DJ Truck Repair

Just to let everybody know because there is another forum in here about the same issue, but there was no resolution if you replace the head on a D13 volvo or a mp8 Mack and it has a fuel knock you have to log in with ptt and reset the contribution balance on each injector.

I have a 2013 mp8 Mack. Same engine as D13 volvo. Came in shop with burnt valve on number 1 cylinder. Owner decided to replace head and declined to change damaged liner due to where the damage was. After head replacement had a fuel knock on same cylinder valve was burnt on. He stated that the knock was happening even before the burnt valve and decided that since truck had almost a million miles he wanted to rebuild it. After rebuild fuel knock is still there. I swapped injecters around and fuel knock stays at number one hole. I’ve checked all rocker arms and plunger for Jake’s and everything is good. I’m out of ideas. Can someone help me here??? Thank you!

Did you ever find out what the issue was??? I have the same problem and it’s driving me nuts!!!
