Get the engine to make smoke...

Disconnect the PCV hose and plug the manifold...disconnect the vacuum modulator hose and plug the manifold port (if you have an auto trans)

Hammer it...*G* If you have an auto trans, shifting may be late because of the vacuum modulator being won't hurt anything though...

Engine may run a bit sluggish (rich) with the PCV plugged off but shouldn't smoke from that...

Tell us what you see and smell...
