After reading posts on Seafoam I went out and bought a bottle today. I sucked 1/3 of the can through the PCV Valve. I let it sit for five or so minutes then took it out for a drive. I didn't see any white smoke coming from the exhaust. I didn't see anything coming out of it. Should I have seen something, or did I do something wrong?

 

Wrong hole, I think you just added it to your oil

 

Nope he did it right, I perfer the PCV valve compared to the brake booster.....it's been stated many times before that if you use the brake boost you have a greater chance of hydrolocking because it seems the seafoam goes to the back cylinders compared to all 8 through the PCV valve. Patatoe1, next time let it sit for about 15 mins and then drive to hell out of it, bring a buddy also and have a good laugh cause it will cause a white-out in your neighborhood.

 

Just so I am totally clear I suck it up through the PCV valve right? I don't pour it down the hole when I take the valve out.

 

Sucky sucky yes, pour into valve cover hole no. I used some extra windshield sprayer hose lines that were lying around and pinched it as it was being sucked into the vacuum the PCV so it wouldn't stall on me. Make sure the engine is nice and hot when you do it also....good luck.

 

Im real leary of using that stuff. After hearing the hydrolock stuff and all it just makes me nervous to use it.

 

Ever open up a modern day fuel-injection intake manifold on a used car or truck? I think you'd decide it was worth it. EGR gasses really aren't doing your system any good.

Just keep the engine running and suck it up through a very small vacuum hose if you have to - dipping the hose into and out of the fluid level of whatever product you are using. Easy as pie.

 

ive used seafoam in all my cars and trucks and use it in my boat in the fall for storage..this seafoam is good stuff....alot of garages use it from time to time...

 

Sea Foam is awesome as a knock-er-loose... you're worried about hydrolock? Don't be. I put some into an engine that had been sitting for a year, prior to startup to lube the rings. The car runs great, no smoke...now I just need some tires.

Last night I had my father drive my truck to the store and back, then gave the motor a SeaFoam treatment. Then after I drove it to clear up the smoke, I had him drive it again and he asked me if I did anything in the time between drives, he said the second time it was running better, felt like more power.
I am a new seafoam user for life!!!!!

How often should it be used????

 

I say use it about 2-3 times a year. I'll probably run sea foam through it in the fall just before the snow flies.

 

I've always been told every oil change, that's from the guy at my local Car Quest who's pretty knowledgeable and trustworthy. Myself, I use it every other change.

 

It depends on who clean your engine is running, really. Basically we're cleaning out the throttle body and air plenums here - the injectors come later (use it IN your fuel tank to clean the injectors) in the system.

So we're looking at some blow-back deposits, some PCV deposits (which may be less with a fully synthetic than with a dinosaur oil), and EGR deposits. Two to three times a year sounds right, leaning toward the 'two.' Carburated and worn injected engines may need it a little more often, depending on the build.

"Air Intake Cleaner" sprays may do the trick, too.
