How to use SeaFoam to clean your Engine – The RIGHT way!

Enjoy!

[MellowZ32]

great write-up Greg. thanks for clarifying some of the misconceptions I had about seafoaming.

[Hussain]

when should someone start thinking about using seafoam (around how many miles)? is 40k miles too soon?

[AZhitman]

Nope - That's perfect. Keep it clean in the first place, and you won't have issues down the line.

Also, I've found that using Chevron gas (Techron) seems to keep everything a LOT cleaner.

[Zero2Endless]

Sweeeet.

I remember sea-foaming my GTI LoL. Good times.

[Ellison@FCPImport]

Seafoamed my G35 when I first bought at 68k. Definitely worth it. Nice write up.

thank you!
people think I'm stupid when I tell them that you can really feel the difference between Chevron and cheaper gas.

[Kompresshun]

Thanks for this Greg! I always had a general idea of how to do it but I never really had a good detailed write up like this to go by, I need to do this to both of the cars soon. I used to do it about every 15,000-20,000 miles in my old Ranger and it really made quite a difference.

Someone who has seafoam'd their S13 want to post up a pic of the proper place to use from the brake booster line? It's been quite a few years since I've done it to a 240.

[breadbox]

I think I will do this right before next oil change.

[dre1507]

my rsx-s has 142xxx miles. i was thinking of doing this, but my oil is super clean right now. should i wait until it's time for an oil change, or just do it and spend the little it costs to change oil? or does doing it with clean oil mean i won't have to change my oil as soon?

[Dattebayo]

I seriously thought this was gonna be a joke about someone driving their car into the ocean...

[eds13]

thats because your retarded

Buy Seafoam Here!

ITS A SPAMBOT!!!

I'm still too scared to do it

[AZhitman]

Actually, it's an affiliate link to Amazon.com for a few places where you can buy Seafoam at a fat discount, and I think NICO makes like $ .03 on each can.

So, shut up and go order some Seafoam.

Ahh, suspicions confirmed. Clever man, and I appreciate your candor.

"Sipping" regular water via vacuum line leads to good results too. Buy water here!

[Mr1der]

takes too long. I'm gonna drive in a creek instead.

Will the seafoam help me shut up? Actually, I'm going to do this now Greg. I've been reading a lot of misconceptions and stuff. Glad you cleared it up. The vert needs some revival

[Chaotic_Warlord]

This might sound like a stupid question, but would this lead to old tired gaskets and seals to start leaking since it will essentially clean the gunk and build up that is possibly holding them together?

[AZhitman]

Nicely done.

No water here - I'd prefer something that, if accidentally over-ingested, won't hydrolock the engine.

Although, I did the water thing (in a pressure sprayer) on a LOT of carb'ed cars back in the day.

You're kidding, right, amigo? I'm SURE you could hydrolock an engine with seafoam...

[AZhitman]

COULD, but less likely. It's a petroleum product and supports combustion.

[Noxy]

Great write-up! My friend taught me how to use seafoam, but I always take all his advice about my car with a grain of salt... Thanks for clearing it up!

[Empty V]

Here's a video of the byproduct from Seafoaming my '01 QX4. This was from last sumer.

[Urabus GodofTraction]

COULD, but less likely. It's a petroleum product and supports combustion.

It's still a liquid! Even gas, without atomization of some sort, could hydro lock an engine. I bet the amount required to hydro lock an engine would be pretty similar between water, Seafoam, and gas.

I do like Seafoam, though. Some sloshing around in the Land Cruisers tank as we speak.

[s0m3th1ngAZ]

Yeah...had a buddy who bent a rod in his corolla using too much seafoam.

[troskinatior]

I dont get the "sipping" thing. Are you squeezeing the can of seafoam with the hose in it?

[AZhitman]

No. You're dipping the hose into the liquid and pulling it back out. Like sipping a soda through a straw, small sips.

There will be vacuum at the hose - You want it to pick up some Seafoam with the air.

[troskinatior]

aww I gotcha

[PoorManQ45]

Some of the Tribologists over at BITOG seem to think that Seafoam can break down the oil to a dangerous point. As in possible engine damage.

AutoRx carries a higher recommendation. It's a bit more expensive, but testing seems to show AutoRx removing deposits that were left after the recommended Seafoam treatment.
