece. I have nearly 5K in my current motor and guess whats the only used piece in the motor? Yep Oil pump.... I run 3/8-1/2" or so away from the bottom of the pan. Never used El Jay's technique but seems like it would work well. Needs to be welded on but make sure you have removed the pressure spring. I used to block the bypass but don't do that to my street motors anymore. I don't run a high volume pump...never have never will. Chevy only needs 10psi per 1k rpm. Good little oiling system. Use Chevy spring Number P/N 3848911. If you do the mods correctly you will increase reliability and reduce power consumption and spark scatter among other things. YOu will have a pump that I have never seen from the factory.

It doesn't take a whole lot of weld; maybe 3/8"-1/2", just enough to make sure the pick up tube won't vibrate out of the pump housing.
That nickel rod flows like butter.
