Sea Foam

[jimnance]

I recalled somewhere here reading about a product called Sea Foam, used to help clean injectors. Anyway, my '05 had started to develop a slight but noticeable miss. I found Sea Foam at the local Auto Zone store. I added it to the fuel in the recommended ratio and before I was through 1/2 tank of fuel my engine was purring again. I've run about four more tanks of untreated fuel and she is still purring.



I like this stuff. Oo.

I don't believe in many things but this one made a believer out of me. I had a pretty good knock a few months ago and the wife and I were heading over to pigeon forge TN so I dumped 2 cans in the tank. By the time I got there, it was so dang quiet. That was about 8,000 miles ago and I have a slight knock again. Just picked up two cans today.

SeaFoam... ... ... . I used it in the 80s on the farm with my Dad, you may know how

farms are, lots of seasonal use equipment, often not run for months, sometimes

a couple of years go by before you use it again. Prior to the use of seafoam

It usually took an hour to half a day to get some of these engines running again.

Sometimes it took some new parts, Started using the seafoam and with proper

fogging of the engine, with the engine hot dribble in seafoam directly in to the carb till

it created a white cloud then pour it in till it killed, + some in the gas tank, engines

would start on the 1-4th pull even after 2 years of nonrunning, great stuff!



After My Dad Died in the late 80s I quit using seafoam, actually I quit doing alot of

things we did together, didn't even realize it till years later, and several junk engines

to boot. Some time in the early 90s I saw seafoam on sale and started using it again.

same great results as before.



I now though my business I maintain 50+ small engines

which is no small feat. I buy the seafoam by the case and have NO issues with all

the engines from 2 cyl chain and concrete saws to gas engines from 3. 5 to 20 hp

twins. The also make an aerosol version called Deep Creep. Much better for fogging

engines than the liquid + a host of other uses.



But can you believe it... ... . with cans of it everywhere... . I never once thought

to use it on my Cummins... ... ... . Doh!!!

That WILL change tomorrow.

Sea Foam in the Cummins?

I was over at the "bob is the oil guy.com",reading about the Sea Foam product & the way they recommend using is is to drain the fuel filter bowl, re-fill it with Sea Foam, reinstall the filter. After putting the rest in the tank, start it up & run the crap out of it until you're back to just diesel fuel.



To be honest, I'm a bit scared to do that to my truck for fear of damaging something by running straight Sea Foam through the fuel delivery system. Any of you guys done it this way & what were your results?



In the past, I've had some injector issues (knocking) that the dealer & DC would not fix. I fixed it with generous doses of fuel additive & Marvel Mystery Oil (MMO).



I'm a bit paraniod about injector problems & want to do whatever it takes to preserve them.



Thanks.

I have used it with great results in many vehicles over the years. My '90 rabbit diesel to start with. It works well in diesel fuel systems, at least in my experience. No adverse results. The rabbit got a regular dose and was running great with 165,000 miles when I sold it. My '01 Dodge reacts very well with a pint in the ff canister every filter change.

 

[jimnance]

I kind of did this once in my '95 CTD. I changed the fuel filter and forgot to have a supply of diesel on hand to prime the filter. I simply filled the filter with mineral spirits and then started the engine. I let it idle for a couple of minutes to allow the diesel and mineral sprits to mix before blasting down the road. No troubles.



I don't think I'd want to put a load on an engine with 100% of anything but diesel in the engine, but I don't think using Sea Foam as described would create a problem if you didn't put a load on the engine immediately.

 

[Windscreen]

I don't see how filling the filter bowl will really get you much more through the injectors vs. pouring it in the fuel tank. As soon as you key up, the lift pump fires up, moving fuel at a rate that could supply over 400 hp. The seafoam in the bowl will very quickly be diluted down and returned to the fuel tank.



Even if you key up immediately to crank, the fuel use at idle is very low, so the lift pump will end up putting nearly all of what you put in the bow into the fuel tank.

I actually used three cans when I did mine. I did dump the 2 in the tank and I did pour a can in the filter housing. I never thought about it being diluted so quick. It actually sounded better after those first few miles and after the long trip it was SO much quiter.



I will keep throwing it in every now and then.

An old diesel mechanic friend of mine turned me onto sea foam last year. We spent some time reviving my wood splitter which is powered by a 1933 Wisconsin 4 cylinder air-sucker. He recomended that I change the oil, add sea foam, run the engine for 8-10 hours and then change the oil again. It is amazing what it did for the engine. The oil came out blacker than anytihng I have ever seen. The bottom end noise has all but disappeared now. Seems to be good stuff. Anyone know what's in it?

 

[JRD]

Buffalo I did almost exactly what you are talking about and it turned out great for me. What I did differently though was I mixed about 80% Sea Foam and 20% Power Service for lubricity and made enough of this mix to fill the cannister. I dumped my mixture in the fuel cannister and then the rest of the can into my 1/2 tank. Took it out onto the main road and hammered it down for a few good bursts, unitl I knew I had gone through what was in my cannister. Runs smoother and what little knock I had, is gone. When I heard my injector knock, I ran out and got this stuff to fix the problem before it got out of hand.

What is this sea form stuff?

 

[MMcfall]

Been using Sea Foam for years in my boat motors for years - one can to 20 gal every third fill up - never thought to add it to any of my diesels. Tried two cans today in a full tank and drove from Tampa to Gulfport MS. Within 50 miles the engine was MUCH quieter - doesn't have that "ticking" rattle any more at all. Pulling off the Interstate down an off ramp I could hardly hear the engine running at all. I'll be anxious to see how long it lasts.

where can i get my hands on this sea foam stuff. i have never heard of it?? whats stores usually keep it in stock. ill have to give it a shot. i only have 13k on my truck but it seems to be alot louder then when i first bought it. also. my first diesel. how do you defiine injector knock to the regualar diesel sound. i cant tell, is it totally obvious or do you need trained ears to hear it?

Napa, Shucks, Car Quest, etc, etc.

Joe,

I have been doing it that way for years,just other brands I proved how well it works by doing before and after test with an opacity meter

I regularly use this now on my 2000. It has all but cleared up alot of rough idle problems I had. stuff is awesome! I, for the heck of it, dumped 2 cans in the tank last fall (full tank) just before jumping on the rollers... I wish I had thrown it in between dyno runs to see if there was a difference, but I put down 343HP and 768 Trq on just a Comp Edge, BHAF, and straight piped. Not to shabby.



Anyway, how many of you use it in the crank case between oil changes (been told to dump a can in 500 miles before an oil change)

 

[jimnance]

Obviously, it's got some pretty strong solvents in the product to clean up the injectors like it seems to. Personally, I'm not sure I'd put it in the oil. Modern Diesel oils have a pretty good additive package that should keep the inside of the crankcase in good shape. I'm not sure there would be a benefit unless you had stuck rings or something like that. For stuck rings I like MMO, though the Sea Foam ought to work as well.

Stopped by Auto Zone today and picked up two bottles of Sea Foam. I put one bottle in the tank (1/4 tank left) and drove around for about 20 minutes. Then I stopped at a fueling station and put the other bottle in, along with a half a bottle of Power Service and filled up. I drove up to the dealership where I bought my Ram, and about halfway there (20 miles) I noticed the truck getting quieter. This stuff works well.

I picked up a couple bottles at lunch at Napa, pricey through, about $7 a bottle, is that what it costs or just Napa.

 

[RPolidora]

I pay just a little over 5. 00 a can at advance auto.
