Diesel fuel in crank case
Chevy Mechanic: Pete, Auto Service Technician replied 8 months ago

Did this only occur after you replaced the injectors or was this an issue before and after?

Diesel fluid is going into crankcase after new injects have been installed. The old injecters were gummed up preventing engine from starting. New injecters work great. Engine runs extremely well. The problem is now doesel fluid is getting into crankcase. We are going to have to open engine back up and figure out how to warrenty the work.
Chevy Mechanic: Pete, Auto Service Technician replied 8 months ago

O.k.,it sounds like at least one of the injectors is faulty.I have seen some of these new or with few miles on them fail so soon like this with the affected injectors needing replaced under parts warranty.If you have a scan tool you can sometimes check the fuel injector balance rates to locate which ones are needed.

With the engine warmed up the injector balance rates should be at 0 plus or minus 4.Any injectors beyond this will need to be replaced to resolve this fault.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service,your 5 star rating is appreciated ( should be a link to click on here or above).You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.

Thanks Pete
