well, it worked!
I used the brake booster line, had a buddy run it at 1500rpm, then SLOWLY poured in 1/3 can. Let it sit for about 10-15 mins, then start it up (in a well ventilated area) and rev it for a little bit. Afterward, take it out for a "spirited" drive (drive it loke you stole it) for about 10 miles or until the smoke clears.
Bring it back, and change the oil. (I used Mobil 1 5w-20)
I took it out for a drive after the whole service was done. It seems powerful according to the mental dyno. The car seems to run smoother, but a few MPG figures will add some evidence.
Overall, i am happy with the results of seafoam.
