I have used Seafoam on my 91 ford F150 on the 4.9L inline 6 and it seams to run smoother after I do it. I pull off the vacuum line and suck a 3/4 a bottle down the intake and pour a 1/4 in the crank case, and another bottle in the gas tanks. It smokes like crazy, but then i drive it, fairly hard for a while, and it cleans it right up. I then change the oil, to get whatever gunk came out from putting it in the oil. Does anybody else use Seafoam? The only other vehicle I used it on was my 80 gmc with a crate 350 in it. fun truck to drive!!! Does anybody use it in their AD's??? Any advise on using it or not using it? Just curious
This is 100% "hear say" and may not be worth the time it took me to type this or you to read it, but: I have heard that Seafoam is a great additive for gas if you don't use something on a regular basis. However, I've heard that if you have lined your tank with a sealant to inhibit rust, etc, it will eat away at it and pretty much muck things up. I use "Sta-Bil" in everything I have that uses gasoline from lawn mowers to '50 Chevy PU's to outboard engines on boats if I don't use them on a regular basis. I am "sold" on that stuff. My brother-in-law, the M1-A1 tank mechanic swears by the stuff! (But then again, he married my sister!)
thanks, I will take a look at that stuff. I definitly don't use it on a regular basis, just once a year or something like that. I was just curious what anyone else thought of Seafoam. I guess its my nature to wonder
SeaFoam For Gasoline Oh yes , it's VERY good stuff ! I highly recommend it . It won't clean out any dirt but it absolutely dissolves and gum or varnish deposits from sitting of from bad gas . They make sveral different products , follow the label instructions and don't get clever , you'll love it . Be aware that SeaFoam will turn the element in glear plastic fuel filters brown , I always replace them after dosing with SeaFoam . FWIW , cleaning the accumulated carbon deposits out of any old tech engine , will always make it run smoother , stop dieseling , eleminate knocks and pings.... You can do this by _fully_ warming up the engine (means : DRIVE IT . not idle in the driveway) then remove the air cleaner and hold the throttle to 2,500 + RPM's and use a pump sprayer filled with plain water to enter a fine mist into the carby ~ the water mist , when it touches the hot piston crowns and combustion chambers , will instantly flash to steam and blow all the carbon out, you'll see the grey/black cloud coming out the exhaust . DO NOT let some dufus talk you into simply dribbeling water out of a cup or bottle into the carby ! this can cause hydro-locking and since the engine is hot and running at speed , something has to give , usually it's the piston that cracks but occasionally yuo'll get ' lucky ' and bend a connecting rod so DON'T get cute , follow the instructions ! .
Sweet I will give that a shot. I know it always seems to help out my old ford. It for sure helped out my 350 chevy. When it tried to "diesel" I knew it was time for some seafoam, and it must have done something, i would like to think it cleaned it up, but it didn't do that after I got done. Thanks again, I was just curious to what people thought about the stuff. My father in law swears by it, and i have had good luck with it.
Brian, Brian, Brian!!!!!! Send that part I sent you BACK!!! And WASH OUT YOUR MOUTH!!! Such language on a GM site!!! You keep dropping the "F" bomb like it's the word "the"! P-L-E-A-S-E know that this IS a no-no on this site! If you MUST say that name, something like, "f@#*" is usually permitted. Anything else is like a vampire seeing sunshine when our eyes roll across a post and find that someone actually wrote that word in it's entirety! It's only because your a friend of mine that I tell you this.
