That was amazing. I started the engine and slowly poured 1/2 a bottle of seafoam into the pcv vacuum line and waited 7 minutes. I started up the car, revved the engine, and a ton of smoke came out of the exhaust - I am surprised no one called the police.
I have a 1998 chevy venture with a new remanned long block engine that was installed 25,000 miles ago. I can't believe all that came from the engine.
