Hey Guys -
I am having trouble with my 2000 SS LS1 with smoking (I believe burning oil) on deceleration. It's a mostly stock vehicle with 74k miles on it.
I noticed no issue on it when completely stock (up until 72k miles or so) nor when I swapped an LS6 intake onto it. Late last summer, I ended up upgrading to the Hooker TD system, and this is when I noticed the issue. I assume the stock cats were mitigating the problem.
I notice anytime I get on it relatively heavily, a few seconds after letting off I get a puff of smoke, and it smells like oil really strongly. I've added a homebrew catch can (with media in it, I really tried to mimic the good aftermarket cans) and notice no difference with it connected or not.
It also does this when on the dyno - so it's not like oil is sloshing around somewhere. I did have some light oil buildup in the stock LS1 intake, but nothing alarming at all after 72kish miles of driving - it really looked decent to me. I also don't notice it consuming oil drastically or anything. When I hooked up the catch can, I also put in a glass fuel filter. I see a little oil vapor coming through, but I don't see anything that would cause something like this. I am not ruling out the possibility of it being PCV driven, but I don't think it is.
The video below is a good representation of what's happening. The car was on the dyno, and right before the 40 second mark when the operator lets off, watch the driver's side exhaust tip. A few seconds later, watch the passenger.
Any thoughts or experience with something like this?
