Yesterday, for the 1st time in the 5yrs I've owned my Cherokee, my check engine light came on.
It appears there's an EVAP issue. I have to track down the leak, & I need a smoke machine, but they cost $1000. :D
I've seen homemade smoke testers made out of paint cans & metal bottles/cylinders, & I've seen fog machines used too.
I found one particular idea that looks pretty good, mostly because I have access to all of the parts for $0.00 8)
Here's a rough idea of what I want to do... using a metal cylinder, old glow plug & a cheapo 12v air compressor...
I found 3 good GM 6.2 diesel glow plugs, & a friend gave me a couple VW ones.
My friend says the GM 6.2 diesel glow plugs should not be run at a full 12v or they will fry.
I'd need a ballast resistor or a LM7805 voltage regulator to step the voltage down to 5 - 7 volts.
He says the old VW ones he gave me will run full 12v & last a long time.
What do you guys think? Anyone ever made one of these before ???
