My AutoX yesterday was cut short due to my car producing big blue smoke clouds.
I drove out to the event and everything was fine. As I'm staging for the first heat, I shut my car down while waiting. I start it back up as I get close to the start line and I get some blue oil smoke, not much. One guy tells me it's probably my valve seals, and that it should clear up. It wasn't too bad for the rest of the first heat.
Fast forward to the second heat. My car was putting out more smoke, and towards the end it was so bad I cut my run early and parked it for the rest of the event. Once things cooled down, I looked over my fluids and everything was fine. I let it rest for the 3 hours till I left. for the drive home everything was good, and it ran fine today as well.
Other info- My car burns a QT every 500-700 miles, and when I had my plugs out, 2 of them looked oil fouled. Also, I recall something about running Neons 1qt low(?) for AutoXs due to oil control issues. Could that be the case? I just want to get this fixxed so I can run worry free at the next event in 3 weeks.
If you are burning that much oil, valve seals are most likely not the problem.
I had a 6 cyl Plymouth from the ice ages that would burn off the first quart and then no more. So I ran it at 4 qts instead of five.
Worth a try.
Hows this for a fix. Jeep at one time said if a customer had a similar problem to cut a piece off the dipstick tube.
I forget the exact amount, maybe 1/8".
I had a $125 1984 Olds Cutlass V6 that burned a quart every 125 miles - valve seals were shot. It coated spark plug #1 with oil.
I got on the highway and I would floor it and you would think I was driving some 1980's GM Diesel Car by the amount of smoke I generated.
Sounds like valve seals to me...........
burning oil usually comes from one of two sources... either valve seals, OR worn rings.
The easiest method of checking which it more likely is.... is to know when it is burning
burning during on-throttle, or acceleration = usually rings
burning on off throttle, or decceleration = usually valve seals
yes.. get it up to highway speeds one day and downshift and ride it down to idle.. if when you stop you get passed by huge plumes of smoke.. it is valve seals. The vacuume of downshifting will pull the oil out of the head into the combustion chamber
PCV system pressurizing the crankcase and blowing oil into the intake system?
500 to 700 miles on a quart doesn't sound like a ring or valve seal problem.
Look for other possible causes...
