There are a lot of people who swear by it, and most of the nay-sayers haven't used it - they just think it's snake oil or that it could foul sensors or hydro lock a cylinder (which unless you're pouring it in with a NASCAR style gas can that just ain't going to happen). I plan to Seafoam my 4.8L, it was a work truck and has 135,000 miles on it. It's actually supposed to help clean the cats, which I'm getting a possible failure on my right bank and also my oil pressure seems a bit high. From what I've read, the "full service" is to put 1/3 of the can in your fuel just like a normal fuel system cleaner (drive to almost empty then add the stuff and 10-20 gallons of gas), 1/3 in the oil (let it idle for 5 minutes then change your oil), and add 1/3 of the can through a vacuum line (depending on which one is easiest for you to get to). You can also get a spray bottle and pump it straight into your throttle body. I've heard of people doing a full bottle in each, but I'm probably going to go 1/2 fuel 1/2 oil and use 1/2 a can of spray.
Some people say to drive it for 15 minutes with it in the oil, and I've heard of people just leaving it in for 500 miles or more. It's oil based, so it may not hurt anything - but I plan to change the oil/filter to get rid of any gunk it stirs up. I also plan to change my spark plugs, wires, fuel filter, belt,and the O2 sensor on the right bank rear of the cat (nobody told me we have 4 of the stupid things!). If all goes well we're going to do the same to my '72 - seafoam claims it can help unstick your valves and the old 350 seems to need some help there.
If you go straight to the intake make sure you're in a well ventilated area, it may very well smoke. , and GM even makes a "top end cleaner" that seems to be the same type of stuff. You could go with that if you aren't sure of the seafoam, there are plenty of people (even non-GM types) that swear by it, too.1972 350 GMC Sprint (under construction) :whip:

I use the vacuum line to the brake booster, but on those cars that don't have vacuum boost, I use any line that has good vacuum. I don't usually add it to the oil, mostly because I don't do my own changes and I forget to add it before the drive to the shop. I dump a can into the tank every 4 months.There is no way to happiness....happiness is the way.:yipi:
