Hello All,I did a forum search with no luck so heres my ?
02 linc ls 3.9 v8 155k miles
This car has progressed from once in a while at startup belching a clould of blue smoke to doing it 80% of the time(at cold startup). It will also at random times let out a cloud at highway speed accompanied by noise from the engine which sounds like it my be spark knock.
My fist thoughts were the valve seals were starting to go bad but when it decides to belch its like a battleship laying down a smoke screen as if the oil was pooled up someplace and dumped into the intake airstream, my only experience with valve stem seals was little bits of smoke at startup and after letting off and getting back on the throttle and i have tried to let off the gas (high vacuum) and re accelerating but i cant make it belch. If you drive at hiway speeds "sometimes" when you accelerate to pass it will make the sound and belch out the cloud. The intermittant part it is what has me thinking theres something else going on here.
