    compression in an '04 225 HPDI??

    Wondering what compression numbers should be normal in an '04 225 Vmax HPDI? I know all 6 cylinders should be within a few of each other, but what should those numbers be? Thanks!

    If I remember correctly (iffy) mine were 110 lbs. I do remember they were exactly the same which was a pleasant surprise.

    Thanks again, Champ.

    Is there a standard number in a book or manual somewhere that the compression should be for a motor or does it depend on model / individual motor?

    115-120 on hpdi or ox66 but I didn’t get that from any book just from my experience.
