Sea Foam

i did that to my 1990 nissan 240sx and it killed it. lol. for real. i heard a knocking noise like everything fell apart and it locked up. im now converting it to a 350 engine. made me kind of scared to use it on my mustang so i just pour it in the gas tank. good stuff nonetheless.

well went out last night and got a can, vidya to come on friday. neighbors have been burning leaves all week and its been pissing me off so its time to return the favor.

so i wanna take the vaccum line off the brake booster right?

You pull the line off the tree on the firewall. I believe its marked "S" on the tree. Its the main vacuum feed line from the intake, and is the fattest.

i went to advance auto to get a can thinking it would be 4, 5 dollars max, that stuff was 11.99 i just said forget it.

I don't remember it being that expensive... But maybe I wasn't paying attention last time I picked some up.

sooo i wanna take the end off the tree and keep it connected to the booster? sorry about all the questions, just trying to get it right

i took the line off the BB. apparently either will work.

I don't think you guys are understanding me here. There is a 3/8" ID tube that comes from the underside of the back of the upper intake that runs to the vacuum tree on the firewall. The nipple it connects to there is marked "S". Disconnect it from the tree on the firewall. Now you have a direct line to the intake manifold. There is no need to try to use the vacuum line that goes to the brake booster.

Important to note, though, you won't have power brakes while you're doing this, so don't try doing it on a hill!

makes it much easier, does the clamp just come off with pliers?

Yea, if its still has the factory hose clamps, its one of those crappy c-spring clamp thingamajigs. Pop it off with some needle nose pliers, and you could probably replace it with a standard worm-gear clamp if ya wanna.

well i just did it, was super easy, and smoked a hell of a lot. wish i could have found my camera

Its neat to run it through your intake but I think its more important to run it through your gas tank every now and again, that way it cleans out your pump, lines, and injectors, and gives your filter a break. I'd guess that it still has the same effect on your combustion chamber, just more slowly over a long period of time.

about half a can to a full tank?

 

[NIKwoaC]

about half a can to a full tank?

Yea, half to full. I think a full can is supposed to be able to treat up to 20 gallons. Sometimes I'll dump half in the oil and half in the gas tank after an oil change.

(Sorry I took so long to jump in here...)

If your car has over 150k miles on it and it's never been Seafoamed before, you might wind up with a smokeshow similar to this. (Bear in mind that this pic was taken during the SECOND treatment - the first was honestly twice as bad as this.)

EDIT: Also consider that if you're running an off-road X or H, you'll see WAY more smoke than you will if you have cats ... and the above pic was taken when I was running the stock four-cat H-pipe on my '86 GT 'vert.

CHEAP!!

i would do it BEFORE an oil change bcuz it thins out the oil and it's not good to have thin oil in are old cars..

your car looks exactly like mine..

Where have you heard that it thins the oil? I think if it had any malicious effects on oil, it wouldn't be labeled for use in the crankcase...

they say to put it in the oil so it will get in every crack and krevis.. whenever you add something as thin as that to something as think as oil it's bound to thin it out.. i'll give it a little test 2nite and find out for 100%.. i always put mine in like 30 miles b4 an oil change because that will break alot of gunk up and it will get caught in the oil filter and probably clog it up nice.. i'm just tedious and i don't like having that running in my oil that long of a time period..

That sounds pretty technical...
