high pressure line

[atomic]

I have an 04 LB7 and had new injectors installed along with return lines. They where vac tested and now I still have diesel in the oil pan. The mech. said the high press.lines looked good and reused them. Is it possible that they are leaking under the valve covers?

if your getting fuel in the oilpan then its under the valvecovers
its most likely the return leaking
heres how to check the returns for leaks

Off to the the garage with the lap top to try that out. I'll let you know what happens.

return lines check out. Took off one injector line and it is a little distorted and could be the culprit. Will take more off and let you know what I see.
