I added some Seafoam thru my vaccuum booster line about 2000 miles ago and I really noticed a difference in performance. I was wondering how often i could treat my engine with 200k without causing any damage to injectors or dislodging a bunch of crap that could bite me in the ass later on. Also, it smoked like hell and I was wondering if I added it to the gas tank if it would make my 62 leave a smoke screen as I'm cruising down the highway.Any input on frequency and the best application would be appreciated. :confused:

Where is the vacuum booster line?
 
That's what I call the large hose going from the power brake booster to the intake manifold. It really sucks the Seafoam in there.
 
I generally do sea-foaming once a year, although- I suppose you can do it once a week if you like. I don't know if it would dislodge a bunch of stuff into your engine or injectors.. probobly not.

As for adding it to the gas tank, you are supposed to do that- if you follow the instructions, and no- it doesn't leave a smoke screen following you down the highway, it's too diluted to do that.
 
I need to try the booster line treatment. I have done the gas tank treatment and there was no smoke.

WALoeIII... you can pick the stuff up at Advance Auto or any other good parts store. 1 pint cans, IIRC... about $5 a can.

jh

did you notice an improvement from adding it to the gas tank? i was thinking of doing this in the next week or so.
 
patride... I did have a smoother feel for a while. I did it a while back though, so I don't know if it is still "good" or if I might need to try it again (but I think I am still smoother than before the Sea Foam).

Even if it doesn't make your performance better, it will still clean up your tank and fuel system a bit. For $5 it wouldn't hurt to try it out.
 
thanks jason.

i'll give it a shot and post up on how it goes etc.

:cheers:

Also, when you do add it at the booster line I think you are only supposed to use about half a can. Then you can add the rest to the gas tank.
 
According to the directions on the can, they want you to add 1/3 to the brake booster line, 1/3 into your oil, and 1/3 into the gas tank.

I've never added it directly to the oil, doesn't seem like a good idea to add add a product designed to break down organic compounds to an organic compound. But, lots of people do it with no negative effects that I've heard of.

I add Marvel Mystery Oil to the crankcase instead. Milder cleaning action than sea foam would provide.

But I bet seafoam might actually clear up clogged oil passages if you had one.

Doc... me too. That just scares me a little, but I guess it works out... many have done it.

patride... no problem. Let us know.
 
Being that I work at a NAPA store, the SeaFoam rep came by when we started stocking SeaFoam. The process he used was 1/3 in the vaccum line, let set for 10 minutes then run on hiway, 1/3 in the fuel tank and 1/3 in the oil to remove water.
When added to the vaccum the directions say to be well ventilated because 'fumes will be extreme for a short time'. And the fumes will be extreme for a couple of miles when you run the engine.
Good luck,
Russ in Califonrnai :cool:
 
I had my truck idling the other night and added about 1/2 a can, maybe a little less to the oil, and there was an immediate change in the idle - it smoothed it out like you wouldn't believe. Didn't effect my oil pressure at all. I'll be doing an oil change here soon, so I'm not too worried about it - however, my engine is really dirty on the inside. I've been doing milder treatments (Marvel) for the last year and little by little it's gotten better, but still dirties up my oil pretty fast. Hoping to see better results with the sea foam though.

One draw back that could happen from doing the direct approach through the manifold, is all that carbon smoke could clog up your cat by overloading it - but I think it's an off chance, the Toyota cat is pretty stout and wasn't really designed to be replaced every 50k miles like American models of the same vintage.
 
i did it a lil while ago and did not really notice anything????ahwellll
 
Don't worry too much about it Al - I did it and didn't get much of a reaction either - that's actually a good thing. Means there's no carbon to burn off

a quick tip that might save you Sea Foamers a couple of bucks - I usually see it around for about $5-6 a can, but if you have a Northern Tools close by, they've got it for about $3-4 per can.
 
I added about 1/3 of the can through my brake booster line last night, the rest I added to the gas tank. All I can say is that the entire neighborhood must have though the truck was on fire. It smoked like crazy. I guess that I had a lot of carbon buildup. We'll see how it idles in the next couple of days.
 
Well guy's I just did this about an hour ago and everything smoked up pretty good when I did it through the brake booster line. Although I got a pretty good amout of smoke fron the tail pipe I also got plenty from the exhaust manifold? Is this supposed to happen also or does this mean that I have a leak in there somewhere? Thanks in advance.
