We changed out our IPR in our 2000 DT466E because of it leaking. Replaced with new and we get loud rattling and 164FM10 (333) error. Changed IPR whip, IPC and still nothing different. Tried another IPR with the same results. Would appreciate any help.
Is the loud rattling with the engine running? You said the reason you replace it was because it was leaking. If you put the old components back in does it run ok except for the oil leak? If the engine does not run you may have lost the prime at the HPOP, put a gauge on the outlet and test.
