Periodic completed in early Dec. on my -6A, by an experienced GA mech/pilot.
Flew the a/c 30 minutes to home base in MA.
Two weeks later, within 10 seconds of first (next) start-up, oily smoke
fills cockpit - had to quickly open tilt.
Continued for about 45 sec. to a minute, then the smoke ceased and hi-pwr
turn-up was fine. Shut down.
Waited about ten days ('til yesterday), fired it up again, same result. No
ramp drip. My mech is mystified.
I, personally, have not had this occur in 50 years of flying a/c of all
type.
Mech is now in FL for two months. Anybody had similar, with an idea for the
owner?
Thanks - George

First thing I would do is remove the cowling and investigate. If you
have not done this then DO NOT fly until you identify and resolve
the problem.

Yeah, thanks, Ron. My thoughts, too - - but it is rather cold up here, with
no hgr space. I'm sort of a candy-ass, as fingers begin to freeze.
I was hesitant to go through the drill, and then, being inexperienced in
mechanical work, to not see anything identifiable. I'm thinking I'd like
something to suggest to my mech (surprised he has no ideas....he's a good mech,
best
as I know). But I suppose I'll just have to get some locals experts to look
at it.
It's odd that it flew well from the NH "button-up" to here at my MA
base....but then began smoking. I guess one might have to suppose it very possibly
is
not related to the so-called annual.

Check the crankcase breather tube over the exhaust system. It may be soaking the
exhaust pipe with oil and burning off on start up. At idle power on the ground
you can get plenty of exhaust in the cabin.
Have somebody stand by when you start it again and see if they can detect any external
smoke. If it repeats itself, shut down and go look for the smoke trail
to find the culprit.

I'm not a mechanics , however, it sounds to me like you have an oil
leak which slowly accumulates a bunch over several days, then when you
fire it up, the oil creates the smoke until it is depleted. Could be a
leak internal to the engine example intake or exhaust valve (I would bet
on intake) leaking into the induction tubes and then being sucked into
the pistons and burned.

It may have taken that amount of time for something to develop. Find a
hangar, remove the cowl
and look for loose hoses, particularly oil carrying hoses. It may be
something else but without
looking, don't expect answers.

Thanks, Ed. I certainly agree with the slow-accumulation theory. I'll go
out with another guy, fire it up, see what we see from an external view.
Shouldn't be a biggie.
