Hello Guys,
I hear that Seafoam is outstanding for cleaning the inside of your engine and/or crankcase. Has anyone ever used it and what is your opinion? Thanks Guys.

 

I haven't used it. I was going to; even purchased the stuff; but then decided it wasn't worth it. There's a lot of bad things said about it too and I decided it wasn't in my truck's best interest.

 

What bad things have you heard?

Ive used it. Good stuff, but I use it only for combustion chamber/valve cleaning. I havnt used it in the oil or fuel.

 

I've used it to clean out the CCs on my Mustang, and it works pretty damn good. Suck it up through a vacuum line and if there's anything in there it will knock it out. You will know by how much smoke it produces when you do it. Or you can use water. Suck up a little at a time, and it "steam cleans" the inside of you CCs.

 

Water. lol. That brings back memories! That's how we cleaned up the pistons and the cc's before pulling heads in the old days.


I was skeptical of SeaFoam until I used it. Now I swear by it. I've never added it to the oil, but I've added it to the gas and through the power brakes vacuum hose, and have had nothing but great results (and quite a bit of smoke. lol)! I very highly recommend it!

 

I've added it to all three, with great results. I didn't really see any change in the oil though, but I only ran that for a few miles. I'd do it. I've done it on several cars, one with 180K and another with 220K.

 

Thanks for all the replies Guys. I tried it yesterday and WOW! That stuff works really well. I used the whole can in the intake and half of another in the crankcase. It boosted my oil pressure 5 psi. I will continue to use this stuff. I love the smoke show too. Thanks again guys.

 

That's good to hear, and yes the smoke show is quite impressive.

 

Before starting to use seafoam, I have always given my cars/trucks a yearly does of distilled water. Typically I fed an entire gallon into the motor, ran it out good and hard, then gave it an oil change.

 

What does seafoam do? What do I do with it?

 

Do a search for Seafoam.

 

Seafoam can be used to clean your fuel system, intake/exhaust valves and combustion chambers, and your oil system. Their are directions on the bottle as to what you do and the amounts you use. Basically you can suck it up through the vacuum lines to clean the intake/exhaust valves and CCs, pour it in your gas tank to clean the fuel system, and/or pour it in your oil to clean it up.

 

I'm still really sceptical of using that stuff.. it just doesn't sound good!

 

Damn! That's crazy! You're lucky you didn't hydrolock an engine! I never used more than a cup of water, and just sprinkled it in off my fingertips over the carb.



I don't blame you one bit, I was the same way. The only way you'll ever change your opinion is if you break down and try it.

 

Well hell, it isnt like I dumped the entire thing in once

I fed it in using a small water bottle, but definately more than just a sprinkle!
