low oil press problems at idle

[DriftingFC]

Im runnin roughly 17-21 lbs of pressure at idle and I can get 60-70 @ 3K rpms. Its a fresh rebuild, so I dunno if that could be a problem. I am honestly thinkin that my front cover O ring mite have squeezed out. I cant rev to 6k cause its a fresh engine so I was hopin for some ideas from you all of a possible other culprit then the O ring. :D

Thanx.

Did you torque the oil pump down to spec and bend the lock washer up on the side of the nut?

[DriftingFC]

Yup. It was my frist rebuild. (engine was actually in pieces when I got it) I spent 2 months reading, re reading and asking questions, checking all tolerances, clearances, the housings, the irons as the manual says to do. Even mocked up a junk engine that I had to make sure I did it right. Took it apart and did it again before I put this one together.

All torque specs were followed. This wasnt my frist engine I have ever rebuilt, just my forst rotary.lol

15psi at idle is normal.
What were you expecting?

I was going to say.....that is not low pressure. I get around 20-25 at idle (when warm) and 70+ depending on RPM (anything over like 2K rpm).

When Fero313's FC had low pressure, it was ZERO at idle, and would bleed a little when sustaining RPM's. Then you have a problem!

Mazda’s specification is 50psi @ 3000 rpm minimum on 3rd gens. I run a 1000-1100 rpm idle to float the bearings better.
