new race car, no oil pressure

-
OIL pump is not flush with main cap. As was said before you have to us a bolt or machine down the oil pump bolt surface on your main cap, as well as shave stud on top and bottom and us a special low profile nut to get the clearance. you need.

If you did NOT do this, your oil pump is probably broke.

Simple test
temporally install you intermediate shaft and see if it gets stuck or binds.

If it does, you will be pulling your oil pan/pump to fix the problem.

not driving the tube in to far, not driving it in far enough. if he only drove it in far enough to get past that last lifter bore, then he could have the passage coming up from the oil filter blocked off.

also, I wish it were as simple as a defective oil filter, but I already tried another one, and got the same result.

I know the oil flow diagram I posted is small (sorry, all I could come up with) but your not looking at it correctly. He could drive the tube in until it hits the rear wall and it will not affect pressure to the other parts.

Do you know if he clearanced the pump for the ARP studs? Was the oil pump disassembled and clearances checked and cleaned thoroughly before it was installed? That's something that needs to be done EVERY time you install one. You wouldn't believe the garbage I've seen in brand new pumps.
 
GOT THIS PROBLEM SOLVED BOYS AND GIRLS!!!!

it was indeed the rear copper tube that was installed. he had not driven it in far enough, and had the main passage coming up from the oil filter, blocked off. got the engine out of the car, and removed the plug in the rear, that lets you look down the passenger side oil galley. just pass the threads for the plug, was the copper tube. went over to the corner of the shop, and took the same plug out of my factory 340, and just pass the threads, is the main oil feed hole that comes up from the filter, and feeds the main oil galley, the oil pressure port, and the rear cam bearing.

so, Fishy, it does matter if the tube gets driven all the way to the back. it covers the huge oil passage from the filter, and nothing is getting oil!

thanks for the suggestions guys, I'll let you know how it turns out. taking it back to the engine builder saturday, and he is going to do a complete teardown, and endmill the tube from the rear, until he uncovers the oil passage.

So what your seeing looks different than the diagram I posted? It's from the factory service manual and I assumed it'd be correct. When I said he could drive it till it hits the rear wall and it wouldn't affect the other parts of the engine I was going by the factory oil flow diagram. I'm sorry, apparently it is wrong or I just can't follow a diagram. Any time in the future I won't waste time trying to help someone without seeing it up close and first hand. I have rebuilt several small blocks but never had a reason to sit and memorize the oil flow. :eek:ops:
