[QUOTE="444getsitdone, post: 1246432, member: 1882"] How many miles on this thing? Unless he neglected his oil changes (never happens!) I'd not guess the HPOP, possibly IPR, unlikely.... pull the VC's and check the injectors, are they spraying oil everywhere? The cold thick oil does not leak as much and the HPOP can keep up with the loss, once it warms up the thin oil leaks a lot faster, faster than the HPOP can keep up. I work on the Caterpillar HEUI's quite often and the HPOP do go out on them quite a bit but the things have a lot of hours on them, and the owners dont always know about oil changes... Dead head the HPOP if you think its that, then you know for sure if it is (or is not) the HPOP. 1600 PSI is not bad for the pump, 80% duty is high but its trying desperately to make more pressure. I think youre losing it somewhere else [/QUOTE]
