Anybody notice the high pressure pump?
look familiar ?
CP4.2? like the Ford and GM diesels, but from what has been reported they have worked the bugs out on these pumps. Have not seen any new posts about them in a long time. The ceramic coating was the issue and unlike the CP3 when the CP4 goes south the metal fail out gets set to the injectors taking out the whole engine. In the CP3 the metal fail out heads back to the fuel tank not the injectors, saving the engine.
