I did a Sea Foam treatment on my 95 today. This was a first for me. I had no idea that brake booster/vacuum line has that much suction.
To my suprise it didn't smoke that much out the tailpipe. Seems like everyone says when you do this you will get a lot of smoke the exhuast.
I had a little but nothing like what I get out of my boat when I fog the engine for the winter.
The hose fit the can perfect and I was thinking cool no funnel needed....guess what happened
See picture below.
I did not squeeze the can any it collasped in my hand
