Seafoam is teh *****!

I have used this stuff for a couple years now. The first time was on a toyota pick up with 210,000 mi.

Not only was there mad smoke - but small chunks of crud on the concrete under the tail pipe - it points down

It works better if you have a friend:
Driver can rev engine ( 2 grand worked) while you pour into the opening of a vacuum line - I used the brake booster as it is larger in diameter
When you pour, just let the vacuum suck it down

I also added a can to the gas tank

Wait a week, change oil. Good to go.

This is from before I had the PI headswap so my engine should look similar to yours. See the piping that I circled pull that off while your car is running. If the car dies then that is the right line to put it on. If the car doenst die then come on here and post again and I will take a different picture and circle the other line it should be.

I just ran some in the car. If you look in the picture with the red circle, I took that hose off, and poured the seafoam into the hose itself, with the car off. I also put some into the plennum itself, but not much because it started to get messy. Then I cranked it up for a sec to get it going through, then killed it, about 10 mins later, I cranked it up and got the smoke show. Is this way of getting it into the engine OK too?

After hearing all the fuss and reading through this 90 page thread, I decided to try this stuff out. My car has 75,000 miles on it and I just took off the rubber gasket with the two red lines coming out of it and used a straw to suck it up through there. Good Lord was there a ton of smoke, I can't imagine what the people behind me thought when I pulled onto the main road. Hey for $5 a can, this stuff is hard to beat.

When you add seafoam to the crankcase are you supposed to change your oil after a certain period of time, or are you supposed to just leave it in there until the next regular oil change?
After I add SeaFoam to the engine oil I wait 100 miles approx for it to work and then do a oil change.

Yea -- you drink enough of it, it will cure ALL your ills :eek:

Yeah. I just tried it on a 1978 Englishman. Had my wife put her finger over one nostril and cover my mouth while I sucked up half the bottle. Is that where I was meant to put it? can someone post a picture? Will it cause damage to my internals?

A few chunks of sh%^ came out the rear. I'm going to burn through a hundred pints and then change my pants.
 
+1 on that picture to:nice: i seperated that rubber angle hose from the plastic one to the pcv and poured into that which fed right into the upper plenum. I let it sit for five minutes than cranked r up to watch the show. My neighbor came outside to see what the hell was going on, i just smiled and waved to them:D Then i took her around the block and eventually stop puffing. To be honest with u guys i didnt notice much of a difference after ward, which was surprising considering she had a heathy 100000+ highway, low rpm miles on her from the last owner.
