Do I need shop that has Smoke Machine to find exact leak in EVAP system? on 1997 Volvo 850

In some cases of small evaporative leaks the smoke machine is probaly only way to find leak.

Thank you for your reply, I really appreciate you taking the time to respond! The EVAP diagnostic indicates "Large" Leak. Do you still think Smoke Machine? At $110 an hour for local independent Volvo shop I just wanted to make the best choice. My usual mechanic is $65. but it may take him more time etc. Any thoughts?

I personaly think evap leaks are the toughest to diagnose due the differant things that first have to be done to ut the systm in a sealed mode to do smoke test. This procedure varys with each make of car. As far has to whom you should take it too I cannot comment. It a matter of whom do you have trust and cofidence in.
