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

yup 24 mmHg Vacuum is pretty powerful stuff.

awesome

that means you dont have any vaccum leaks I guess

awesome

Reminds me of how the first beer can looks after a hot day at work

That’* impressive

looks like the time my K&N cone filter got sucked in to itself after a temp heat shield blocked the airflow...

Did you let it stall your engine out and then let it sit for at least 10 minutes before firing it up? That is generally the recommended practice. If you didn't do that, maybe it didn't clean as well as it could have.

You could just punch a hole in the bottom of the can after you hook it up to the vac. booster hose. In fact, thats a really good idea... I think I'm going to try it on my car :P

If I remember right, the can says to only put 1/3 of it in the intake at a time. So I usually do 1/3 in the vacuum, 1/3 in the oil, and the rest in the gas tank. Haven't done it in a while though.
