Help: fuel in crankcase

[dmax1]

My crankcase is filling up with fuel. Not sure where it's coming from. I know there are a couple things that will cause this and was wondering about other symptoms to look for. The truck was running great when this happened and continued to until I got it home. The oil pressure dropped to about 20# and it had a rough idle. Any ideas guys? Appreciate the help.

Are the ballence rates ok? if not and injector make be partly or fully stuck,if its an lb7 check the return linecheck to see if lines are tight you might have blown an o ring on the injector and its spraying under the valve cover

How do I check the balance retes of the injectors?

Does your truck have efi live? If not dealerships can check it

More information on the truck would help. Year, Make, Model, any modifications?
