Odd leakdown test results...

[dhirocz]

So on Wednesday I did an injector leakdown test with the Cummins tool. It showed me I had a pretty healthy leak coming from the back bank, so I put an injector on order. Engine was cold at this time.

Today, I did the test again to verify which injector it was, and I cannot get it to leak. At all. Both banks are solid as a rock. I did notice though, the front metering actuator was a bit warmer than the rear.

Is this a normal occurrence? I just ran the test, engine is still warm from driving home however...maybe 140 degrees.

Mileage has dropped again recently, but aside from waiting for it to cool off again and hoping it leaks, what else can be done?
