I'm changing my oil and fuel filter tonight on my 7.3, Has anyone ever used Seafoam in there crankcase or used it in there fuel, I hear its good for carbon buildup on older engines.
2nd is their a trick to changing the fuel filter????

 

I had a buddy in Baton rouge that swore by Seafoam, He ran it in his oil and trans and powersteering fluid. He used to work on oil rigs and said that they ran Seafoam in all engines out in the gulf(Crew boats, Tugs and generators). His truck is at about 250k. My truck has about 220K, including 60k hard towing after Hurricane Katrina, and normal weekend towing of my fifth wheel. Mine is a 99.5 F250SD CC 4X4 and I have only run a fuel additive. I am a stickler about routine maintence, change oil every 3k when towing heavy, and every 6k when light .

Sooo, I guess to answer your question, If you don't have too many miles now then add it and let us know how it does. If you have a high milage truck I don't think i would add it ( you never know what that carbon build up is holding together)

just my .02

 

Ohh, As far as the fuel filter,Drain bowl by opening water seperator valve, use a 1/2 inch drive to take the cap off and then just pull out the filter, your new filter will come with a new cap, so don't reuse the old one, make sure you put the O ring on correctly when you replace the cap.

 

I've used seafoam with some (limited) sucess some of my other engines, but it's not the save all, cure all it claims to be. It's just one additive among many.

Works pretty well cleaning the crankcase, dump it in the oil and let it idle 15 minutes or so before the oil change. Don't dump it in and leave it as it thins the oil too much to operate with. Also makes a decent fuel addative, but it's not any better than plain old Power Service.

Use a oil filter wrench or spread jaws on a pair of channel locks to get the cap off the fuel filter.

 

anyone ever run the seafoam through the vacum line from the brake booster on their diesel? I have heard about folks doing on their gassers but never on a diesel, anyone know why?

 

dont do it on the diesel, the vaccum is formed by a pump, not the engine. you will probably blow the pump up

 

i dont think id inject it into an desile intake, thats how i always use it on gassers as it realy does a good job at cleaning carbon biuldup that way. i have torn down engins that i frequently run sea foam in by dumping it in the intake till it stalls letting it sit and soak for 15 mins or so and then restart the engin. it realy does do a good job at removing carbon. i wouldent use it in a desile this way however becouse i think it would preignite from the compresion, adding some to the fuel or crank case before an oil change wouldent cause any problems

 

thanks, I have been throwing around the idea of using it before my next oil change (I am pretty weary of magic/do-all potion-type stuff). Been doing a lot of looking around FTE for info and think I am ready to give it a shot in my oil before the next change. She has 315000miles to no telling how that oil is going to come out. I am running some through my fuel tank right now and it took the rough idle right out of my diesel. Thanks again for the help, I sure appreciate it

LOLOL this is why I ask around on FTE before poking around in my engine Thanks for the info

 

I use Seafoam on my motorcycles, particularly the ones that I haven't run for a while. I just use it as a gas additive. I don't think that a M/C oil supply is large enough for a thining additive. JMHO

like I said earlier, I am running some seafoam through my fuel tank. Usually my truck takes 3 tries to start....since the sea-foam it usually starts on the first try. I dunno if it was the seafoam but the seafoam was the only thing that changed on my truck in the past week. I am a follower of seafoam now...truly amazing stuff

 

So what is Seafoam and where would you find it for sale? I have never heard of it.

Eventually (pg2? 1/2 way down pg 1?) we start talking about how it actually works in the engie...hope that helps.

 

i guess that i have had a differnt experience with the seafoam, not so much personally but a couple of friends of mine put it into their crank case and did nothing but cause the motor smoke like a freight train. sorry these where gassers though i have never had it in the fuel but if it helps i might think about that hope all info helps thanks

 

Napa has it. I used to have the formula for making SeaFoam. The main ingredient is napha (Charcoal lighter fluid) and other goodies. I'll look through my stuff.

Seafoam works wonders on gassers that have a lot of crap in the carbs from setting. Back in the fifty's folks would run it straight into their outboard motors and let it set in there all winter. Spring comes, fires right up.

A fireman in Texas produced the makin's from the list that is given to the fire departments.
