I have searched Im I am quite skeptical about seafoam. I have a 95 runner. I have heard that is seized someones engine. I know you can put it into the take of gas and also into a vacuum line or intake. Can i get pictures of extactly where there at. I want to be very sure before i do it. thanks.

 

I've never heard of it seizing an engine - whoever that happened to might have done something incorrectly.

I do a seafoam treatment through the PCV to my 89 4Runner every other oil change and it makes a HUGE difference in throttle response and a slight increase in gas mileage. And I put a bottle in my gas tank every other oil change when I don't do it through the PCV.

Where in Az are you?? I'm in Chandler and I plan on doing my truck and 2 of my buddies trucks this weekend sometime, if you're local and wanna swing by for a Seafoam demo let me know.

 

The person that seized the engine placed the vacuum line INTO the can, and sucked way too much in at one time. You are supposed to lightly pour it inot the hose, not suck it out.

Remember you'll have to replace your plugs and possibly your O2 sensor afterward, since the treatment will probably foul them. Seafoam is sweet!

 

Will throwing a can in the gas tank work like putting it straight into the intake? Just not as strong I'd imagine eh?

 

Yep, it was a guy a 4x4wire member knew with a 4cyl Ford Ranger. Apparently he revved it up, SHOVED the brake booster line in the can, and promptly blew a hole in the side of the block.

As long as you do it correctly (slowly pour it in) there should be zero ill effects.

 

try picking a smaller vacuum line. The brake booster is probably the biggest one on your engine, just pick small, normal sized one and suck it in a little bit at a time. I have done this a 5 or 6 times and it works every time.

 

I've seen people say that but I think that's bunk personally...

I didn't see any mention of it on the side of the Seafoam can and I even seem to recall something I read there that contradicted this but I can't remember what it was.

I did a treatment about two weeks ago and my truck is running like a scalded dog. I ran half through the pcv line and dumped the other half in the tank when I was done. I just put my thumb over the pcv line and lifted it just slightly and poured the can over and it sucked it right in. The engine instantly smoothed out and the idle rose about 300rpms as it started cleaning. I usually don't buy into these snake oils but this one apparently works.

As for the plugs and sensors they're all fine. Do you really think anyone would buy this stuff of everytime you used it you had to replace $10 in plugs and a $150 O2 sensor?

I didn't change the plugs and I'm not going to either. They're fine.

 

Yea, some deposits collect on the plugs but they didn't need changing. A good cleaning and a wire brush takes care of it.

 

hmm every time ive used it i haveint had to replace or clean anything and it didint hurt anything made the truck run better

 

If you put it in the gas tank it works as injector cleaner, which there are better products for. If you put it into a vacuum line, and let it sit a few minutes before starting up it burns carbon out of the cylinders.

As long as you suck it up slow you wont hydrolock the engine. I've only ever heard of 2 people who managed to hydrolock 'em out of about 200 people who have used seafoam, and both of them just dumped the vacuum hose into the can of seafoam.When you do it you should also have someone sitting in the drivers seat giving it some gas to keep it from stalling.

I disagree with the whole plug and o2 thing. Last time this topic came up on here I got chewed out by people for saying that leaving the plugs is fine. I've yet to hear of anybody having issues with either, or anyone even changing their o2 after seafoaming it. If you think the plugs need to be cleaned take em out and clean em.
