seafoam?
 

Hey guys, im new to this forum :bigbye: ..im usually on pelicanparts so go easy heh. anyone here use seafoam? pros/cons? good bad? everything they advertised? thanks

I do, its great, as advertised. i think my method is 1/3 in the fuel tank, 1/3 in the crank case, and 1/3 through the brake booster vacuum hose. I do not do it on my porsche (not the vacuum part) because I am afraid of some of the liquid routing through the diverter valve and sucked into the turbo. liquid hitting turbo compressor spinning at 120,000 RPM wont be nice.

I've heard that it works and it doesn't.

In a few weeks when I have more time, I'm going to take my spare Miata head and run my own test, just to see how well it dissolves the carbon. I'll take pictures and post the results. :)

k thanks guys. well i have an 84' NA so i dont have to worry about turbines and such...any suggestions on which hoses to use? cuz i heard that i could use any of the vacuum ones.

I've used it with mixed results. After using 1/3 of the bottle in the pcv line on my brother's e36, we couldn't believe all of the carbon that was coming out the exhuast. After using it on my escape, the carbon residue clogged up the egr valve which forced me to remove that and give it a good cleaning.

hopefully it works on a porsche the same way it works on the e36 haha..

has any used it on their porsches?

i heard...that it could possibly clog up ur cat pretty bad....

if you can modulate the amount going in, the brakes booster hose is convenient. If not, you don't want to suck in to much at once, find a small vacuum line, maybe pull it off the fuel dampner or something?

P.S. suck in at idle,(expect stalling out) turn off, let car sit for 15 minutes. Start it up, and drive it hard. (a few WOT runs works fine) the smoke coming out the back = sea foam working. Make sure and buy a cheapo set of sparks plugs for it, its not good for em.

ooo thanks eyal

which brings up another good point...that huge debate over platinum vs copper. i feel that copper is the best for these early 944's because they were made with the intention of copper. but many people think that platinum is good...what kinda of plugs do you guys run? (hitting winter here..andy suggestions on cold/warm spark plugs)

The stuff works well enough, but you’d much better off just removing the intake and swirlling some gasoline around inside of it and simply dumping out the junk. It’s a bit more work, but you’ll get a much cleaner intake and you won’t have to worry about putting all the excess carbon through your engine.

I agree with formerGMguy ... I used seafoam on my Honda (EGR system was clogged up). It did not help at all and when I removed the intake to really clean it out it was still completely nasty.

Use copper plugs.
They work just as well as the platinum (in every way that I can detect) and are far cheaper. That's what these cars were designed for, and that's what I run. I stick to Bosch or Champion copper plugs in my 951.
