Sea Foam Review

Valves???

Sea Foam will not fix a badly needed valve job ;)


Not sure there are any liquids that will add metal to valves, that was not a required repair. Setting the vacuum showed no indication of bad valves, sticking valves, worn guides, weak springs, bad rings, poor timing, carb settings, leaky intake gasket, plugged mufflers, or leaky head gasket.

The rebuild to this carb was lame, accelerator pump was not hooked up and the metering needle carrier was in backward. Engine ran but as you can imagine it fell on it's face when you tried to accelerate. The past owner just nursed it to shows and polished it, I almost think it is (was) the same oil that was in it when he bought it. Rebuild was done 10 years ago and my hope was that the Sea Foam would remove any buildups that were keeping it from running more smoothly after the above was fixed. Didn't happen, got very little smoke when I ran it through and even after the soak it put out nothing. That's why I mentioned the leakage of some gas in the throttle rod pivot. Address one problem at a time until the issue is gone.

On the other hand the issues in the carb may have come from someone trying to fix an ignition problem by working on the carb, that was screwed up also and was dealt with first. You can never tell how many monkeys have been at the zoo before you got there.

The engine was a complete tear down, clean, and rebuild at the same time the carburetor was done, (hopefully not the same guy [monkey]). Runs great, no smoke, choke, puke, or death rattle.

Looks like a slight rebuild on the carb did the trick. Glad you figured it out. I actually thought of a sticking valve or valve job running rough. A great product just the same regarding Sea Foam. Sea Foam used in the crank case also promotes clean valve stems, better piston ring to cylinder wall retention as it cleans the rings and removes moisture the oil. On my C5 the moisture problem at start up below a temperature of 140 degrees, the condensing of water in the PCV tube before the valve and oil that mixes with it from the crank case. This creates a brown sludge that is drawn into the intake manifold at idle where vacuum is at it highest. This resulted in a baked on sludge in the intake ports, combustion chambers on top of the valves. The need for the oil catch can has resulted in a 95% reduction of oil in the intake manifold. Oil vapor and some moisture still gets in, but Sea Foam has kept the intake clean for me. I found out how bad this problem was during a head swap.
 
I assume that adding Seafoam to the crankcase would mean putting it right into the oil?

It sounds to me like there really is no wrong place you could put Seafoam :L
 
I gave my Vette the Seafoam treatment and got nothing. No smoke? It runs great perhaps the previous owner seafoamed it? But my belt is squeaking like crazy (not related to the seafoam obviously). I'm assuming my belt is glazed.

How Many Mechanics Use SEA FOAM In Tune-Up of 4 Cycle Gasoline Carbureted or Fuel Injected Engines
Autos, Trucks, and Tractors
  1. <LI class=plain>With engine warm, slowly pour 1/3 to 1/2 pint through carburetor or throttle body throat. (If vehicle is port injected slowly pour SEA FOAM through direct manifold vacuum line that will feed all cylinders, possible sources are P.C.V. valve or brake booster line.) This will pull SEA FOAM down on top of the pistons and to the back of the intake valves to dissolve carbon. Turn ignition off. Restart engine after 5 minutes. If severe carbon build up is apparent, use more Sea Foam as previously directed. Make sure exhaust is well ventilated when using Sea Foam in these various ways as fumes will be extreme for a short time. <LI class=plain>Pour 1/3 to 1/2 pint into oil crank case to clean rings, lifters, dirty parts and remove moisture. <LI class=plain>Pour 1/3 to 1 full pint into fuel tank to clean injectors, carburetor jets, fuel lines and remove moisture.
  2. Immediate Results: Smoother idle, increased R.P.M.'s better throttle response and improved performance. See label on can for detailed results for use in each area.
FUEL TANK, CARBURETOR, INJECTION and OIL CRANKCASE.
For Peak Performance, Use SEA FOAM Every 2,000 to 5,000 Miles
  • A 100% pure petroleum product for use in all gasoline and diesel type engines, both 2 and 4 cycle. OXYGEN SENSOR SAFE.
  • Cleans dirty engine parts internally by removing harmful gums, varnish and carbon. WORKS AND PERFORMS INSTANTLY.
  • Removes moisture from oil crankcases and fuel tanks.
  • Stabilizes and conditions fuels. Use for engine storage.
  • Cure hesitations, stalls, pings and rough idle due to carbon buildup.
  • Helps pass emissions test. EPA Registered.
When Used Thru Injection or Carburetor
  • Cleans carbon build up
  • Cleans intake valves and pistons
  • Gives smoother idle
  • Cleans catalytic converter odors
  • Cures hesitations and pings
  • Restores power and pickup
  • With warm engine running, SLOWLY poor 1/2 pint through carburator, throttle body or direct manifold vacuum line that will feed ALL CYLINDERS. Possible sources are P.C.V. valve or brake booster line. Turn ignition off. Restart engine after 5 minutes. Be sure exhaust is well ventilated. Fumes will be extreme for a short period of time.
  • For use in injector cleaning machines, use 50% SEA FOAM and 50% fuel.
  • Fill diesel filters with SEA FOAM to clean injectors fast.
When Added to Crankcase (Oil)

  1. Frees sticky lifters and rings
  2. Increases R.P.M.'s vacuum and compression
  3. Cleans dirty parts
  4. Removes moisture
  5. Cleans PCV valve systems
One pint treats 10 quarts of oil (avg. 1 1/2 ounce per quart).

