1987 Chevy Monte Carlo V8 Automatic

I have an 87 Monte Carlo LS and I had a new carburator put on there, and its still failing the test. It failed the HC (ppm), and CO both were to high. Some people said I need my carburator adjusted and one said I need some new gaskets. And also my car is smoken from the tail piles real bad as well. Can you please help me out. Thanks

Hi:
If you purchased a new carb, there is a very good chance that it does need adjusted.

When you say there is smoke coming out of the exhaust, what color is it?

The smoke is white, but somethings it looks blue. So do you think its the oil, the reason why its not passing?

Is the smoke only there when the car is just started or all the time?

Yeap, sometimes it goes away. But for the must part it smokes. When im at stop lights, signs, drive throw. You think its the intake?

Hi Again:
It could be an intake gasket or a head gasket. I need you to check a few things. First, check the oil for coolant contamination, and the coolant for oil contamination. After that, check all around the intake for coolant leaks or evidence of coolant. FInally, and don't laugh, remove the PCV valve and with the engine running, take the oil fill cap off and let me know what happens to the engine (if anything) and if there is any smoke coming from the crankcase.
