Pulling injectors on a mack mp8 #mack #mp8 #injectorcups #fuelincoolant #fueleatsrubber

Pulling injectors on a mack mp8. This is the same job as previous videos with the oil cooler and broken and swollen gaskets were found… then we found fuel and coolant mixing. We proceeded to pull the injectors since I was already removing the valve cover to reseal the oil leaks. Found number 2 and 4 Injectors cup orings no good… and number 4 injector to cup seat blown out.