When Added to Fuel Tank
  • Cleans fuel injectors and carburetor jets
  • Cleans carbon as you drive
  • Lubricates upper cylinders
  • De-ices and removes moisture
  • Diesel full conditioner and anti gel
  • Stabilizes fuel
One pint treats 8-25 gallons of fuel (average 1 ounce per gallon).

In Injector Cleaning Machines

Add a 50/50 blend of fuel and SEA FOAM into injector cleaning machine. Run directly through the fuel rails to clean injectors fast. Add SEA FOAM to your fuel tank to clean injectors as you drive.

My 99' coupe didn't smoke much either must have a better PCV system than my 2003. ;shrug
 
Now you tell me.....

OK, here's what I did wrong, was unable to "poor" slowly as instructed. :chuckle
 
I ran the SF through my engine but i didnt get any smoke, maybe i didnt put enough in, im not sure.

I dont think i noticed a difference at all, but i know that any unseen enemies have been destroyed and thats what counts :D
 
The squeaky belt issue seems to be confined to those dewy mornings, so im assuming its condensation of some kind. It happens less often now, so its not really something that occupies my attention. I suppose i can leave it be, i havent noticed signs of imminent belt disintegration so i think it should be ok. Thanks for asking :)
 
With all the talk about Sea-Foam in the Vettes, I was wondering if it would work on my daily driver 95 (censored) Crown Vic. Read thru the posts and it seems to me that there is nothing that can't use it. I'm gonna hafta get a can of it and try it in the (censored). 156K will make ANYTHING run sluggish! Don't know when I'll try it, but I'll definitely post the results when I do. Thanks to everyone who contributed to this thread.......it made for some great reading. Todd....you got me SERIOUSLY thinking about a catch can for "JetBlu"!

Cool, I like to try different products and the Sea Foam, I just can't say enough about. The catch cans really work well and are the answer to the oil in the intake problem. Both working together, your car will run real nice. Sometimes you don't realize how just ok it was running until it runs real well. There is that much of an improvement. If you have aftermarket exhaust you will know. The stock exhausts are so quiet it is harder to tell.
 
Well.....I did the Sea Foam trick with the Crown Vic Monday night. Put about half a bottle thru the intake, shut it down, waited about 20 minutes, then started it back up. Tuesday morning I was able to see the car again! D-A-M-N...did that thing smoke! The "check engine" light was on before I used the Sea Foam, and it was still on after the car quit smoking. Drove it around on Tuesday and the "check engine" light went out! All I can say is that the engine doesn't surge anymore at idle, doesn't make as much noise, is MUCH smoother when accelerating, and the car even shifts better.
GOOD STUFF! I'M SOLD!
Andy
 
Got two cans of the stuff rolling around in the center back storage compartment, just waiting to change the oil afterwards. Now about the guy with the belt chirp on the humid mornings, best fix I've found is the Goodyear Gatorback belts.

Haha, the same thing happened to me yesterday helping my buddy with his daughter's car. 1997 Ford Taurus, 143,000 miles with a check engine light and rejection sticker for failed emissions. We gave it the Sea Foam treatment and took it to Autozone to scan for the codes. The light went out before we could scan it, so we hurried it to the inspection station and it passed lol! We stopped back up at autozone and ran the codes. It needed a O2 sensor and an IAT sensor, but kept the light off long enough to pass the inspection. This definitely surprized me.
 
Do you really have to change the oil after the treatment?

I figured you dont need to if the stuff is already getting burned anyways? :confused
 
I'm curious...
Todd, are you a Sea Foam distributor or retailer?
Nope, just a user. I just happened to stumble on the product after doing a head swap and saw how bad the intake, exhaust ports and combustion chambers looked on my stock 243 heads from the oil being drawn in through the PCV valve into the intake. The oil catch can along with a treatment of Sea Foam every two oil changes has done wonders keeping everything clean. Another use I found for Sea Foam was if you are showing your classic C3 Vette, use some Sea Foam to clean inside the exhaust tips. I was at a show last Sunday and the judges were checking inside the tips. It removes all the hard to remove carbon inside.
