No oil through OMP lines after rebuild
No oil through OMP lines after rebuild
Hi everyone,
I noticed no oil going through my OMP lines after my rebuild first start. I kinda freaked out and shut the car off after maybe 30 seconds. I did premix and lube the housing before the start up in fear that the OMP wasn't going to work.
How long after a start up should I see oil flowing through the lines?

It takes a while for the lines to fill with oil and like Dale said, Mazda recommends filling them before installation. This is a pain in the *** so I always add premix to new builds. In fact, I feel every rotary benefits form premix.

It would be a ROYAL job to do this once the motor is in the car. I would probably just let the car idle and run with no load until the lines have oil in them. You should have plenty of assembly lube in there.
I've done many engines over the years with dry OMP lines. I typically run the engine for 15-30 minutes at idle and maybe revving a bit in the driveway until it's warm, then change oil and filter and let it cool to make sure the coolant is topped off. Then start driving. I've NEVER had a problem with it. The motor that's in my car now that I built 10 years ago I started just like this with dry OMP lines and no premix and it's still healthy as a horse.
In general, I think it's a good idea to pre-fill the lines. But, I don't think you're hurting anything not doing it.

I did...something...to fill the lines when I rebuilt my engine...but damn if I remember it now! I put the stainless lines on and was worried about not being able to see any flow. I seem to recall using a little syringe I had...probably all just ended up draining into the engine, but it made me feel good, lol!
