It’s been a fun day working on my truck, and I thought I’d share a few pictures.
Some background: I’ve noticed an occasional knocking at idle and under heavy acceleration, which can be caused in a diesel by a leaking injector. A fellow DMS member was kind enough to lend me a scan tool which confirmed a negative fuel balance rate for one injector, and allowed confirmation of the diagnosis by shutting that one off and observing that the knock stopped.
I ordered a new one from Injectors Direct and installed it today. The truck is purring like a kitten again!
The old one, buried back behind the fuel hoses and glow plug controller.
Several extensions and a crowfoot flare wrench were required.
Old injector, new injector, the hold down bracket, and the old fuel line.
Grimy injector bore before cleanup.
New injector, installed and ready to test!
