what test will they run to see where the fuel is coming from in the crank case\
\
thanks for any ideas

 

I don't think there are any other than visual inspection.

Its either injector bodies cracked or o-ring on the CP3 gear.

I have used dye in the fuel before but you have to use a lot and you have to run the engine with the valve cover off (kind of messy) for the injectors and with the pump gear access cover off of the front geartrain cover.

 

now if its and injector wouldnt thier be noise or bad performance something noticable

it goes in tuesday and just nervous about it
