I believe that blue smoke from the exhaust indicates the burning of some oil.

turbo burning oil?...but seriously,how's your oil pressure? Also do you leak any oil on the ground?

haha i wish i had turbo.... No oil on the ground and the pressure is halfway to 3 quaters. I did notice on my trip to saratoga over the weekend it seemsed a quart low on oil now today i checked again and its fine....

Well from what it sounds like there is some oil burning probably not to much. As long as your oil pressure is fine and you dont start creating clouds that can hide armys then i would not worry to much about it.

i know but i do hahahha ill take ur advice ski

skifast87

trust me man i know how that goes. My father has always told me "you worry to damn much about that car" Ill here the smallest slightest noise one time and i will chase that thing all over the chassis. I know how that worrying thing goes.

If the blue smoke is at start up, oil could be leaking down through the valve guides while it sits. If blue smoke is coming after it's warmed up, when you romp on it, it could be blowing past the piston rings. But with only 50k on it there shouldn't be either of these issues. Are you sure it wasn't just some carbon burning out?

2 people told me they seen in when i got on it from 1st to 2nd i havent seen it yet.. I put and additive to help the seals hopefully that solves my prob thanks guys.....

if it smokes on start up then probably your valve seals are tore. But you say it smokes sometimes while driving it might still be your valve seals but probably your piston ring or rings starting to go bad.

Have you installed a catch can?

If you're running m1 5w-30 that stuff is known to be thin and can aggravate oil consumption. I'd go with 0w-40 M1 or GC 5w30 if you can find it. Secondly, add a catch can and it should help a lot.

no catch can instaled and yes im running 5w-30 you dont think 0w-40 would be alittle to thin?

Starion

iTrader: (5)

The 0w40 is supposed to be thicker than 5w30

It's probably just burning oil that's making it's way in through the PCV system. LS1s are notorious for pulling oil into the intake through the PCV. If you pull your throttle body off the intake it'll be obvious if that's what's happening. If it really bothers you put a catch can on the PCV, or do the conversion to the LS6 PCV system.

If you stomp the gas from a cruising roll, and you get a cloud of white-ish-blue smoke, and than it clears up as you CONTINUE to stay on the gas and accelerate......its your valve seals. Also, check for wet oil on your plugs, another tell tale of bad valve seals.

When you stomp the gas it creates a huge drop in pressure, with bad valve seals on either a single or both heads, the oil from under the valve covers gets sucked in through the bad seals at that moment, but than it doesn't keep getting sucked through as you continue to accelerate.

I had this exact symptom, I had my heads rebuilt and it 100% cured it.

If it was bad rings, the trail of smoke would continue as long as your on the pedal.
