I have been going through about 1 qt. of oil in about two days when i boost it. But if i just drive around in vac. it dont burn off? So that mean that the oil seals are shot or do I only need a restrictor to stop this problem?

Oh and I killed my manifold today at the track. Ebay crack master

 

rebuild? help?

 

you would notice if you were burning oil in boost....those big clouds of smoke are fairly obvious.


what size oil inlet?

 

I had a similar problem. I am running a T25 from an SR20, with a -4AN inlet. I was having an issue where it was making the CHRA leak, and I was going through at least 2 quarts between oil changes. So I used an 1/8" pop rivet in the inlet fitting, and every now and then I still smell some oil burning, but it's been 700 miles since my last oil change, and no oil consumption. I'm not saying a restrictor 100% cured my problem, but it sure made it a lot better.

 

hell, i had to go from a .065" restrictor to a .040" with my -4an line.

 

I am running no restrictor on my my T25 and no smoking problems <knock on wood>.

LOOINEY. Are you using a 323gtx pcv?

 

I have a -4an ss line no restricion on it. And im running a 323gtx PCV. Where do i find a .065 or .040 restrictor?

 

Anyway...that thought slipped my mind. If you are burning oil under boost only, than you are probably boosting your crankcase through the PCV. Convert to a 323gtx PCV from your mazda dealer, not autozone. See if that makes a difference. You could test yours too. Take it off, use the blow gun from your air compressor, and shoot air into the side of your PCV that gets a hose mounted to it; only use like 10 psi. if it doesn't seal off the pressure, it's junk.

 

I just checked that the day before when i installed my injectors and the only problem i saw with it was it dont seal to the valve cover very good. But nothing big i thought.
