12.7 detroit series 60----looks like i have fuel in my engine oil

If you take a drop of that oil. and place it on a piece of clean brown cardboard, watch for a ring to run away from the dark oil spot in a few seconds. If it does there is deffinately enough fuel in the oil to be of concern. This has been proven with our oil analysis machine. BRS is correct in my view, as whenever there was fuel in the oil without performance issues, good money always won on fuel coming from the solenoid area.

 

The one time I had injector seals leak. Supposedly it was injector seals. Fuel was going in to the coolant. Filled the reservoir up to full. That was on a 2012 FL.

 

Update!!!!!


Oil sample 1 6.3% fuel in oil
Oil sample 2 1.3 % fuel in oil(different lab)

Removed valve cover and left Jake's and the rockers in place. Pressurized fuel system to 80 lbs. Pressure dropped immediately!!!! Lost 10-15 lbs in under 30 seconds keeps falling and falling. Still can't see which injector is leaking. I can hear it leaking i just can't see it. Of course with cyls. 4,5,6 under the cab it's hard to see. Would taking the Jake's,and rockers off make it easier to find leak. Im hoping it's just o rings. Injectors where replaced roughly 200,000 miles ago.
