Exclamation Problems with ls1 i need help

Ok 109k on engine, so when i get on the throttle it smokes, when i rev it up it smokes and when i sit there and let it idle to starts to smoke the smoke rolls out of the exhaust, The motor is stock only thing is cats have been removed, i thought it was cause it was running rich, but i called and he thinks its more bigger issue, does any one know what this could be?

Default Smokin

You are talking Oil smoke

If so, has the smoking been gradually becoming worse or did it just start happening all of the sudden?

How does it run? Did anything else happen, or was it just the blue smoke?

I would say bad piston ring, or possibly valve seals. Check your spark plugs, look for oil deposits and such so you can narrow down to which cylinder (s) is give you the problem. Once you narrow it down, if you can, do a compression test, and cylinder leak down test. That should tell you if it a ring or not.

Does it smoke alot when you start it up in the morning and then slowly go away, or is it constantly smoking. If it just does it when it is first started then its probably a valve seal. If its constantly smoking, then I would guess a ring. Also check and make sure your pcv valve isnt clogged. That would cause excessive pressure in the crankcase and force oil past the seals into the cylinder, and also cause other oil leaks.
