So the other day I removed my hard ac lines. The condenser and the ac part in front of the radiator underneath the ac tab near the front of the motor now the car smokes white real bad while driving any ideas? I left the compressor on until I get a belt but I forgot to plug in the sensor closest to the firewall on the intake manifold but could the ac cause a smoke I plugged it back in but it still smokes.

 

Where is the smoke coming from? Maybe u got compressor oil on the header.

 

Exhaust white smoke a ton of it while revving

 

Thats a weird issue.

 

If the white smoke is coming out of the exhaust pipes I don't think it's related as it may be a blown head gasket. Have you put any additives in the fuel tank recently ?

If the smoke is not coming out of the exhaust pipes but just from under the vehicle it could be compressor oil spilled on the header/exhaust system like mentioned above.

 

Strange thing was I been driving the car and I'm 100 sure it did not smoke the day before I also removed my catch cans the same day and returned the line from the Pcv valve back into the intake manifold and put a breather on the other line that should have lead back into the intake could that be the problum? I plugged the hole in the intake.

 

I don't think so by the description but if your engine is ingesting excess oil through the intake that could be a cause of the smoke as well. Maybe there is something allowing fluid into the intake system. With a blown head gasket the white smoke would smell very sweet, and much like coolant, you couldn't mistake it for anything else. If you are burning oil it will have a very different smell, quite sour, I'm sure you've smelled burned oil. Get someone to rev your car while you get a whiff of it and see it blowing out the tailpipes.

 

are you revving in neutral while parked or do you mean while you're driving? (and you see a ton of smoke in the rearview).

If it's the latter, I'll bet that you forgot to plug up the AC line that has coolant running through it, and while driving it's finding it's way onto the exhaust manifold and you're seeing it behind you in the rearview because there's nowhere else for it to escape/be seen.

 

ac line that has coolant running through it? what?

 

It looks like when I route the hose on the valve cover back to the intake pipe the smoke goes completely away. When I plugged the hole on the intake and place a filter on the valve cover the smoke comes back on and it's white smoke out the tail pipe while revving and while driving. Why is this?
