oil pressure problem


Hoping to get some ideas. 392 hemi fresh build.


The oil pressure and volume at the filter is good from what I can tell. It will flow hard and fast like a full pressure garden hose when I pull one side off (the return to engine side)

I have very little volume and no pressure at the hole near the distributor that runs to the pressure gauge.

After doing some reading I found that the threaded hole at the distributor intermediate shaft front of engine was missing a plug This is very close to the cam gear. Funny because I couldn't find where the last plug in the plug kit went from HH and figured it was a spare. Installed that. It was fun. Didn't remove anything but the distributor and intermediate shaft for the oil pump and managed to tighten that thing down.

Checked pressure again and it seems like I have less flow at the hole in the rear of the engine and still no pressure.

Before I assembled this I made sure the ball check valve thing was removed. I had a straight shot down to the oil pump mounting surface from what I can remember.
I also installed that plunger that directs oil to the filter that installs at the rear main.

I am using a HH high volume oil pump. I checked the cam bearings before assembly to be sure the shop did them correctly. Im using a spin on filter and relocation kit. But like I said I have really good flow and pressure from the filter side back to the engine.

I pulled a valve cover and see no oil coming up but watched someones video and others commented saying its normal to see almost no oil in the valve train. I don't like it, my valve train seems noisy.

So is there anything else I can check? I was hoping that plug below the distributor would have fixed the problem but the problem is still there.

Anyone have an oil flow diagram for a 392 they can share?


Forgot to mention I put some air into the hole 40 to 60 psi and hear it free flow to the bottom of the engine. No gurgle sounds just air moving inside sounds. Should I get a different result?

Hmm off topic but there is a delete button to make responses easier to find. These are the only forums I have seen like this.

Back on topic. Yeah the upper end is new roller rocker stanke stuff. I used compressed air to verify the openings were lined up and clear etc to the cam bearings before assembly. The hold down holes are lined up correctly for oil.

Anyway upper end is not a concern just yet. Getting oil pressure is.

I pulled the pan and removed the main bearing and the plunger that diverts oil to filter before its used in the engine. is it possible to fish wire through oil passages or is it difficult or impossible?


A bit off topic If I were to not use the plunger I would read full pressure at the gauge in theory because its a straight shot to the gauge port from the pump. Im guessing the factory check valve was there cure to that originally.

I see you've gotten the diagrams at the Forward look site. If plug was missing the oil would go direct to the sending unit, w/o any going through the fllter. The only way oil couldn't get to the sending unit, where you verified the pump is working, would be if someone plugged the passage above where the oil goes back into the block, I'd think.

little oil pressure with it out, but a common trick is to drill a .050 hole in it to lube the cam/dizzy gears.

Yes, it's a straight shot from the sending unit hole out the bottom if main cap is off. The HH Block goes in where the anti drain back check ball you removed was. where did you pit the 'plunger" you mentioned. The oil should have a straight shot at the sending unit when it goes back in the block from the filter.

The rocker shafts should have been disassembled and cleaned during the rebuild, if not sludge & dried up oil could be clogging things up. oil to shafts come up one stand, if assembled out of order, or acam bearing that supplys the oil was installed wrong you'd get no oil to that bank. Hopefully it was well lubed before start up.
