#139322 It's not for "locked up" motors.

Put 1/3rd of the bottle in a shallow cup of some sort and suck it up into the intake manifold at the brake booster hose (separated from the check valve). Suck it up slow. Too fast and the motor will stall out. Keep your thumb part way over the hose to keep the idle from going too high.

Pour 1/3rd into your crank case at the oil filler cap. Drive it a couple miles.

Change the oil while it's still nice and hot. When the engine cools down, change the spark plugs. They can get pretty fouled up especially if your engine really needed the seafoam. You'll know your engine really needed it if it blows a ton of smoke out during step one.

Probably a couple hundred posts on this topic.

#139323 The only way to get the intake manifold and throttle body clean (they get quite dirty in a short amount of time) is to pull them off and run them through the parts cleaner at a head shop. Make sure to take the MAP off the throttle body first and to get new gaskets. Use a die grinder with a fine sanding wheel to get the intake manifold gasket off the head and the intake manifold.
