Is my engine F'ed??
Is my engine F'ed?? I went to start my car the other day and when it cranked it was smoking like a freight train!! It looks and smells like the car is burning a lot of oil. It had been smoking a little bit just after startup like the valve seals were bad but now it is a steady stream of blueish tint smoke. I had just changed the oil the day before with Mobil 1 5w-30. I decided to take the car for a spin thinking it would clear up, that maybe it was just oil in the intake from blowby. The car drove fine for about 6mi.and didnt really smoke on the road. Then out of nowhere it started Reving up by itself (rpms going up and down) and the car started smoking like hell, sputtering, the check engine light started flashing and for a few seconds it made a screaching sound and the car wont stay running unless you keep your foot on the throttle. The engine is only a year old w/ 7K mi, and ideas on what would cause this? Any input is greatly appreciated
Is the car hot when is starts acting like this? Blue smoke sounds like head gasket (water mixing with oil). Minus the smoke...some cars act like that when they run hot. Check to see if your fans are working or if your thermostat is bad. If you blew a head gasket that may be the root of your problem.

The thing is the car is not running hot at all and it smokes all the time as soon as its started. Ive checked the oil several times, im sure ive drained all the old oil and its fine with no sign of water or gas and is sitting in the crosshatched area on the dipstick.
DaddySS, someone else was saying it sounds like a vaccum leak. By disconnecting and plugging the pcv do you mean completley removing the system?
Thanks for the input fellas, keep it coming

What color is the smoke? The color will help determine the problem. Have you checked the plugs? For the RPMs going up and down, is the car in gear or in park? If the check engine light has come on, then codes have been thrown. What are they? If you do not have a OBD2 reader, you can get the car scanned at Checker, AutoZone, etc for free. The codes thrown will be very helpful.

Verdad Gallardo I just started it up and its not smoking as bad as it was but its still smoking quite a bit with bluish tinted smoke and it smells like the car is running rich unlike the other day when it was running the exhuast only really smelt like oil. I havent had a chance to remove the plugs yet, and i really dont want to drive it all the way to the parts store to get it scanned, i might trailer it up there.
when the engine was built the rings were gapped for nitrous and may have been gapped a little wide, i believe it was .022 on the top ring and .027 on the bottom would this effect the longevity of the rings??
