I took the PCV off of the valve cover and slowly sipped seafoam up into the intake today. I assumed it would feed all cylinders and such, since the line goes straight up to the top of the intake manifold. But I got no smoke at all, so it has me wondering if I did something wrong. Some say use the brake booster vacuum line, but others say the PCV line does the same thing.

Anyone know for sure whether or not that PCV vacuum line feeds everything I'd want it to for seafoam purposes?

Should I put some through the brake booster line as well, or does that line feed to all the same places as the PCV line?

If anyone has some info on this please let me know!!!

Thank you

cliffyk in the main forum informed me that 4.6L's don't have a brake booster vacuum line. If that's the case, what other vacuum lines are available on the 4.6L DOHC? I haven't had this Mach for very long, I don't know the engine that well at all

Any knowledge to share? Thanks!!

Couple of friends told me not to sea-foam the mach 1's motor. I forgot why though?

I was wondering the same thing.

I too has used seafoam in the past with great results. Why is it not a good idea with the DOHC?

Some thing about small line for the oil to move from the bottym of the motor to the. Alve train. Carbon deposits breaking lose and plugging the oil line? Doesn't sound right. So I went ahead and tried it on mine through the PVC line on the drivers side to the throttle body. The Mach refused to die! So I didn't bother on letting it soak. Didn't. Price any changes after words.
