Hey, it seems that my engine is leaking oil at the MOP and seems to be burning an excess of oil! so i was wondering if any of you could give me the exact way to test the MOP!!! I did a search did nor find anythign! i think that this is the cause of my smoke too much oil!!!
Well i need to know what to disconnect and at what revvs and how much oil!
i ordered a Haynes but it has been three weeks still not in i cannot drive my car until i safety it and i cannot do that until i fix the smoke!
Thanx!

 

Leaking oil? remove OMP and replace O-ring.

Testing the OMP? fc3s.org, under How To/Manuals, 89-91 manual. Section D.

Have fun

Where exaclty do i replace the o-ring?
for the fact that that the omp is on the outside isn't it?

remove the three bolts with a 10 mm socket. Pull off the OMP and look at the face that goes up against the motor. You will see the O-ring in a sort of diamond shape. Pick it out with a knife or needle and clean the area and put in a new one. You could probably get away with a generic automotive O-ring from a local parts store. Just take in the old one and match it up.

 

The O-ring is a bit of a funky shape, you'll probably need to buy it from Mazda.

The manual would have told you how do to this.

I'm guessing that the new O-ring will be round and just molds to the funky shape after years of being stuck in that position. Or maybe not!

 

The new one I got from mazda was oval or a trioval, I forget.

I stand corrected!

 

well currious that doesn't help me much i can anybody scan the haynes manual section to test the MOP? and email it to me!? because i am waiting for CANADIAN TIre to get mine in but it has been two weeks now and i kind of want to see if it is working or not! if you could do this would be great!

Whats a MOP and how do I use one? (J/K!)

 

Come on over, I've got one you can use, help me clean the garage!

 

I'd have to say pour out some water and see how much it picks back up?

 

Didn't I tell you how to do this?

Remove the front two lines. Connect scrap hoses in their place. Rum the engine at 2000 rpm for 5 minutes and measure the output. Should be between 5.5 and 6.5 cc's (mL's).

I replaced the O-ring when I did the swap. I have another one laying around if you want it. It is in the shape of a running track.

Could also be the copper crush washers and 5-point crush piece. Those were not replaced.

IIRC, replacing the lines would be a great idea on your car ($150 cdn), replacing the copper crush washers at the same time. For now, just tighten the banjo bolts a little, and perhaps also the 3 mounting bolts, though I set those with a torque wrench.

 

F*ck it all and go premix, actually.

 

ok then my next question is how would i go premix?
what are the equivilants?
