I’ve seen countless “miracle stories” related to using seafoam in a high mileage engine, and some warnings on losing compression due to removed carbon that was holding the seals.
I wanted to start a thread for people who are considering seafoaming their engine, me being one of them. (KA24DE with 205k)
How many of you have performed this procedure on a high mileage KA or any other engine as a matter of fact?
How was your experience? Would you recommend it?
Before and after stories?
I hope this thread helps other people in the same boat as I am in.
Thanks for your responses; discussing first hand experience is very helpful to the community.
Dont believe the hype. The amount of carbon it will remove isnt worth your while.
Besides it can actually have reverse effects. If you have carbon buildup that has been acting as a sealer say on your valves then removing it will be detrimental.
Furthermore, what type of gains do you expect to see? Sure it may get rid of some carbon but really is it going to do anything for you? doubtful. From what Ive read its meant for really old engines.
there is a thread here about. http://forums.nicoclub.com/zerothread?id=126583. kouki has a point though, removing carbon build up can cause your valves not to seat properly causing poor performance.
i seafoamed my KA and honestly i dont think i real saw or felt a difference. i did mine at 200k. the only thing i think i could notice was a bit smoother idle.
i also seafoamed my old civic a couple years back with around 200k on it and again i didnt realy notice a difference.
on both cars i used it all three ways… through the vacum line, the crankcase, and in the fuel.
I used it on my Trans Am, and it didn’t make a massive difference. My gas mileage went up a little though.
There is apparently better stuff out there on the market, but there is nothing
wrong with this stuff, I’d recommend it.
I’ve heard of people saying stuff about their head gaskets going after using it, or valves getting all messed up. I’ve never seen anyone post saying it happened to them, only “they heard it could happen” and if either one of those things happen, chances are something was going to go wrong with it shortly anyways.
