Panzo Posted April 12, 2016 Share Posted April 12, 2016 Has anyone tried to sea foam the 2.5i h4? I'm having a hard time finding which lines to use, also would anyone suggest how to proceed? If maybe the spray format is better? Thank you! Link to comment Share on other sites More sharing options...
Perscitus Posted April 12, 2016 Share Posted April 12, 2016 There are a few 'flavors' of Sea Foam on the market today. Some better for intake manifold applications, vacuum lines, or in-take use. Personally I would give something else a try first: Berryman B-12 Chemtool (15 oz can). Readily available @ local WalMarts. https://www.berrymanproducts.com/products/gasoline/b-12-chemtool-carburetor-fuel-system-and-injector-cleaner/ http://www.walmart.com/ip/B-12-Chemtool-Carburetor-Fuel-System-and-Injector-Cleaner/16817404 [ame=http://www.amazon.com/Berryman-Chemtool-Carburetor-Treatment-Injector/dp/B000CCMNAG]Amazon.com: Berryman 0116 B-12 Chemtool Carburetor/Fuel Treatment and Injector Cleaner - 15 oz.: Automotive[/ame] http://www.fuelinjectorcleanerhq.com/berryman-b-12-chemtool-carburetor-fuel-treatment-and-injector-cleaner-review/ Link to comment Share on other sites More sharing options...
dgoodhue Posted April 12, 2016 Share Posted April 12, 2016 Do you think you have carbon deposits? Link to comment Share on other sites More sharing options...
JLGT Posted April 12, 2016 Share Posted April 12, 2016 Another good brand is https://gumout.com/multi-system-tune-up/ looks like seafoam but better since it has P.E.A. in it. https://gumout.com/gumout-science/ I just throw a little in the crankcase right before an oil change and the rest in the tank.

jojorios Posted April 12, 2016 Share Posted April 12, 2016 Not to thread jack, but I've always wondered about this. How is this done on the LGT? Link to comment Share on other sites More sharing options...

ripstik Posted April 12, 2016 Share Posted April 12, 2016 Not to thread jack, but I've always wondered about this. How is this done on the LGT? the spray in would go in the intake track after the intercooler, there may be an issue with it stalling out because it does cause the engine to run like a tractor for a minute but i doubt it will be problem since you won't be in boost till this stuff is long gone and the MAF should still get a relatively good reading, I'm not sure what kind the OP is using though. FWIW i absolutely love seafoam and have used it in my boat(s) and drit bikes, quads, lawn mowers for years and have never been upset with it. and after seeing the test that chris crash on you tube did i definitely stand behind it. never felt the need to do it any of my cars though because i never saw any symptoms of carbon build up in them.

gimpydingo Posted April 12, 2016 Share Posted April 12, 2016 There are quite a few posted buried in these forums regarding seafoam and other products. I've read a lot about this and reviewed a ton of videos. The seafoam seems to barely remove carbon deposits, but most tests with scopes are only done once and not over several months or a years time to see if it helps more over the long term. Seems the results are about the same as spraying water into the system and "steaming" the pistons. Doesn't really seem to hurt anything using through the brake booster, etc... I wouldn't recommend throwing it into the oil though. While I haven't use seafoam to clean the deposits, I have run it through my fuel tank as well as Berrymans B12 and MMM. I logged some crazy knock when I used the B12, could have been bad gas??. I did just put some MMM in my gas tank last fill up. I'll use that maybe every 5 - 10 fill ups.

08SpecB_DE Posted April 12, 2016 Share Posted April 12, 2016 CRC One Step is the bees knees. Use it at your own risk but it's 10x better than seafoam. Be prepared to replace your sparkplugs afterwards. Its the best bang for your buck product on the market. Link to comment Share on other sites More sharing options...
FLlegacy Posted April 13, 2016 Share Posted April 13, 2016 So in theory a water/meth injection system could keep the engine cleaner? Sent from my SAMSUNG-SGH-I337 using Tapatalk Link to comment Share on other sites More sharing options...
Perscitus Posted April 13, 2016 Share Posted April 13, 2016 Yes for port and port/direct injection engines, not so much for DI engines. For those periodic wallnut blasting, EGR deletes, catch cans can keep intake valve and manifold gunk at bay longer. Link to comment Share on other sites More sharing options...
dgoodhue Posted April 13, 2016 Share Posted April 13, 2016 If you ran methanol or water regularly, it would keep a direct injection clean as well. You couldn't just add it to clogged intake and expect instant results. Link to comment Share on other sites More sharing options...

apexi Posted April 14, 2016 Share Posted April 14, 2016 I know this doesn't answer the OP's question.. But Red Line si-1 is also pretty good in my opinion. I took some videos of the results below with a borescope. http://legacygt.com/forums/showpost.php?p=4954670&postcount=96 Link to comment Share on other sites More sharing options...
Panzo Posted April 14, 2016 Author Share Posted April 14, 2016 I completed the treatment with the spray format sea foam it was a breeze, no need to remove maf or anything like that, not much smoke though, guess there wasn't much carbon buildup at less then 60k good idea to do so in preventative manner as to avoid problems in the long run. Could not find any of the other products discussed here as I live in Canada. Link to comment Share on other sites More sharing options...

HMM, that's strange, the smoke isn't really from the carbon as much as it from the product itself. did you empty the whole can? Link to comment Share on other sites More sharing options...

I may want to run a can thorough my Subaru before I do my 60k mile tune up as preventative measure. I have had a few engine apart and have only found one that had carbon build up @110k miles. I bought a used Chevy Prizm with 52k miles and that car pinged on 87 which 93 octane would cure the detonation. Sea foam thankfully resolved the issue. (I didn't buy a economy car to run 93). The 2 commonalities between those two engine with carbon issue is the prior owners were women, I wonder if they were babied to much. I kept the Prizm for 80k more miles and never had another pinging issue. Link to comment Share on other sites More sharing options...
