Default MAJOR SMOKE at 76k??? HELP!!!

I went to look at an 2000 coupe today. Clean car, pacesetter headers , no cats, o2 simulators?, and some sort of SLP exhaust system. I think it was just SLP tips, got the car on the lift.. I had a buddy of mine drive it while following and noticed a sh*t load of blue/grey smoke at high RPM. From looking at the exhaust set-up: NO RESTRICTION! Have any of you seen anything like this?

The intake tract could be loaded up with oil from the PCV Sys OR The rings could be weak/bad! Your pick!

Just figure out new crate engine + Installation Subtract from Selling price you would pay, This should give you a good ball park value given the "car" is ok.

Another choice if the car is the right price is buying a take out motor like a few that are for sale in the parts section. Since it is smoking at 76k though I would go over the rest of the car with a fine tooth comb to make sure the rest wasnt abused as well.

Do a compression test if you are interested and find out for sure what the problem may be,76k is nothing for an ls1 it may be a bad pcv system ive heard of it before or it could be serious.

There is a documented issue with the #2 piston rings in LS1's but I cannot remember the date range, thought it ran up to 2001, but cannot remember when it started. Only looses oil at higher rmp since it is the #2 ring on the pistons. I am sure some one can link the document about this or at least name the dates of vehicles affected. GM has a fix "kit" to solve the problem, at least they did when it first started occuring.

Default Thanks!

Tomorrow, going back to do a compression test. This brain-dead idiot has diven this car everyday day for 2 years and never changed the plugs. MORON!!! I guess the exhaust was more important. Anyway, Thanks for everyone's 2 cents. I appreciate it.

FWIW: My green C5 did this. Like BAD. I thought the motor had blown or something...

Then you know what happened? It all cleared up and went away. All on its own. Never happened again.
