2003 cadillac cts - white smoke after replacing spark plugs

I have a 2003 cadillac cts and my problem is that, as soon as I replaced my spark plugs and turned on the car, there was a huge cloud of white smoke coming out of my exhaust, I did have a LOT of oil in the spark plug tubes, I let the oil go down by taking the spark plugs out, how can I make this stop?

Oil leaking on engine smoke coming into car.
Check that the valve cover gaskets are leaking. If they are, then replace them.
Also, check where the oil is coming from and replace any seals or gaskets that are
causing smoke to come into the car.

I have an cadillac Cts 2003 with starting problems
the plugs are the problem, they become unable to ignite all the fuel when in idle, so that they get wet and won't give any spark until dry. try to replace them. if there's no difference the problem is at the admission system(fuel pump maybe)

My 03 cadiallic cts has 98,000 miles i was wondering, when is it time to change the timiming belt,and spark plugs
Cadillac recommends it be replaced at 100,000 miles.
You should also consider changing the tensioner (1) and idlers (2) at the same time. A kit is available from the dealer and various aftermarket sources that contains all the parts.
I hope this answers your question.
