Thread: 350 oil problem

Tweet

Help! Just rebuilt a 350, block was bored .030 over, new new everything including pump. When I used the primer there was no oil flow through the push rods. Replaced new pump with a new one. Same problem. Pulled the intake and took out the rear most lifter on left side (#7). Ran the primer and had just a little oil flow.

Replaced the lifter and was running the primer when I notice a large flow of oil just beneath the block casting hole (rear L/H side), hole is too small to see where the oil was coming from so I took the engine apart and inspected the area for obvious defects and found nothing. The cam bearing is the right size and installed right.

What am I missing?

Thanks in advance

Sounds like it may have oil restrictors screwed in the oil galleys. The pipe plugs beside the rear cam plug is where they go in.

We use 'em on solid cam motors to keep so much oil from the top of the engine. Don't work so hot on hydraulic cammed motors.

Thanks Sparky I'll take a look

Thumbone if you find out what the problem is please let me know. I have a 66 327 and I am not getting pressure either I have checked everything I can think of and cant find the problem. I get 17 pounds pressure at 2300 thats not good If you fix yours please let me know what the problem was. Thanks Gary Brown.

Gary, I finally tore the engine apart and found that I had carelessly not driven the rear cam bearing in far enough. It is fixed now.
