I've heard others talk about it here. I think it would be difficult to gage it's effectiveness unless some obvious sysmptom went away. I have just used water through a vacuum line into the intake to steam clean away carbon. Seems to work and it's a lot cheaper. In the old days, I'd pour the water right down the carburetor and blow a bunch of black smoke for a couple minutes.
I have used Seafoam cleaners for a very long time with wonderful results. "Deep creep" works well for cleaning air intakes and I have also used it for decarbonizing. Water will likely work also - I just get a little paranoid about hydrolock if anything is ingested too much/too quickly.
I havent had any problems using the Seafoam. As a fuel additive I think the Chevron Techron is a better route.
I used the Seafoam as a crankcase additive.....lost a little tick I had in the engine. Guess it worked that out........then again, maybe it was just the oil change.
How is this put into the engine? Do I pull the vacum hose going to the power brake booster and let the vacum suck it out of the can? I am willing to give it a try but have limited tools and mechanical skill.
I use the Seafoam (double) in the 44 gallon tank diesel in the tank before I change the oil and fuel filter. I like the way that it cleans things out. I have had people tell me to put the 1/2 bottle in something and clean out the top side. I'm scared to try that though.
I use seafoam in all my engines 2stroke & 4 stroke. The spray is great for cleaning carbon from intakes & carbs. I put a can in my tank every 10k miles. If you have a mod motor don't use the brake line to suck the seafoam in. It will flood the rear cylinders. Use the pcv line instead. I had a buddy fouled his plugs using the booster line
Yep suck 1/4 to 1/2 bottle into a warm engine through PCV, then turn engine off and wit bout 5 - 7 mins. start engine may be a little difficult at first then give it some gas intel the smoke clears, then drive it around for a little.
**Caution use outside, when I say smoke Im talking thick white cloud** CAUTION
Kinda funny to see neighbors come out of their house looking for a fire, lol
Pull the line off pcv valve, I took a plastic water bottle, and cut it in half poured some seafoam into the bottom half of bottle then with engine warmed and running managed to get hose into plastic bottle and got it to suck it up.
I heard you can you the brake booster vac line also, but sombeody said it does not get to all the cylinders.
