93 loyale, got a thing of seafoam on a whim.

 

where do i pour it? how much? thanks.

put a bit into a cup (it says on the bottle how much) then remove the vacuum line from the brake booster. Plug that vacuum line with your finger, get someone to start the car, use the vacuum line to suck all the seafoam up, (have your friend play with the pedal as much as needed to keep it running while you suck it up; it may want to stall) plug the line with your finger again for about ten seconds (or until you start seeing smoke out the exhaust, whichever is first)

 

Let is sit for ten minutes, then fire it up and go for a spirited drive. You could also do this with the exhaust backed up to a hornet-infested barn, or any other area you wish to eliminate an insect presence in (temporarily at least) Be prepared for BILLOWING CLOUDS of smoke; this is the seafoam doing its job. It soaked off all the carbon deposits from anywhere you see manifold vacuum, and now its all burning off.

 

You can also add to the fuel tank as injector cleaner, and add to the oil as crankcase cleaner. It says it all on the bottle.

Read the bottle... It says what to do. 1/3 in the gas, 1/3 in the oil, 1/3 in the intake. Pour seafoam into your intake until the car stalls out. Wait like 5 minutes, then restart. Crazy smoke. Drive it a bit, feel any differance?

I actually did 1/2 & 1/2 .... 50% right into the intake, and 50% into the gas tank ...

 

Here is a video on Google From Seafoam itself. There are TONS of videos on YouTube where a person does their individual car. Just search "Seafoam"
