Injector #8 failed Cont. test

[cpayne6335]

Hey,

Today I did a buzz test on a cyl. Cont. test. Buzz test passed, and all injectors sounded the same. Then I ran a cyl cont test, and the TE scanner said the test would last 4 minutes, and only lasted about 1 min, and thena screen came up and said Cyl. 8 failed. The main mechanic at the shop said Cyl. 8 fails most of the time, and it may not be a big deal. I can not hear a missfiring.

another problem is blow by. I see some smoke coming out of my oil fill tube when I add oil when it is running. I also get enough smoke while at a stop, I can see it coming out from my wheel well. I did move the CCV tube to dump under the driver side leaf spring.

No related codes came up. I am still wondering about MPG. I just got 13.2 MPG. Not sure if that is good for a 99.5 CC LB 4x4 dually auto truck that wieghs close to 10k. gears are 4.10 Stock for the most part.

Thanks for the help...

Mileage isn't too bad for that size truck.

Don't worry about the injector, it's a long lead. Mine has never passed.

I don't like the sounds of the blow by. Can you flip the cap over and set it on the fill tube and it won't blow off?

umm.. some how it creadted 2 threads..... I tried that, and the cap moved because of viration. I did find a plastic cup and placed over the tube, and it did not move or let the smoke out, so I am guessing the blow by is not that bad yet....
