Checking my vacuum

[Volky_one]

After cleaning my PCV system I started having a rough iddle and had no time to fix, today I had some time to check the vacuum using a home made tool that I made out of a soup can. the can is a little smaller in diameter when inserted in an intake tube, but it goes all the way to the tube's elbow and fit. I have an 80Gal compressor, lowered pressure to the lowest end possible ande fitted the can to intake, to my amazement I found a leak to one of the fuel injector nozzles, maybe more were leaking. attached are some pics of the tool.

Very interesting! Did you just blow the air and then listen for air seeping out of the hoses?

With regulated pressure lowered close to zero, there is no air noise heard in the hose,and with the cup tightly attached to intake tube, the air exit only where it escape thus finding the leak.
