Oil Smoke, Accelerating, Right Hander

[Flintstone]

Taking a large roundabout enthusiastically the other day at about 3500-4000 rpm I noticed smoke in my rear view mirror.

Eased off, pulled over to check everything expecting to find some kind of spill of oil onto a manifold or somesuch but no sign. I'm not too keen on replicating it to see if the smoke comes from the exhaust (I'd have to have a follower to tell me) so what next?

Any ideas?

That'll be the tyres then?!!!!!!

Oil this time for sure.

If you'd just been doing a lot of high rev stuff, it could of been oil trapped in the rocker covers and a bit of oil being dragged through the breather into the inlet manifold and through the combustion process, hence a briefly smokey exhaust.

One of the problems we get on the race car is oil trapped at the top end of the engine after continuous high rev running, despite enlarging all the drains in the valley around the cam and around the pushrods in the heads, plus the drains added into the timing chest, its still happened once or twice.

Ok, understood.

I had also topped it up a few days before (with possibly a little too much) so perhaps this contributed. It doesn't smoke at any other time.

Are you positive it's oil smoke? Check for signs of tyre/body contact too.

The smell was a dead giveaway.

It's probably surge in the sump and now you'e lost some oil it won't do it again until you drive really fast

Oh, you didn't mention that before, you were talking about noticing smoke in the mirror. If you can smell it, I would guess it came from the engine bay. Perhaps a leaky rocker cover gasket, or something like that?
