A lot of smoke at engine start up. Need help!

Hello all,

Well...my 68 Camaro (327/210) arrived and it was a beautiful day!
Of course I had to start her up, and noticed A LOT of smoke coming out of the tailpipe. It did clear up after idling for about 3-5 minutes.
Is there something I need to do to clear this up? Would an oil additive like MOA or Slick 50 help? Is it something with the carb?
Also, I want to change the oil in it so I am on my schedule...what type of oil do I use for this type of car? I have always used synthetic in my Jeep with Fuel Injection, but I have never owned a carbed car before. What do you guys use for your camaro's?
Thanks a lot for the help!

If the smoke goes away after a few seconds and things get to temp, it's probably worn valve guides.
You may want to do a compression check and leak down test, could have worn rings or a collapsed oil ring.
I use valvoline 10w30 and have never had a cam go flat, everything looks like new.
Don't use lucas or any other additives except for maybe something with more zdp (spelling). I used lucas once, when I took of the pan, alot of it was still stuck in the bottom like honey, even when added to a hot running motor.

The only Mustang I'd ever own is a Fender.

Re: A lot of smoke at engine start up. Need help!

If the compression is OK, and the valve seals are OK.... was the engine or car stored for a long time?
Maybe there was oil squirted down in through the spark plug holes to keep the cylinders from rusting if it was planned that it sit for a long time. That would account for the smoke as the oil was burnt off.
Plus it's pretty damn cold out.... the seals may be hardened and then seal up when the heads warmed up.

Re: A lot of smoke at engine start up. Need help!

What color is the smoke.White/blue/black?
White will be coolant leak or ATF
Blue will be engine oil
Black will be horribly rich fuel mixture.

With these cold ambient temps..could it be fogging/condensation that your seeing on a cold start.

If it cleared up after a few minutes it is probably just from condensation.

Do you have an automatic? Might be a trans vacuum modulator sucking up ATF to the intake,
or,
bad valve seals or worn valve guides on the cylinder heads.

Been store for a while..its just cleaning ot
If it does every time u fire up after sitting few couple hrs, oild leaks down past the guides
worn guides and or seals
pull a couple spark plugs...mark them which way the sit in the block
black on the bottom rings, black on the top giudes

SB chevs tend to wear 1st in valve guides ans seal around the 100K to 120K miles.
Doesnt do any damage just embarassing.

I say you were cleaning an old motor out. If you were leaking coolant you would have smelled something funny and it would have kept burning or pressurized your coolant.

Since it wasn't blue it wasn't oil and wouldn't be valveguides. Happy motoring!

A small coolant leak could close up with thermal expansion.Pull the plugs and look for one or more that appear to be steam cleaned.

On a cold engine in winter the condestion of normal fuel burn and moisture in the pipes will make the 'smoke' appear white.
As the oil from worn giudes burns off reasonbly quickly, the condestion will continue to puff out the back as white.
What is therory and what happens in real life are often 2 very different things.
