I wear my bill curved
Need some advice on this thing. Its a 04 Excursion 6.0. Customer drove it about 50 miles, was running ok until she got on it to pass traffic. Said it bogged down and had no power. Shut it off when she got where she was going, and that was the end of it. Got it to my shop, checked oil level and codes, P2291? in memory for low ICP. Unplugged sensor, still no start. Replaced the oil filter because the part numbers on the filter and the lid didnt match. Also found there is a little black spring loaded button on the top of the stand pipe right in the center. One of its "legs" is broken off, but you can set it in place and it will stay. What is that peice for?
With the new filter in place it started. Crank time was a little long, figured it might have some air in the HPO system. Let it idle and warm up and took it for a drive. Runs smooth, but no power, ICP doesnt match desired ICP and the oil pressure gauge drops to zero. Air tested the HPO system and cannot hear any air leaking with the IPR energized any where above 20% (125psi) Im going to get a mechanical gauge put on it to verify lube pressure. I have read about some ball bearing in the HP pump coming out and causing low lube oil pressure? If thats the case would I hear it when air testing? Do you think I am looking at at a HP or LP problem? Thanks for any ideas.
