hey all...new to the forum cuz i was searching oil pressure woes...

I had a 350 rebuilt and received it as a short block. New high volume pump etc.

It has a remote filter and i'm priming it with a modified distributor.

After 2 X 20 minute attempts, spinning the pump extension shaft clockwise, I'm not getting any oil to the OPSU or top end at all, it is getting a tonne of pressure at the filter (i pulled filter and gave the drill a spin).

I dropped a welding rod into the opsu passage to see if that plug was in there. I read that if you measure 8.5" or less, plug is in. I got 8.5 exactly.

I'm scratching my head here...any ideas?

What are you using for a priming tool if its just a shaft that maybe the problem, You need a dist. with the gear ground off if not you are dumping oil where the dist. goes.

If you leave the plug out uner the main cap it will not cause a oil pressure problem the oil just bypasses the oil filter.

I got a junk dist, took the 'gear' off the end, put it in a lathe and took the helical teeth off so that it won't turn the cam. Its modified distributor...and its not getting wet in the least either.

I can feel the resistance of the pump when i spin it with the drill, oil shot out the filter line when i yanked the filter.

is there any kind of check valve in the remote oil filter adapter? maybe the hoses are backwards

How long were you spinning it, and how big is your drill you are spinning it? Are you using a good mechanical gauge?

Here's a set of Trans-Dapt instructions, they're pretty much all the same.

Remote Filter

It needs to spin the pump pretty quick. If it's a HYD cammed engine, spin I over once after you run the primer for a while. This will get the lifters to change position on the lobe and allow them topinkp up. Oil restrictors also could cause long prime times initially.

well the instructions say if theres no oil pressure the hoses are backwards

[jb88ci]

Yep.... Hoses were backwards ... Switched them at the filter an in seconds I had pressure at the opsu and a minute up to the rockers. Thanks for the help..

sometimes it pays to read the instructions
