If I follow this video will I be doing everything right? I'm planning on doing it tomorrow.

 

lol What video?

Ive seafoamed before, did 1/3 in brake booster line, 1/3 in gas tank, and 1/3 in um......hell I forgot. lol

 

I always did my splitport through the PVC line and a long hose stuck inside the can of seafoam.

The PVC port is high enough on the intake to feed both plenums.

Its 1/3 can btw.

 

1/3 in the intake via the PCV or brake booster, 1/3 in the fuel, and 1/3 in the oil for 50 miles or so then change the oil! because it will be super dirty.

 

I did mine last week, 1/2 in the pcv valve and the rest in the fuel

 

Seafoam has a low flash point of 55 degree's so by 50 miles it will probably be gone, but it is still a good idea to change the oil because of all the crud it cleaned.

 

I have seafoamed my girly's 'stang a couple weeks ago. Went through the brake booster line. The key is to pick a vacuum line that is close enough to the throttle body to guarantee that the seafoam will get into both sides of the motor. On some motors (like my Dodge Durango's 4.7L V8's) the PCV lines go into only one side of the motor. From just a visual inspection and looking at the engine drawings in the service manual, my girly's 3.8L's PCV system does too. So it isn't good choice to use for seafoaming her vintage motor.

I fallowed the instructions on the seafoam web site. Click on the "Cleaning Varnish and Carbon Deposits - Fuel Injected Engines" link.

I don't add it to the gas or to the oil. Especially not the oil. Modern oils, especially synthetics, have some serious detergents in them that clean your motor. Adding seafoam to it won't help much (if at all), and can easily hurt by thinning out the oil.

I also don't stick the vacuum hose into the can to let the vacuum suck the fluid in due to a very real fear of hydolocking the motor. I _slowly_ pour it into the line while keeping the motor at about 2k rpms with a block of wood on the gas pedal (per the instructions on the sea foam website) not allowing it to stall out.

Hope that helps...
