Just following up on an item for a friend. He has a 2005 F250 with the 6.0 Diesel. Over the past month it has been progressively harder to start when it was warm. (starts fine in the morning or at the end of the day when it was cold) He took it to the dealer and they diagnosed it as low oil pressure with the corrective action being the replacement of the high pressure oil pump. Long story short (and $1600 later) when he got the truck back it was doing better but still seemed not right. Bled air from the fuel system and all seems okay. Has anyone else had this "Bad High Pressure Oil Pump" diagnosis? Seems a little strange but I can say I am an expert (I have a 2000 F250 w/V10).
The HPOP has been a problem, and so has the fitting that holds the oil line in place. It is not as common as the EGR Cooler. STC fitting how many times did ford revisit that one.
A LOT of HPOP's are replaced unnecessarily simply because of the STC fitting failure and incorrect diagnosis OR a tech too lazy to properly diagnosis the problem. I've never seen any discussion that the later HPOP's were a problem....more like virtually bulletproof.
