Hella smoke
 
My evo randomly started smoking like crazy and smells like oil. This is the second time in one week, last time I replaced the turbo and it went away. It's only been a day and now it happened again. Any ideas?

Do a leak down test?

I did and it was fine so was compression. I bought the car from a guy who had recently replaced the turbo because the stock one blew. I probably put 600 miles on it and the turbo blew again. I replace Replaced it with an evo 9 turbo. Put about 30 miles on it and I believe I blew this one to. Any idea why I'm going through turbos?

When does it burn oil? If only at idle, could be your valve stem seals, which was a problem I had before and thought it was the turbo.

So the first time it happened I was driving down a road at 50mph and it started smoking, I believe it only smoked while driving tho. Then I replaced the turbo and it ran great again. A day later I was driving down the interstate at 65mph and it started smoking again. Seems like another turbo issue. Leak down and compression tests were good. I just don't know what would keep causing this issue.

If you are running excessive crankcase pressure, in other words too much blow by and not enough venting, the drain from the turbo is pressurized and forces oil through the turbo seals.

It won't be the turbo.

If you put enough thought into that statement you'll figure out it's untrue.

What's going bad in the turbo? Does the shaft still spin? Make sure the turbo drain tube is clear and not puddling oil in the turbo which will make it leak past the seals and burn in the exhaust.
