how hard is it to install an oil pump?are there any tricks or things to watch out for or should do when installing it?also would a high volume pump be better than a standard volume one?

Try to get hold of Patter. The last time I heard he had his oil pump installed but was having a problem with the belt drive for it. Surely by now, with Ed helping him it must be installed...........he is located in Dothan, Alabama.

The oil pump is easy to install, getting the oil pan off is the hard part.

You will have to jack the engine up off the frame about 4" (put 2x4's betwwen the engine mounts and the frame mounts) to give you the clearance to remove the pan.

oil pumps don't usually go bad on Chevys, are you sure you need a pump or is your low oil pressure ffrom worn out bearings?

Make sure you have enough clearance between the pan and the pump. Since you can't see this clearance use the clay method and a vernier caliper to measure the clearance.
For a few cents use a new collar on the shaft too.
Weld the pickup to the pump so it doesn't come off.

I'm assembling my long block this weekend and i'm wondering about this too.

What is a good clearance to run between the pan and pickup. I was thinking like 1/2 an inch, but i really have no idea.
Anyone?

my oil press is really high it increses as the days go by first it was about 20 idle then it was 40 idle now its about 55-60 idle.so i figure its my pump or my bypass valve is stuck.
bob tiley is talking about jacking the engine up off the frame about 4".....i have car ramps that take the car up off the ground about 6-8 inches.....this wouldnt be enough or is there something i dont know about that im miss interpreting..

p.s GTO68TX...im not really from alabama and ive heard this answer many of times i dont feel this question is dumb compared to some of the things people post.i think you need to get a hold of patter and go hang with him because your closer to alabama than i am and judging by your "totally ORIGINAL quote" your a pretty smart guy...you need to put that to use...maybe you can help him build his "rasecar motor"

Matt - I set mine for 1/4". I spun the engine upside down, bolted the pump in place, shoved the pickup into the pump with it sticking up enough so that I knew that it would contact the pan, and dropped the pan with gasket onto the block. By dropping the pan onto the pickup, it moves the pickup to "0" clearance. I then moved pulled the pan off, moved the pickup 1/4" closer to the block and welded it in place.

Dumbguy.......any reference to Patter is done with humor. Most people in this web site knows that. If you are not from Alabama then why list it as so?

Outa the car it is gravy
One thing you guys forgot to mention is how much fun geting the pan back on is
Trying to line up the pan with one paw while trying to start the bolts while taking care not to mess up the gasket is a real joy. Use of a drift punch or somthing similar to line things up is helpfull. I was planning on getting studs for my oil pan because I think it might be easier to do the whole deal but who knows. ARP and others make em and they sell outa Jegs. I havent used em but plan on it cuz I think it will make life a little easier if I ever drop the pan in the car. Good luck and like the other guys say I would look for the easy solution before I take on swaping pumps.

Mike, Thats a pretty good way of seting your pickup, going to have to try that next time. Thanks for the tip.
