very nice detailed instruction..
i would like to add 1 very important safety issue.
on my old 1991 toyota celica i had a small exhaust leak where the gasket goes connecting the pipe to the manifold..

DO NOT SEAFOAM WITH AN EXHAUST LEAK THAT CLOSE TO THE ENGINE BAY!!!

my engine had caught on fire

 

I did a seafoam on my 2000 Monte carlo SS and at 208 000 Km i had a small amount of smoke..... less than i expected.... but it feels more responsive

 

i wish i knew where everything was to put the seafoam in on my ls

 

I use seafoam in all my car's....When I store the Chevelle I fill the gas tank and put in a can of seafoam. I Drive it about 10 miles then when I get home. Put the battery tender on it. Cover her for her winter nap. And forget about her till spring. Then I take out the plugs. Squirt oil into each plug and replace the spark plugs. And FIRE AWAY.... Starts every time no problem. Only thing to do is check the tire pressure. Seafoam is some great stuff...

 

I am going to give this a try before my next oil change.... Thanks for sharing your find Justin!

 

Agreed! Can someone that used seafoam post a diagram or pics???? Please?

for a V6 and V8??

 

i'm gonna be running this through my monte today, i have some running through the tank aswell

 

Thanks.

I echo the previous request. Can someone post a pic of where the vacuum line located on 3400 engine?

 

The line that comes out behind the "4" in "3400" is the end of the brake booster that goes into the manifold. Follow it to the brake fluid reservoir, pop it off and voilą.

I just picked up a couple of cans tonight, I'm going to give it a shot tomorrow morning.

 

Did my Saturn last Friday, that thing was bad... Smoked for half my drive home after work, and that was already letting it run for 20 and taking it for a spirited drive on my lunch
