I have a 2015 RAM 3500 6.7 Cummins with 190,000Km. It is entirely deleted with Warp tuning.
I did an engine service yesterday and noticed metal flakes in the fuel drained from the fuel filter closest to the engine.
I then cleaned the drain pan well and replaced the water separator near the spare tire.
I found some metal in it as well.
It has been relatively cold the past weeks -8°C, and my truck has been smoking and mistaking upon start up, but this happens every winter, and I can't seem to change that.
I have always run fleetguard filters and done regular maintenance, changing the fuel filters once -twice a year (about every 12-15k KMS).
Does anyone know of any testing to determine if it's the low-pressure or the high-pressure pump?
I cut open my fuel filters last winter and didn't notice any metal, so this has happened this year.
