Help Blue Smoke??

I have blue smoke everytime I crank it up. Also when I give it some gas and come a stop it puffs out blue smoke. I dont drive it very much and I have LG Pros with no cats and B&B Bullets and no tune. Will a tune fix this or is there something wrong? I know blue smoke is oil. Will a oil catch can help this problem? Thanks!!

Will it smoke if you drive it awhile, shut it down and then restart 5 minutes later?

How many miles on this car?

What year is it? Could be that a lot of oil is getting into the intake manifold via the PCV system. If a lot of oil accumulates, it could run down the intake valve tracks as it sits for awhile, and then cause blue smoke at startup.

You should pull the PCV hose and look to see if it's heavily coated with oil on the inside. Or pop the hose off the front of the throttle body, then look inside the intake manifold to see if it's coated heavily with oil. If so, then yes an oil catch can (Elite Engineering makes a real nice one) might help this problem. If there is heavy oil residue, then it's likely that the oil separator underneath the valley cover is leaking oil past it and into the PCV hose.

Hey, no problem - glad to help out. The 99 model year LS1s don't have the PCV pickup under the valley cover, so that probably won't be the issue. It can't hurt to checkout the PCV system hoses and intake to see if there is excess oil though.
