lubricating the injectors and IP
My 7.3 makes a knocking noise when its running. I was told that I shuld drain the fuel filter and fill it wit atf fluid and let the truck run. They said it will lube the IP and injectors and shuld fix my knocking problem. Is it safe to do this and will it fix the knock.

everybody knows atf is a solovent. works great as one. never had an issue. i will put almost anything into the tank on my 6.9( atf, WMO, hydro) and NEVER had a problem.
i will normally fill the filter with dieselklean or the like, but every now and then throw a filter full of atf at it. quiets everything down.

What could be happening is one of your injectors isn't closing completely and leaking fuel into the cylinder. The knock you hear is a result of the precombustion. I am having this problem with my truck right now as well. Unfortunately for me my DMF is so worn that disabling 1 injector causes it to make so much noise that I cant tell if the knock has gone away.
