well i just went out and bought myself a can of Seafoam, i have yet to use it, i have a couple questions first.

it says that when using the throttle body or vacuum line to only put in 1/3 of a can? doesnt that seem a little low? its a 16 oz can...

it says to feed 1/3 can into a warm,running engine...turn it off, wait 5 minutes and then turn it back on...then it doesnt say what to do after that...am i done?

i plan on changing the oil afterwards, because its that time anyway..you think it would hurt anything to use the whole can? or to use the directions for the GM top-end cleaner instead? isnt it basically the same thing?

thanks for the input that will soon follow

I've only run seafoam in the crankcase and the fuel tank. Never tried running it trough the top end. It wouldn't acutally run through our throttle bodies any ways because we have a dry intake set up. Can't get it to go into the TB anyways...

yeah id only heard of it being run through the gas tank as well, but this can is the "multi-use" formula or something like that, and it says right on the can that you can either use it in throttle body.vacuum lines or a carburator....you can also put it in your oil but i dont want to, any other thoughts?....also what if i put the 1/3 of a can through the top end, then dump the rest in the gas tank?

id stay away from it i seen people come back with spun bearings i wouldnt suggest over 120,XXX miles on a car

well i put in about 2 inches worth of the can through the vacuum line...shut the car off as directed...then will i was waiting the 5 minutes i decided to pour the rest in with the oil..i started it back up after 5 minutes and revved it some and drove it around a while in the yard(i have a big yard)...then i shut it off, changed the oil and started back up and all was well...during all this time i didnt notice any black smoke or really much of anything, so i figured i didnt hurt anything, but i didnt help anything either...just for kicks i took it for a test drive....lets just say i didnt spin any bearings, but i did spin some tires

i live on gravel so i took it down to the low-water bridge, where i can usually only get a little scratch on such a night as this (foggy, 40s) and it spun pretty hardcore..so im happy with the results...ill be able to open it up on the highway tomorrow to see what else is new

I've only used seafoam on hi mile engines and never once had a problem...>But I've never sent it in the top end....My oil change is comin up, so I'm gonna dump a can in the oil in the morning and maybe do the top end cleaner this week....before I go out to rock falls with a couple of guys from BC this weekend. Get'er nice and clean before I **** pound it for a day at the track.

Ummm....not sure what you're talking about. I don't think I've ever heard of a spun bearing as a result of seafoam use, especially in the intake/vacuum line. It doesn't have any direct path to the lower part of the engine, so how can it spin a bearing?

Use the Seafoam products as directed, and they won't damage your car. If they did, we'd have heard about it. I've used Seafoam Trans-Tune in the past with great success.

did somebody say transmission cleaner? hmm.. I could use some of that stuff. I need to look into their product line.

I don't know if you want to do that, it might be a similar idea to a flush... since our cars are old stuff, the gunk inside may be what'* holding up and preventing leaks

If your car'* tranny has been regularly serviced and flushed in the past, gopher it, I guess?

mines been flushed, but the accumulator? [thing that pumps fluid to gears to the individual gears or whatever] are really not the way I want them to be. Reverse when cold.. is just ugh, nothing you want to see. And, it probably wouldn't be too bad. The fluid was serviced at 75k, 115k, and 145k [4 k ago], but it was never flushed in that time, just drained and refilled, which gives my fluid a nasty pink colour, and my car shouldn't have pink! Cleaning the tranny, could only be good for me.
