smoke from breater to TB

Ok, heres the situation. If I have the vac line coming from breather connected to the TB the car will smoke like hell out of the exhaust pipes. If I remove the hose and plug it off. The car stops smoking. Whats the reason for this. I'm stumped. :shrug:

Tim is right. Which side do you plug (or both)? if you plug the oil filler, you should do something with the PCV (PCV flow is bi-directional - that is why that line is there). if you plug it off, you are bottlenecking the system.

good luck.

I actually just plugged off the oil filter. I was told that hose (valve cover to TB) is not needed. The PCV hose isn't pluged. I have ford motorsport valve covers.
the hose from the oil filler to TB is not needed if you run a breather (which is introducing unmetered air - that is why the TB to oil fill hose is there - metered air for a correct PCV).

if you have a means for air to exit and enter (breather, etc) then you should be alright.

good luck.
