Love it straight to the point and simplified
J - Thanks for the feedback! We hope it helps.
Have high mileage Mustang 302 and it suddenly started blowing a couple of seconds of blue/gray smoke after interstate driving for at least 15 minutes. When I exit interstate, decelerate and then merge onto regular road and accelerate in 2-3 gear, it will blow a couple of seconds of blue/gray smoke and then clears up. I can drive in city, idle fine, runs like a top. I just did a complete tune-up and resealed engine and there are no vacuum leaks and the car runs beautiful except for the occasional smoke after high speed driving. I did take out spark plugs and only 1 plug was a greasy/oily mess. I think the oil is getting sucked up through the upper manifold via the pcv valve and then sent to the combustion chamber during high vacuum driving(interstate). Would a bad valve seal on that one cylinder that has an oily spark plug have a bad valve seal. I don’t think it’s a bad piston ring on that one cylinder, but I could be wrong.
What do you think?
J - I think your diagnosis is spot on. There has to be oil coming from somewhere that is going into the combustion chamber.
I’m doing a compression test this weekend and that could tell a lot.
Do you think replacing the valve stem seal on that cylinder that has the nasty spark plug will/could fix the problem?
J - Wait and see after the test, but it certainly could!
sounds just like what i have going on.. Especially letting off the gas on a down hill , the next light it blows a cloud..
Cold start for about 5 seconds then it's gone
