Have any of you guys used Sea Foam cleaner? A buddy at work swears by it. Says it cleans the carbon deposits in your engine better than anything here the link:

I'm thinking about it but wanted some feedback first.

I am going to buy some later this week. all the mechanics I know swear by it. My manager at Advance was on the phone with a rep for over an hour talking to him about it <img src="/forums/images/graemlins/zombie.gif" alt="" />.

BG-44K

I heard the same thing. I tried it in my Miata. All I saw was a ton of smoke while the engine burnt it off. After that I didn't notice any difference. <img src="/forums/images/graemlins/frown.gif" alt="" />

Which one did you try - the Sea Faom (I'm assuming Foam) or the BG44K?

Never heard of the former, but I know the latter works and works well.

I used this stuff



I held the engine at 3K rpm and allowed a little at a time in through a vacuum port on the intake manifold. Another time I tried it I let the engine stall and left it in there over night. May be after 190K miles of abuse the engine was too gooped up for this stuff to work. The car still goes fine but it's octane hungry and pinged like crazy if I ran 87. I just sold it so no worries anymore <img src="/forums/images/graemlins/smile.gif" alt="" />

Techron for carbon and valve deposits. seafoam in the oil for lifter clickers, fuel for injectors and water in the gas. BG44K for injectors in the fuel, or as an injector flush in a machine.

I use seafoam in boat motors a lot, as their fuel systems tend to gunk up worse with longer fuel sit times and lots of water around.

For real bad carbon deposits, I use water down the carb. The old 6 1/2oz coke bottles were about right. Way back when before steam irons, everybody had a sprinkler cap for a coke bottle to sprinkle stuff when you ironed it. We'd use that, and run the engine at around 2500rpms in N, and sprinkle the water down the carb throat (warmed up engine!!). I bet a spray bottle would work better. This works best with no muffler, NO turbo, and no cat in the way, because chunks will fly. The water steam blasts the carbon deposits off the whole combustion chamber and piston top, and the crap mostly blows out the exhaust. Look at an engine with a blown head gasket and note how shiny clean the combustion chamber is. This will restore lower compression by getting the carbon out of the combustion volume and off the piston crown and out of the quench volume. This latter is most important for killing knock.

Have not done the water down the carb trick since high school in 1975. it was the way to go for sure.

On another note. My vibs. and growling noise just may be two rough ujoints. I dropped the driveshaft a few mins ago and it definately has some worn joints. Front yoke splines look new. Output shaft seal is weeeping so Im pricing the stuff at autozone right now.

Now to get the A/c back in gear....

Me to, but only on two strokes.

I did the water trick when I was younger, backed up to the garage, fired it up, added the water and presto a black garage door. <img src="/forums/images/graemlins/scared.gif" alt="" /> Would not come clean, had to paint it. <img src="/forums/images/graemlins/frown.gif" alt="" /> The muffler was a glass pack so it did not slow it down.

Those were the days, youth that is. <img src="/forums/images/graemlins/rolleyes.gif" alt="" />

So be careful where you aim your rig's butt.

I think Eddy said it all. I was looking at the ingredients for 3M fuel injector cleaner. (the kind that is hooked up to your fuel rail by mechanics) and it has water and petroleum distillates. Sea Foam does not have any water in it, so it might not work that well on the carbon deposites.
