smoke and idle problems?

[nburr20]

so went to the track today for jap nats took the car out at lunch for a spectator cruise, did about 3 laps of pushing to about 6,500-7,500 and smoke appeared under my bonnet came straight off and popped my bonnet i have smoke coming from my oil catch can and when not on accelerator it keeps wanting to stall, drove home, not reving over 3,000 seemed to run fine just had smoke coming out from behind me

anyone have any ideas what this could be

thanks nathan

I was thinking about this on my way home after talking to you, blue or white smoke? Maybe rings or HG, seems odd.

id say its more white smoke, i have fixed the idle problem or it fixed itself but still has smoke coming from the catch can

have you checked your oil at all?

yeah oil is 3/4 full, only topped up the other day

hmmmmmm, when i cooked my 4a(it stopped) i had white smoke pissing out of catch can, but next day(when returned to it on the side of the road) oil level was fine, white is normally coolant or brake fluid(wouldn't be this one)

Get a hold of a comp tester and test each cylinder. Maybe drop your oil and check for any sign of water in there.

It's probably your valve stem seals. I think I've got a dud one in my car as there is a little smoke taking off from lights etc. It happens so little I haven't got around to fixing it but its on the to-do list.
