340 oil pressure? Help

Yeah I just checked and the plug is in I'll try changing the oil when I get the chance and go from there. It wouldn't surprise me if the shop built it a little sloppy unfortunately I heard the bad reviews on him after the fact and the good ones before lol thanks for the advice I'll keep you posted on the outcome

If you want to look/diagnose it yourself, I will give you the advice that my mentor Ken Neve told me back when I was having my oil problem and everyone insisted we were ok:

Get an oil pump priming shaft and spin the oil pump while you tear into the engine (intake, timing cover), look for where the oil is GUSHING out ---> that will be your leak/pressure loss....

Back then the priming shaft was not available, but I had welding class in high school, so I bought the proper size hex wrench (if I remember correctly it was 5/16" hex) and cut off the bend, then welded it to a 3/8" rod... I then took it to the garage that we rented and tried it and saw no oil gushing... Then my nosy brother came in and saw the drill and shaft on the engine and just had to give it a whirl... Suddenly a jet of oil came shooting out from behind the camshaft thrust plate and squirted 6 - 10 feet right at me while I was standing in front of the engine... I lit up and told him to do it again (he thought I was going to start a fight with him at first)... He did it again and another jet of oil came out... We removed the camshaft thrust plate and there were no galley plugs in the holes...

After putting the oil galley plugs in and reassembling the engine, it had 65 psi....

I've had some people criticize me :realcrazy: and say that the camshaft thrust plate will seal the galley holes, but I found differently and ALWAYS use the galley plugs... My experience proved to me that I needed them... It didn't squirt when I did it, but when my brother did, which tells me that it may not always seal properly without the galley plugs behind the thrust plate...

Since then I always run high volume with high pressure spring to get 75.... A little too much oil and pressure is better than not enough... It's better safe than sorry, especially with oil pumps...
