Did you use WD40 or something like that? even the slightest amount of it on the exhaust manifold would make it look like it'* smoking.

Take another look after it'* been running for an hour or so.

I got his original message all wrong.... I thought that smoke was coming out of the spark plugs

I've missed a lot of sleep in the last couple of days... I promise not to waste any more bandwidth until I get a good night sleep

Sounds like you screwed something up BUD. I would get a compression test done as stated before... its the only way to tell if one of your cylinders is dead and pushing oil into your combustion chamber......

also check your valve cover gaskets. if those leak it could be dripping down onto your exhaust manifold and burning.

Your car has always run hot too hasn't it? You replaced the plugs wires and coils too.... A head gasket might explain why you think your car runs like a tortoise. Lets race!!
