I've heard positive comments about a product called Seafoam. Who makes it, where do you get it, how much does it cost, and when would I use it. It sounds like an aggressive gasoline additive. But should it be used on new engines with say 10K miles on them or so. If not, any other products you can recommend for routine maintenance of the injectors and fuel system.

 

Seafoam is an engine cleaner for the intake and fuel system. Orgionally developed for marine use. It is a liquid you suck into your pcv system to help clean up the valves and into the engine cylinders. It also goes into the gas tank to help clean up your injectors.

Very easy to use and effective. I seafoamed my 2000 5.4 with 37,000 miles last weekend and I have noticed an improvement esp on cold starts.

Find it a NAPA stores, $5 can. Use two cans. Cant wait to try it on my jeep which has 254,000 miles, 100,000 since a valve job.

How exactly do you go about sucking it into the PCV system? Do you stick the PCV hose directly into the bottle, or what? I found some at the local hardware store, I may pick a bottle up and do it. It doesn't hurt any sensors, does it??,,,,98

 

I've have a good friend that had a older Honda Car with high miles on it. I guess it was running very poorly. He heard about the seafoam and ran a couple of bottles through it. Said he could not believe the difference it made.

I have used it or something similar on a '79 truck I had with the I-6. I just poured some of it in the intake (after removing the air filter of course). I just used the bottle it came in. I think I dumped more of it out than into the tube. If I were to do it again, I think I would use a $2 spray bottle and spray it in.

I very serioulsy doubt it will affect any sensors in your truck.....

Good luck with it

This stuff sound interesting but agressive. Would you use it one engines with 10K miles on it? Or maybe just put it into the gas tank.

 

Still wondering how you are supposed to get it into the PCV system? Do you pour into the PCV tube, stick the hose into the bottle and let the the vacuum take it in, or what? I'm picking a bottle up today, so I need to know guys Might pick up two, one for gas tank, and one for the PCV system. Anyone know?? Either way it seems it would cause a check engine light to come on, because of the PCV leak. (Happened to me before when it was left unhooked by a Ford tech) HELP me out guys??,,,,,98

 

I unhooked the hose from the PCV valve and sucked the SeaFoam in from there. I brought the RPMs up and let the engine suck in in at a rate that caused the engine to bog down. I quickly shut off the engine and let it sit for the 5-10 minutes that the can recommended. Then when I started it up, there was a ton of white smoke. Don't do this in your driveway unless you really want to tick your neighbors off.

 

I'll be sure to do it in my driveway

 

I talked to my uncle yesterday about it a little. He says he uses the stuff in the aerosol can made by Seafoam called Deep Creep. He said it is more or less the same stuff, just in the spray can. The thing he was most amazed with the stuff is that it eats away at carbon so well..... Anyhow the stuuf in the can could help you spray it in there w/o the mess...

 

i used some seafoam trans tune and the trans is much smoother and doesnt slide into third anymore. thats another good product

 

Ford also sells a version of this that is safe to use..the instructions say to pinch off a vacume hose and adjust the flow so it sucks slow enuf that you hear the engin struggle but not stall then whe there is 1/4 or the bottle left you open the hose so it stalls the truck..let it sit for 20 min the go for a drive and open it up to blow everything that it lostened out.. smokes real good, kinda like something you would expect to see in a jamesbond movie
