Stop in for a cup of coffee

I got poisoned from exhaust fumes years ago, truck had a shitty exhaust system and to this day, i have a low tolerance for exhaust fumes. First thing i did was put an exhaust port in my shop door and buy a hose.

Turns out the egr was stuck open, and the boss opted for manual choke to keep it running. I Made a block off plate and installed it
When he wasnt around.
