Smoke testing needed

Due to EVAP problems. Not sure about using smog shop. Not interested in the BAR $500 voucher. I know my car and I need a smoke test, not hidden cost(s) for testing and repairs.

There are lots of ways to make a smoke machine for under $20.00. Google "DIY EVAP smoke machine" . Then start looking for one you can build.

Naw, I already tried it. Not working out for me. I found a mechanic with a history on 740's and he does smoke testing, so, while at it, I can get his expertise locking down the lock ring. Ever since I took out the sending unit in 2015, I have nothing but trouble passing EVAP.
