Today...for the second time...I noticed our LS had a puff of smoke from both sides of the exhaust on start-up. It was after we drove it a short distance then turned it off for about an hour and started it back-up. I do not think that the engine was at operating temperature...so...that could be something to do with it.
I cannot remember the conditions the other time this happened...it may have been the same scenario.
Any thoughts? For years, I've been a GM guy and as everyone knows, it's only a matter of time before the valve seals on a 305 or a 350 wear out and they start doing this. I really hope this isn't the case with the 3.9L...especially since our LS only has 57k on it.
I'm not at all panicked...just wondering the cause. Oh...one other thing...the first time it did it was before I replaced the valve cover seals.
TIA,
