Hi guys!

A few months back while doing a routine check with the truck on idle I heard a noise, like a vacuum leak noise. Today I checked again and definetly the vacuum noise is louder. I can't tell where is the noise coming from. Any suggestions or ideas?

Used to be, one would seek out vacuum leaks via short bursts of ether (starting fludi) under the hood. When you hear the engine change, you found the leak.

Not sure if this is still standard practice.

ymmv
