I'm thinking of clocking (i.e., rotating the body of the OMP motor so that it clears the turbo drain line when I install an adapter plate for a separate oil metering tank) and reusing the original OMP.

I do have a spare one but not sure if it's good.

The original has 100K. How long do these things last?

 

usually around that much mileage

 

Mine started leaking at 55k. I would guess it would have lasted much longer, but since it was covered under warranty.....
