0 Mackpro Posted December 12, 2022 Share Posted December 12, 2022 On the common rail engines there is lots of planes under the have cover to leak . If no one has been into the injectors then probably not the injector lines . There is a service bulletin on this issue and have seen this first hand . It was only on the Common rail MP7’s. The is a plug left loose in the back of the head behind the cam gear. Message me your email and I can send you the bulletin Quote Link to comment https://www.bigmacktrucks.com/topic/70862-a-lot-of-fuel-in-oil/#findComment-518050 Share on other sites More sharing options...

0 fjh Posted December 12, 2022 Share Posted December 12, 2022 If Pros fix don't do the trick ! here is a remote possibility it is an injector however pros fix is more likely we ran into this several times u need to use die to find the issue!
