Hello All,
I just did the leak down test on my injectors for my 263k miles 2002 170" ex fedex truck. The number one was replaced last month but I started to see Black smoke when I step on it so I did this test. The number 2, 4, and 5 are all over or getting near 1/2. The number 3 isnt even registering (barely) anything(what could that mean). Thanks for the write up on how to do the test it was easy.
The turbo has a little play on the turbine bearing and the vein celenoid makes a buzzing sound under vacuum, Could that be the culprit for the black smoke under load?
(Giving her lots of gas to get up to speed on an on ramp etc)
Thanks
dave
