Default Sea Foamed it!

Questions of Sea Foam came up on the forum not to long ago. I'd used it in the past with success, but not on the vette. Well after replacing the main fan and installing a lower temp switch-letting the car idle alot testing the above, they all work fine, left for work and noticed a slight miss, no codes. Thought it might have carboned up, got Sea Foam added it and :D running great :D of course it through a code which I suspected was the 02 sensor after disconnecting battery alls well :thumbs: I think this stuff works great.
Next need to replace starter :mad its been acting up. And oh yeah, gave up on the cluster and ordered one from Ucando Services-$195. plus core-can't spend any more time on that issue. :seeya

How much Seafoam did you put in the engine and did you add any to the oil or fuel? Thanks

You might want to consider taking your starter to an alternator repair shop. A local place here repaired my starter- rewound it, and replaced the solinoid, for $80.00. YMMV

I added one third to fuel tank, didn't add any to crank case, although they say to add a third to crank case, took the remaining two thirds and sucked it out of the can through the egr hose (the one that goes from valve cover to manifold) you need someone to help keep the rpms up while doing this. It will likely throw a code, 02 sensor asking whats going on? After all fluid is in (and it will smoke) shut down for 5 minutes, disconnect battery to reset-you may have to reset twice I did, and yes it cleans the passages and alot more. I've been happy everytime I've used it :D and NO-I don't sell it. :thumbs:

Thanks Mark, but NAPA has the rebuilt for $46., and it's raining in Seattle, the garage is full-so I'm off to the Chevron where they will remove and replace. If it weren't an automatic-I'd do it myself. :thumbs:

Glasstastic, Sea Foam is a 100% petroleum multi use product that says it cleans injectors,carburetors,carbon,fuel stabilizer,frees lifters and rings,de-icer anti gel,upper cylinder lube,dries oil and fuel-wow, alot of claims :rolleyes: BUT-I can say this, my first experience was with my boat (inboard motors) when I trolled they would get carboned up-cough and spit an embarassing amout of carbon out the exhaust onto the water-alot, and it made my transon black-someone recommeded Sea Foam-I used it and man was I impressed :eek: no more problems. Since, I've used it in my Jeep, Taurus and now my vette, have been happy with the results :D and believe me I'm not one easy to fool about additives :thumbs: I think you can buy it at most parts stores.

I used it on my Vette @ 75k miles and at first I thought it was ok. Then when I pulled the heads @ 85k miles I see it didn't that good a job for cleaning carbon. My heads had so much carbon build up that the valves were seating on the carbon. If this stuff works so good, wouldn't you think the heads would be cleaner than that?

Hey War Machine, I'm not selling the stuff, just I personally have had good experience with it ;) As far as your heads go-how much carbon built up in 75k before the treatment? how much was removed? and how much more after 10k, alot of carbon build up depends on the type of driving we do. I don't think any treatment is a cure all, just worked good for me. and others I know :thumbs:

:iagree: its a great product not a miracle cure. It wont remove years of build up but it will remove light to moderate buildup and help minimize buildup with regular use. The major cause of OUR carbon build up is most of us are running our engine temps too low with colder t stats and fan switches. The higher engine temps help reduce emiisions with cleaner exhaust and help reduce carbon buildup. FWIW I am guilty also of the cold stat and fan switch.

I guess it might be good for fresh engines if you use it on a regular basis but for the high mile first time user, I'd be a waste of money. I did put some in the tank and when I had the injectors sent out for cleaning the flow wasn't that bad, so it may be decent in the tank.

It's really not necessary on fresh engines because typically there clean, and I'd think thats a waste of money, except in diesels where it's used for anti gel.
It seems when you let the engine suck it through a vacumn line it's most effective-like anyother product i.e. waxing your car, changing oil it's a maintenance thing, but I only do it every once in a great while.They also claim it helps pass emmissions-hey, and some guys swear by dry gas to help pass-others say dry gas effects or can effect seals-Sea Foam is a petroleum product so shouldn't effect seals. :seeya

rick, thanks for the info and your experience with Sea Foam. I will try to find it local and use it in my 69 and 90. I noticed in your original thread about Sea Foam some ref to cluster problem. I have a active thread asking for help with the digital cluster on my 90. Analogs fine but digital numbers become worms after 30 miles or less and sometimes even sitting still. Electronic climate control will move from heat to auto/ac without touching the buttons and spike fan to max. Head unit for heat/ac and some fusible links replaced says mech. Only one response to my thread and I did that without any change. Someone said bad ground. Another said body module. I'am at wits end. Just thought you may have some knowledge of this or know of someone . Sorry for the long thread. Thanks for responding to my questions/problems. :banghead:
