The other night I got a wild hair and did the “Sea Foam” thing for my 3FE. I looked at the Haynes manual and I thought that put the Sea Foam in the right PCV hose. Nope- I sucked it through the hose in just behind the oil cap. Don’t know what that hose is called. Went up and in just like the threads said. I realized that I put it up the wrong one after looking the diagrams on the SOR website. I got a little white smoke and that was about it. Runs a little better. Going to change the oil in the next day or so. Should I do it again? Could I have screwed up anything? Mass air flow computer?
