Cearification of Sea Foam use

Certification of Sea Foam use

Ok... I have 2 ans of Sea Foarm sitting on my desk, I've read about every damn post here about using sea foam, and I think I have it down for the most part, but I just wanted to confirm with some of you that have done it before, as this will be my first time.

-Suck up about 1/3 to 1/2 of the can through the PCV valve, then dump about another 1/3 in the hole where it came out of until it stalls.
-After stall, lets sit for 15-20 min then rev the life out of it, then drive like I normally do (crazy as sh-t!)
-Pour a can of the stuff in my tank next time I fuel up.
-Pour 1/3 in the crank case? (This is the one I need help on, I don't know THAT much about cars, but if someone could show me where to pour into the crankcase, or where the crankcase is for that matter, I could do this too.)

So if this looks right, I'll try the sea foam tuneup today. Also, do I need a new PCV valve if I do this, or can I just reainstall the old one?

DO NOT add to the hole the pcv valve came out of. That is the crankcase. You will be adding it to the oil if you do. Only add to the crankcase if you are going to change the oil. When you add to the crankcase, let the engine idle for 20 minutes without revving the engine then change the oil. Absolutely do not drive with seafoam in the oil!

You want the seafoam to be sucked into the intake. Remove pcv hose from valve cover and let vacuum from the intake suck it in as fast as possible without stalling the engine. Turn off engine and let set for 30 minutes then drive the s#^! out of it, make sure most of the time you are above 3000 rpm, this opens the intake manifold runners. You will leave a HUGE cloud of smoke so don't do this in traffic, they will be blinded by it.

Thanx for the tips, I will add it to the crankcase the next time I change my oil, I'll drop some in the crankcase then idle for about 20 and change my oil. I appreciate the reply.

i did it yesterday, didn't stall the car, just turned it off, smoke was intense, a bunch of neighbours who had no idea what was going on came out on their porches to give me disapproving stares. my gf and roommate loved it tho.

I am curious what is this for?

It cleans the carbon out of the top of the engine.

Thanks for the answers from K-Zoo. When I was in the navy we did many underway replinishments along side the USS Kalamazoo. They flew a flag with the letter K in the font of the Special K cereal.

Old timers story

Back in the day, we used to do something similar to remove carbon from the upper cylinders and valves. We did it with transmission fluid. About 1/2 quart of transmission fluid sucked or poured slowly into the intake, followed by 8 - 12 ounces of water. Hold it at high idle until the smoke goes away and you would swear you had a new engine. Only caveat was that if you had glass packs or straight pipes, it was best to do this with the car backed up against a wall. The chunks of carbon that came out the back were rather deadly. We demonstrtated this at the tech school i went to by doing it to an engine on a dyno stand, by breaking out the safety glass around the console. Got 10 extra HP on the second dyno run after the treatment though. :Beer

You also are supposed to do it after the car is up to normal running tempature. Otherwise it tends not to clean much if anything out. Also when thru the pcv tube or air intake it also is supposed to clean several things including the cats.

I ALWAYS add about a third to the oil with absolutley zero problems whatsoever.
ALWAYS!

Just a word of caution when 'dumbing' it into the gas or crankcase. If your car has been very poorly maintained, be advised that these types of additives may loosen up large deposits possibly plugging oil passages, etc. If your car is in decent shape, fairly frequent use can prevent this...which to me looks like about 10 rwhp, if not more.

Again, personal experience shows me zero problems.
