Default Turbo burning oil?

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

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

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.

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.
