I think your valvce guides are a little on the loose side. When the
engine cools down, there's enough clearance for oil in the head to drip
down an open valve and into the cylinder. On startup, voila - smoke.
Once the engine heats up, the head and the guides expand enough to keep
excess oil from leaking down the valves.
If you have umbrella valve stem seals, they may have perished by now,
and if not, installing a set would fix the problem.
We had a Toyota Tercel that had this very same problem, and I found that
on that particular engine the valve seals were a known weak point.

One more question for the resident wizards....
I notice that if I haven't driven the car in a week, when I start it
up I get a cloud of oil
smoke out the tail pipe. If it has been driven recently this doesn't
happen. I think
someone on this list may be sneaking into the garage and pouring oil
into a couple of
cylinders when I'm not around......
Cheers!! And thanks for all the good advise!
