If it's running too rich, you will get the obvious (darker colored) smoke, but it will also wash down the cylinders, dilute the oil, and start burning oil.
Long term results are heavy cylinder bore and top ring/groove wear.
Remember... a problem is just the beginning of a solution...
Keep us posted,

: Hi.
: I don't see any oil fouling on the
: plugs but they are black and soot
: covered. I have not done any tests yet.
: I did do one very smokey burnout, said
: some very choice words and parked the
: little bugger in the garage. I keep
: hoping it's a fuel problem like the
: webers are way too rich but I switched
: to the leanest set of main jets I have
: and it was no better. Maybe when the
: weather breaks I'll get some testing
: done or maybe I'll give Craigs list a
: try.

: Just a couple thoughts, keeping in mind
: the fact that the problem exists with 2
: different engines...
: An external top-oiler without a
: restrictor will fill the rocker box and
: let oil down the intake guides, but
: this will smoke worst under closed
: throttle.
: Crankcase venting properly?
: Have you done (dry)compression test and
: leakdown test?
: Are any of the plugs getting oil-fouled
: yet?
:
: Old Corvette??? Geez, that's what go
: tme into sports cars, After I trashed
: my '61 (in '71), my Dad OK'd my getting
: my first TR (4), he figured I couldn't
: get in as much trouble with a little
: 4-cylinder...

: Hi again.
: Here we go again. I've been driving
: the GT6 a bit this summer and it's been
: running great. I absolutely love the
: Toyota T 50 trans. Shifts crisp and
: smooth. Gear ratios are perfect for the
: street. My only concern was with the
: fact that I removed the AL.flywheel and
: it really hurt performance.. HOWEVER:
: Last week I noticed the exhaust was
: starting to become noticeable. Light at
: first but getting worse. Definitely
: blue. Spark plugs are black and sooty.
: At first it was only smoking when you
: take off from a stop. Now it smokes all
: the time and when you take off from a
: stop it's a fogger. Obviously time for
: some intervention. This engine only has
: a couple thousand miles on it and I
: don't think I can make myself tear it
: down again. At least not now. Can
: anyone give me a reason WHY this thing
: is going through piston rings? Two
: years ago I tore the engine apart twice
: because I couldn't get it to stop
: smoking. Reringed it twice and finally
: gave up and rebuilt a whole different
: engine. New pistons and rings. Bored
: .030 over. New cam and cam bearings.
: New everything within reason. Freshly
: rebuilt head with seals. New valves.
: How can this be happening again???
: Might have to give up and buy an old
: Corvette soon.
: P.J.
