    2001 HPDI maintenance

    Taking the old Yammer Hammer to the shop. What are some things i should have done. Have had zero issues with this motor. I am the original owner. Can a report be ran with this motor? I have done very little to it. Thanks in advance

    Filters, all of them. pull and flow test your injectors. Compression test all cylinders. Run diagnostics. Fuel/water separator if you don't already have one. Clean and properly functioning fuel system is the life of your HPDI. I have an '05 series 1 300. No issues yet but I do this service every 100 hrs.

    If you use fresh non ethanol fuel you can go 1000 hours on a set of filters
