Anyone used seafoam in their engine? I can't figure out where the vacuum line is to suck up the seafoam?? If someone could post a pic that would be even more helpful. Thanks in advance!

You can use the vacuum line off the PCV valve, but use an adaptor to a smaller diameter hose, to control the vacuum better and not suck half a can in, in 5 seconds.

Install the adaptor and smaller hose (Autozone carries them for pennies), blocked off with a golf tee if possible, BEFORE starting the car to prevent setting a code.
