What happens to the catalytic converter when it gets hit with all the gunk that Seafoam cleaned out? Maybe it won't poison the converter, but maybe it will. Smoke is particles that are too large for light to go through and thick smoke means you are more likely to clog a converter than clean it.

Haha yeah. Mine was straight piped when I did it, so I dont know.

Yeah...or maybe don't put it into the crankcase. Just sayin' as I had a catastrophic (main bearing/threw rod) once after using "Motor Flush" in a V8.

I change the oil immediately after the smoke-show of SeaFoaming the top end.

Oh. I didnt have problems like that. But I did the seafoam right before I was ready to change my oil.
