anyone ever do the seafoam treatment on their subie?

i do it to my Z by letting the vacuum suck it in through the intake after the car is up to temp. then wait 30-45 min and start it up and watch the smoke fly! it really clears up the engine and i was just wondering if anyone has ever done it to these cars. and if so, which hose did you use to suck it into the intake?

and if so, which hose did you use to suck it into the intake?

i did m ine threw the brake hose it worked good. i just let it suck in a little over half and ran it for like a minute then shut it off and started it again about 20 minutes later, it worked good. has anyone tried the transmission seafoam? its for tranys and power steering i wonder if it works good

Just don't put it in your PCV too fast. You'll kill the engine.

so just take the PCV valve out , start the car and pour some in? or can i pour it in the hose that connects to the PVC?

i would just use the brake booster hose its easier, i dont really now how to do it in the pcv valve hose

Just to reiterate what was said, don't let it suck in the seafoam too fast or it will hydrolock the engine. Kink the hose and make sure it takes at least 10 seconds to consume the can.

I've done it with many different products on several different cars, and Seafoam is probably my lowest preference because it smokes WAY too much. I mean, we are talking clouds that make it look like the house is on fire for 10+ minutes. My preference is either GM Top Engine cleaner or the Mopar Combustion Chamber cleaner, but those both require a trip to a dealer and are more expensive if you have to pay retail.
