LB7: Fuel in the oil after new injectors

[WolfLMM]

I'm guessing I have leaky return lines Any other ideas?

Who's injectors? Only thing you can do is pull valve covers, run the truck and ramp up rail pressure to see if it is a return line or cracked injector

That sucks bud. Bad injector body maybe but more likely a return line...

I did one where I left a return bolt loose driver side.. Pulled passenger side first and didn't find it..

On the plus side the oil was clean

New GM injectors, from SoCal diesel. Got a few different issues going on right now, all fuel related.

Check return lines sadly see where that takes you.. Or make sure the feed lines are tight. Would cause hard/ no start though I would think.

The one I goofed on ran perfect until it started blowing diesel out the Pcv.. Only took about 5 minutes of running too...

Humm okay. Well I've got about 5,000 miles since injectors, and only a very very small amount of diesel fuel in the oil. I have a very small leak I guess.
