I've used seafoam in the tank but I read for the best cleaning you are supposed to use half of the can into the intake thru a vacuum line. Can anyone give me the step by step on the proper way to do this? Should the car be running first when the vacuum line is disconnected? do you just stick it into the can and let it suck up half the content all at once or a little at a time? What works best?

Thanx.

Disconnect the brake booster hose first, then with the engine running hold the brake booster hose just inside the Seafoam can because the suction from the brake booster hose will be a lot and you want to regulate how much will be sucked into the engine.

You'll see what I mean when you do it. Also, don't let the engine stall because the cylinders can become hydrolocked.

Let the engine suck in at least 1/3 to 1/2 the bottle.

I pull the vacuam hose off the brake booster and put a small funnel into the hose, this way you can regulate how much enters the intake. Start pouring Seafoam into the hose until the engine just starts to stall, then back off until it recovers and then pour it in again. Do this until you have about a third left, then pour it in faster until the motor stalls or is close to stalling, then shut the motor off and let it sit for 10 minites. After 10 minites start the engine and let it idle until it stops smoking, this could be 2 minites, or it could be 5 minites, it depends how dirty your motor was.By letting it sit for 10 minites after shutting it off you are letting the Seafoam eat away at all the funk in your valves and pistons and it really cleans it off..Ive used Seafoam in my Outboard motors and cars for years and theres nothing better for cleaning the rings and pistons.By the way, this is how the Seafoam salesman told me to do it many years ago. It will not hydrolock your motor because your shutting the motor off as it stalls,just don't keep pouring after the engine stalls or is shut off. ...WW

and there are actually a few videos on youtube that will give you an idea of what to expect (helped me). I have to say that I was impressed after using seafoam.

I myself have had great results using it on many cars and trucks.
