I really hope this was a joke, although I cant say much I almost dumped seafoam in my jeep without it running luckily fearofrunner was there to stop me from a total dumb Fuc* mistake.
in the vacuum system, engine oil, or gas tank? oil and gas tank its just fine to pour seafoam or b12 into with the vehicle not running (dont run it for too long with that stuff in the oil, 15 min or less) but in the vacuum system the truck has to be running to suck it in.
haha that "porting" idea is a joke if you read on
there probably are people that dumb though!
