Got an 88 mustang 5.0 lx that I want to seafoam. I was told half in the fuel tank and half in the brake booster vacuum line? Which one is the brake booster vacuum line? Is it on the vacuum tree? Diagram anyone lol?
Thats honestly what I figured. Is the portions right though? Half in the b/b line and half in the tank? I just did an oil change so Im not going to run any through the oil. Do I need to have someone rev the engine lightly as im pouring some in the vacuum line?
Yes 50% in the tank and 50% through the injectors or vacuum line.
The instruction say to make sure the car is warm and pour very slow into the vacuum line.
This is the best I can do with what it says on the Sea Foam can.
Ah the seafoam, required ever 10k miles on a B headed car. Never was a huge fan of basically lighting the inside of your crankcase on fire (which is what it pretty much does) but I've seen too many ****tily running cars fixed by it. Also have seen more than one dip**** ruin an engine with it but that was their own damn fault.
I take the hose off that says S on it from the vacuum tree that runs always to the front of the throttle body. Hold it at 3500 rpm and pour it in there. It's the same as it idling and dripping. I do this at my shop all day with a mini tank you pour the sea foam in with a hose you put on the throttle body and let it rip. Just don't let the car die cause it will be hard to start.

By the way my boss puts about 80 psi thru the throttle body of seafoam. Cleans the intake and some of the combustion chambers
