Anyone Seafoam?
Anyone ever use seafoam in their 2.8L V6? I've got two cans of the stuff laying around and was thinking about using a can on the 88GT. When we did a buddies civic, the civic forum said use 1/3 (of a container) in the gas tank, 1/3 in the vacuum system, and 1/3 in the crankcase. Then run it through for a little while. Change the oil, and change the plugs. My conventional oil has been sitting in the car for 4 months now, so I was thinking about changing to synthetic anyways. However I have heard seafoam can mess up the O2, and mine is new, is this true? Also pep boys sells some heavy crankcase detergents, they say pour it in, run for like 6-8 minutes, then drain the oil out. Would that work better than seafoam? Car has 92,000 miles, I am going to change the oil soon, I've got a brand new set of NGK UR5s laying around, and I have a spare can of seafoam. Thoughts?
Also, if I do seafoam, which vac line do you guys like to use?

just started using it last year. love the stuff.
carefull running it thru a vacuum line - it'll suck the can dry quickly. make sure you can restrict it's flow. and, be ready to goose the throttle. it'll smoke for awhile after the can is empty too. I've never used it in the oil, since I use synthetic, and its always clean anyways.
I dont doubt that you can "coat" the O2 sensor in soot. hasn't happened in either of the cars I've used it on tho. one was 130k car, getting a cleaning for its first time. sure smoothed it out tho. gave it 2 cans. first one sucked thru with intake vacuum. then a week later, poured one into the fuel tank.
a good choice for a vacuum source would be the brake booster port. but - being as big as it is, make sure you can restrict it. it the 1/4"-3/8" hose coming out the back side, and then going straight down. has a clamp. just pick this one, because its one of the few accessable on the Fiero intake. or - get a misting bottle, remove the rubber snorkle, and just mist it in thru the throttle body. benifit: this will also clean the IAC

Well should I be worried about it permanently damaging my O2, or will it clean itself off in a short time? I think I am going to give a can thru the motor (I did half a can in the gas tank a while ago) and use some detergent in the crankcase. I want to keep the 88 getting 30mpg and running for a long while.

The guys in the Crown Vic Police Interceptor crown practically worship the stuff. But considering that most police cars spend alot of time idling and building up carbon, I would imagine that the results must help alot for them.

I've used it several times in the past without a hitch, assisted my neighbor with the stuff and his truck hasn't stopped smoking for the last year.
Moral to the story. If gunk is keeping it from leaking..... it won't any more. He used it in fuel, oil, and we used it direct through the throttle body.

I have not had this happen. but, only had 2 cars to go by. and, one of them burnt oil - so I only went to synth blend, not full synth.Kohburn wrote:if you have a high milage engine thats always had conventional oil - detergents and switching to synthetic is almost a guaranteed way to make it start leaking.
but, I understand why. if there are existing leaks, but they are goo'd by dino slop - the synth will clean that goo out and expose the leak. it DOES NOT create new leaks - it exposes existing leaks. the existing leaks are just sloooow due to the goo.

well, if you look at the Seafoam vs GM TEC - you'll see they are the same thing. either way - good stuff.whipped wrote:seafoam is a ripoff for what it is. You can get the same results by running water through a vacuum line.
For "better than water" cleaning, I would suggest GM's TEC (top engine cleaner).
Oh, and DON'T put seafoam in your engine oil.
and - yes - H2O is one of the finest carbon breakers there is.
edit - just check more into this - yes, GM TEC does have an extra ingredient. but - still mostly Zippo lighter fluid.
Umm no, they are not the same thing.Pyrthian wrote: well, if you look at the Seafoam vs GM TEC - you'll see they are the same thing. either way - good stuff.

Seafoam ingredients:
Isopropyl Alcohol (rubbing alcohol), pale oil, and naptha.
GM TEC ingredients:
2-BUTOXYETHANOL, naptha, 4-METHYL-2-PENTANOL, 9-OCTADECENDIC ACID
GM isn't making money selling snake oil (rubbing alcohol and lighter fluid), they designed their concoction to break down carbon inside combustion chambers better than anything else.

yes, I've used kerosene like that for a long time - untill I wrecked a oil pressure sender. but - nowadays - just switch to synthetic - and it'll slowly clean itselfKohburn wrote:all the old schoolers say to stick a quart of ATF in the oil and idle it for 10 minutes then drain all your oil out and refill with new - supposed to clean all the buildup out.
