Mkd55: [you] decided to comment in rebutal with other forums members opinions and experiences with seafoam.
Nothing wrong with that. I commented on what I though were some invalid assumptions and attributions related to posters use of SeaFoam. Posters expressed their comments about my tests and conclusions. Nothing wrong with that.
Mkd55: and probably don't share your views on the topics i mention in my prior post either.
Your unrelated off topic personal comments are out of place on any forum.
Borat: I have allowed the old two stroke engine piston sit in 1/4" of SeaFoam for a day and a half. It appears that the longer it sits, the better the results.
Do you think soaking in soapy water for a couple of days would have done the same? Do you think the lub action could have played a part in the rings like WD-40? SeaFoam seems to be a very thin oil. The SeaFoam rep said the action should be immediate and the product claim is the same.
Borat: Not that the piston is at all cleaned.
From the photo it does not seem to have done anything.
If that piston in the picture soaked for all that time and that is the result I would say SeaFoam was pretty useless. The rep did a similar test and said his piston came to bare metal without scraping just cleaning.
Given what you said you were going to do and anticipating you would get different results than mine I dipped my piston head in SeaFram for a similar time which had already been dipped and repeatedly coated with SeaFram for a day. I rubbed off what I could of the looser carbon first leaving gum imbedded carbon and lots of it but less than your piston. My container did not look close to yours. It was barely discolored being mostly some minute particles of carbon and not many which fell off. The soaking had close to zero effect on the buildup on my piston.
Borat: However, by the looks of the residue in the container, it seems to have had some effect.
Did you rub off the loose and flaky stuff first?
The blown up picture seems to show caked on gummed carbon on the rings. Is that correct?
Again, given the look of the piston I’d say it did not have any useful effect regardless of what was responsible for the rings loosening.
I’ve had the gum bound chips in SeaFoam for three days with no noticeable breakup of any varnish. With swirling the cup nothing in there changes.
We have somewhat similar piston tests but differ widely on the conclusion.
Borat: However, my results seem to indicate that there is some redeeming value to using SeaFoam.
How big is “some”? From what I can see “some” is very small and not worth making a claim for it having “redeeming value”. After seeing what SeaFoam did with your piston I would not make any positive claim but evidently you evaluate that outcome differently.
For me it did not break down gummed carbon in a cup over days.
For you it loosened the rings.
For me it had not effect on the piston.
For your piston it does not seem to have had an effect either.
For you it seemed to make a motor run better although you said you could not directly attribute it to SeaFoam.
For me three similar applications to a 7hp yielded no result. But I checked out the head interior and valve area first, put in a gummed plug and laid out a tarp to catch any purged particles. There was no change in the head/valve area, the plug was the same and no particles found on the tarp.
I come to a much different evaluation of the usefulness of SeaFoam as a gum and varnish remover for the head area or carb, as a motor rejuvenator or as a moisture/water eliminator. It may have some usefulness as a lub.
Although our tests yield basically the same result our evaluation of those results differ markedly.
