So my turbo miata seems to have a massive oil addiction. Compression has always come back good but I was using like 2 quarts every 700 miles or less. My mechanic lent me his leak-down tester and I got terrible results, however I was wary that I wasn't using it properly so I had him check it as well. He said it was the best engine he's ever tested, less then 5% on all cylinders.

This leads me to my question, where is all my oil going? I have some seals that weep but I don't leak enough to leave puddles on the ground. Intercooler pipes are dry and the turbine outlet is also dry.

Am I missing something dumb? The car is all stock now (yearly inspection) and I plan to put some miles on it and see if the consumption is the same without the turbo.

The car smokes a lot with the turbo on as well. I think I have a rebuild kit laying around so I might put that on just because.

Any help would or ideas would be appreciated.

Thanks,
Patrick

turbo seals probably dead. Are you running an oil restrictor?

did you ever mess with the baffles in the valve cover?

I think I gave my oil restrictor away, I had read that journal bearings shouldn't really need a restrictor and I had intended to rebuild my turbo when I got it. I actually have two of the same center sections and I think I swapped to my non-rebuilt one because of another issue I was having (was unrelated).

I've been rather busy lately but I'll try and tear the turbo apart tomorrow and see what I can see.
