Is Turbo bad?

Well under bost it smokes gray maybe a little blue in it.. I checked for turbo play on the intake side and none.
Only smokes when WOT. Does not smoke when it idles. My compression is 153-163 across. My plugs are really lean looking so its not rich. Has to be the turbo right. I just want to make sure before I plunk down the cash.

My intake manifold has a small crack and two bolts are broken. If this helps.

Have you removed the crank breather line from the turbo inlet? This and the PVC valve can cause what you are seeing and which is normal.

The older the engine the more blowby will have = more oil vapors injected into the engine via these two mechanisms. This is why many people bypass these two from the intake and use a catch can instead.

I changed the pcv, wasnt really bad but a newer one restricted flow a little more. I have not remove. Why should I? I did install a fuel filter into that line though. The more I look the more it looks like blue smoke. It doesn't smoke that bad, just a puff and thats it.
