Oil burns nice and white
If it were valve covers, it would be in the engine bay area, not out the pipes. And it would be white smoke, and it wouldn't puff. You'd get a nice odor near the front of the car.

Oil does not burn nice and white. ATF burns whiter than Oil, and that's not very white either. Coolant is the whitest burning fluid in your car.
Oil has a darker grayish/blusish tint to it. |

I've had several cars with bad valve seals, and they would blow a light colored smoke out the tail pipe when started, after setting a while.
These are the seals on the valve stems, not the valve covers, so they let the oil seap down the valve stem into the combustion chamber, then upon starting, it burns off the oil that had leaked in over time, once that build up of oil burns off, it runs clean (this is to clarify, why valves seals will smoke out the Tailpipe). I'm not saying that it couldn't be coolent, but if it had a bad head gasket, or a cracked head, it would get Worse when the motor gets hot....

I do have a nasty smell after accelerating, like rotten eggs, but I think I've got a fried cat which is causing that. I don't know if the fried cat has anything to do with this mysterious "puff" of white smoke that i get. I love saying puff. How concerned should I actually be about this, if it is the valve stems? |

If it's the valve seals, it'll run pretty much forever like that, but it will burn a little oil, and could eventually foul the plugs, they can be replaced in the car, but the valve covers, and cam carriers have to come off, plus a couple special tool would be needed.., so it is a pretty in-depth undertaking if you're not a mechanic...but can be done.

Y'all lost me. Pipedream, you originally said the puff of smoke was coming from the engine bay, right? Valve seals leaking oil into the combustion chamber would cause a little smoke from the tailpipe.
Not that I have any ideas, but is this from a cold start? From whereabouts in the engine bay? dcb |

Just re-read the original post... And Valve stem seals will NOT cause smoke in the engine compartment, but can cause it to puff out a little smoke through the tail-pipe when starting the car.. I can't think of anything that will cause a puff of smoke from the engine compartment when starting a COLD car, other than an exhaust leak, and then your motor would have to be burninmg oil to smoke then... ....Ya got me...
