[V8] Seafoam

[Buchholz, Steven]

... I followed the directions on the can.  In my case I did not pour it into the tank, but sucked it in via the intake.  I pulled off one of the vacuum lines for the vapor canister to introduce the Seafoam to the engine.  As I recall I warmed the engine a bit, and then sucked the better part of a bottle into the engine.  The goal is to suck enough in to stall the engine ... I found this a bit difficult to do.  I then left the engine sit for a few hours ... and fired it up.  Good grief, the motor smoked for quite some time, but once the stuff worked out I haven't had any oil smoking problem since ...
