Alright, I talked to a co-worker who is a good mechanic. He said if I do the Seafoam into the vacuum lines and in the crankcase that I should be prepared to drop the oil pan and clean any filter screen and the oil pump if I had a lot of sludge in my engine. He also said the oxygen sensors might need to be replaced. He did say it cleaned really well, but you just need to deal with the junk that comes out and the affect on other parts. He said to just pour it in the gas tank and let it work slow. Any feedback on this anyone? Let's hear comments regarding this. Thanks.
I am strongly in favour of using Seafoam and have done so for several years now with great results. However, I fouled the heck out of some fairly new Motorcraft Double Plats last summer when I ran it through my PCV system. Trashing your plugs is a very real possibility when you run it through a vacuum line. Keep that in mind.
I now run Seafoam through my gas fairly regularly now. Preventative maintenance is how I see it. I also plan to put some in the oil just before I change it. Unlikely I'll run it through a vacuum line again. Firstly, the Brake Booster method is the easiest way to do it with my 5.0 but you don't get full coverage. Secondly, since I had a 1" UI spacer installed, it's a nightmare to get at my PCV now and even when I reach it, it's a ***** to get the PCV out of the line (I have a brand new PCV setup). Thirdly, I don't want to trash another new set of plugs.
Seafoam does work as advertised. I've seen a lot of irrational reasons in this thread for not using it. It's good stuff. I don't blame fouling spark plugs on the Seafoam. I blame it on me for letting my system get so gummed up that that the plugs got fouled. The Seafoam didn't mess the plugs. The crap that was released did. Seafoam does not trash sensors, gaskets or anything similar. If you use it in your oil, just drop your oil. The bulk of the sludge will drain with the oil. If you're really worried, fill it back up with cheap oil and do another treatment in a thousand miles.
As mentioned in my first post in this thread, if you're worried about the induction method, run it through the gas. The smoke show is fun to do and worth trying at least once. You'll notice the difference right after if you do it right. Do check your plugs after doing it this way. Plug fouling is is not a common by-product of doing the "gas method" from what I've seen.
There are MANY Seafoam posts in the archives. Have you put your SEARCH buttons to work to see? Read up and you won't be afraid to try it. Seafoam is well known not just on this site, but other automotive sites. I used it on my wife's Subaru and even my Lawn Boy.
