Got a question for those of you who have run Sea Foam through the top of the motor. I just let the VX "sip" half a bottle of Sea Foam through the PCV tube after letting the engine get up to operating temperature. I turned the VX off and let it sit for, probably twenty minutes to half an hour. When I started the VX back up I didn't get ANY smoke like they warn you about.

I think the last time I had the throttle body and EGR cleaned was over 10,000 miles ago, so I would have expected to see some smoke because I'm sure there is some carbon build up in there somewhere. Did I let the Sea Foam sit too long? Should I give it another shot, but just let it sit for the recommended five minutes?
