Seafoam Anyone ?

[jeeperjohn]

I have used seafoam in the intake prior to smog checks for years with good results. I recommend Marvel Mystery Oil as an oil additive.

Seafoam took away my IMRC stuck open condition on my 07 F150. I kept getting the code and clearing it, then after using it in the brake booster line, it hasnt came back 12K later.

Just used seafoam 1/2 can thru brake booster hose. Got almost no smoke but the expy downshifts less and pulls better on hills and passing.

I did it a few days ago. Very little smoke and my truck is running smoother so far. She was idling rough and running rich. After clearing the code and 34 miles later she is ok. Only time will tell.

Am running a bottle in the tank right now. I used a fuel system cleaner first, with excellent results. It made so much of a difference I decided to do a can of Seafoam two tanks later. I am not seeing the same level of improvement but improvement nonetheless.

I don't think seafoam (via the gas tank) can hurt anything. I am not brave enough nor require it fed directly into the engine via an intake hose somewhere... yet. But when I do, Seafoam it will be!

I searched and searched the forum looking for an answer to my question before posting this, so don't hate me too much for beating this dead horse but how much seafoam do I "slowly add" to the brake booster line?

I bought a 16 oz can and put 8oz in the gas (we were just under 1/4 tank) so I have 8 oz left. I am replacing the spark plugs this weekend and will be doing the seafoam as part of the process. None of the video's, comments or anything said how much to add.

Can I just slowly pour the remaining 8 oz into the vacuum tube or do I need more or less? Any input is appreciated. Thanks

you can do that amount...I used 1/3 of the can when I did it to my truck

 

[Boose]

When I did my plugs, I did 1/2 can twice through the brake booster, and a full can in the tank. After the first half, I took it out & drover it like I stole it. Then, the night before I did the plugs, I did the remaining half in the booster line. At the end of the pour I allowed it to stall out. Doing it this way left things a little wet with the seafoam. I attribute this to why none of plugs broke . That and I used an impact gun.

Good luck with the plugs Bigbri! Lots of videos out on how to make the process a little better. Let us know how it goes!

 

[bigbri7870]

I didn't get to them yet....Hopefully this weekend. I want to get it done with, the suspense is KILLING me!! 102K on the original plugs....

yeah its time to change them per 100K maintenance...I changed mine at 94K or 97K and one still broke

I tried Sea Foam in my '11 Expy but really didn't see any marked improvement.

I've honestly used it on more cars than I can remember and only once had that o2 sensor problem. I got a little over zealous pouring it in my old Hyundai... My instructor in trade school (1999) was a GM master tech and they swore by "GM top engine cleaner" which he claims was made by the seafoam people and they actually added it right through the brake booster vacuum. At the time it was almost impossible to find. Napa was one of the only places that carried it but its really caught on cause it honestly does work. You should see the cloud of burnt carbon that comes out of some vechicles.
When I worked for Honda we used wellfleet or well something I can't recall exactly what it was called but it's almost the same stuff we just used one of those drip devices. We got 79.99 for the job if the service advisor was able to sell it when we recommended it. Talk about gravy money.

Its not burnt carbon youre seeing. Itss then oil in the seafoam. Gives a dramatic effect people need to see.

The GM stuff is strong. As I posted earlier, I used it on my 82 Mustang 5.0, that had a bad detonation problem. After using a can poured slowly through carburetor, pinging all but went away. It was a strong smell while pouring it, but it worked. Probably burning off a lot of built up carbon. I changed the oil right after.

Let the range tick down to ~130 mi, pour half can into the tank (use a narrow funnel for capless 3rd gens), half can into the crankcase.

Drive ~100 miles, let it cool a bit so you don't get burns, then change the oil

Highly effective

This stuff is made for two-strokes. That's why it has been around so long. It's not going to do anything in a four-stroke and it adds alcohol to the fuel so if the vehicle sits for a while it'll absorb water.

Seafoam removes water in the fuel and cleans injectors and the fuel system as it runs through. Been using it in all my small engine and motorcycle fuels for a decade plus. Never have had to remove a carburetor and go through it since. Moisture in fuel destroys carburetors and anytime you buy regular gas you are getting an ethanol mix which draws water but Seafoam counteracts that and removes the water. I use it in my vehicles about every three months. Word of caution. Do not overdose, use as directed. PS I only buy 100% pure gasoline, known as recreational fuel in my part of the country, for my small engines and motorcycles.

LOL I think I'll give it a try in my 1929 Model A Roadster pickup. Let's see if I can boost that 40 HP engine a little!
