Seafoam Questions

[SoLongStang9499]

Hey guys i would like to seafoam my 1999 ranger 4.0. I would like to run it through my vacuum brake booster line ONLY, I know my fuel system is clean as well as my crankcase. So my question is do i really need to change the oil after doing it to the top end of the engine? If i dont have any blowby, why would i need to? Would like some clarification on it, thanks

if you do it through the brake booster vaccum line then no, u wont need to change ur oil.

yep hes right. no need to change your oil. Be careful to do it in a well ventilated area, as it will smoke like cheech and chong...

Might wanna check your plugs afterwards though as they might be covered in all the carbon that once was caked throughout the intake runners, valves, and combustion chamber...

Why do you think you need to add Seafoam to the engine? shady

what the hell is seafoam? ive heard it on here before, but im lost. what is it for worn out engines? like lucas(but really works?)

It's for people who think a bunch of black smoke out the tailpipe means it is "doing something." As though anything one could do is a good thing....

If you have a carbon or sludge problem, you need more than a "good cleaning." It means something is broken. Even if that something is the owner (say, lack of oil changes).

And I've said this before -- even if it were to actually work and all that black smoke wasn't the seafoam itself burning and enrichening the mixture -- whatever gunk is removed from the cylinder must leave through the exhaust valve where it has the potential to make things quite a lot worse.

THE way to clean carbon from piston heads is (carefully) with a razor blade, and from cast iron combustion chambers is with a wire brush.

I agree with MAKG. The guys that have done this on here that I have read about have always had more problems afterwards. IMO if you have any problems that require taking off the heads clean the carbon off then. Otherwise change oil every 3000 miles.
Everybody see that guy who had over a million miles on a 1991 Chevy Silverado he got that by changing his oil every 3000 miles he kept up the maintance on it.

RESULTS:

Little to no smoke out the end, pick up seemed a tad bit better, not a whole lot. Did do something as i did create some misfires for a few minutes, but went away. I wouldnt say i was blown away, but it seem to run just a tad bit smoother. I had no problems prior to this and i have none as of now. For 3 bucks or whatever its worth a shot to try, didnt do wonders for me, but it seemed to help some. 99 ranger 4.0 80XXX miles

seafoam will always create a argument, its one thing i do from time to time on my trucks, some believe it works, some dont, its too stupid of a thing to argue about, if someone wants todo it then they will do it, if u dont want to ever try it, then dont, simple as that

With respect im going to have to disagree somewhat with MAKG. Yes the released carbon could hurt the exaust more than help, and yes some of the white smoke I was suppose to get is some of the seafoam burning. I did a test on a small flathead cylinder head to test what effects the seafoam had on the carbon. I put the head in an oven for 10 minutes to roughly 250 degrees, poured a small amount of seafoam on it and wait for 10 minutes, and as the engine is suppose to do, blow the mixture off, for this test an air compressor at roughly 25 PSI. The result was about 60-70% of the carbon was removed just with air. Would i say it works? Well I can say it most certainly helped, but it could have some very serious problems for an engine if alot of carbon exists. Their will always be skeptics, sometimes for good reason or just so they wont do it. I put gas in my tank everyweek, I use simple green to clean my house, I use windex to wash my windows, and i use seafoam to clean carbon. All chemicals designed for a certain purpose will often times work, but using the chemical correctly is where the trouble can begin. Thats my 2 cents, worked for me but may not others.
