I've read about running seafoam through the intake so I decided to try it today. At operating temperature, I removed the upper vacuum line from the plenum and attached a small plastic hose. With the engine running, I dipped the hose into the can of seafoam and let the vacuum suck out about a half a can (stopping preiodically as the rpms would fall). Smoked like an SOB but I'm sure my upper intake is clean.
PCV blow-by. When I had the plenum off last time it was coated with oil.
Hmmmmm, is it just oil or does the oil grab on to grit and so on?
Even though I am a suspension guy I build a few Ducati motors every year. They are a 1000cc twin with a 100 or 104mm bore (depending on what motor it is) which is pretty close to our piston size. I get a lot of crankcase pressure because those are some pretty big pistons flying around at 12,500rpm's. I run a breather box with a reed valve system that vents into the airbox. There is always a little tiny film of oil on the inside of the airbox. For years I tried figuring out how to get it to stop and never found a way. A few years back while in Italy I got a chance to sit down with one of the Factory Race Team motor builders and he said that their stuff is the same way. According to him there was no downside to such a little amount of oil and it may actualy be helping by keeping stuff on the intake side lubed up. He could have been full of it, but he did get me thinking.
I know, I know, useless point

I have 27K miles in my 06 GT. Should I do this or is this for cars with higher mileage?
Excuse my ignorance, but if you recommend I do this (I can get a can from Autozone) can someone show me with a picture which is the hose you guys are talking about and which end goes in the can of Sea Foam?
Thanks a lot.

Pull off the vacuum line labeled 5 put a small piece of rubber hose on the plenum. Start the car and route the hose into an open can. Suck up a little at a time, taking short gulps of air in between to prevent stalling. About a 1/2 a can is good. Stop the car and let it sit to soak. Reconnect the vacuum line.
