Advanced method for finding vaccum leaks

[ontherearwheel]

I had a to work on a 03 2500 HD couple weeks ago. It was showing three codes.

One was related to a MAF error and the other two were bank 1-2 lean condition.

Did the usually YouTube research and came across a way to check for vacuum leaks I really liked. I never was a fan of spray carb cleaner or WD 40 around to find a vacuum leak.

Water bottle with a small hole punched in the top. Sprayed along the intake and head........could hear the water being sucked in plus there was steam coming out the exhaust. No mess, better control in spraying.

Just a little tip.......

Ever Google a problem with a vehicle......only to find out......it's a common problem........like exhaust manifold bolts breaking from just normal use as what also happen on this truck......thankfully there was a manifold clamp to fix it.

In addition, the instrument cluster had to be rebuilt......nothing work......a common problem.....

Just venting a little I guess.....

I was taught to use water in a spray bottle back in the 60's.
Spraying solvents on a hot engine/pipes throws too many red flags.


My dad showed me how to douse a Lucky Strike in a coffee can full of gas though.

Maybe our fathers knew each other. Mine was fond of taking a last drag and flicking the butt of his Raliegh into the pan of gas he was using to clean car parts with.

He was a bit of a pyromaniac. When I was kindergarten age, he used to have a Cushman scooter that didn't like to start. He claimed it had a cracked head. To get it running he'd lift the seat, pull the plug, and pour a little chloroform in the cylinder and quickly reinstall the plug. Then he'd pour a bit more chloroform in the carb and give it a swift kick. BOOM!!....it never failed to start with the chloroform encouragement. It didn't dawn on me until years later why the head was cracked.
