I'm at a ford dealer and they have pulled the LPOP off and it was all chewed up and they drained the oil and lots of metal pieces in it. They are tearing the engine down in the next day or so to be 100% sure but all the techs say it's the needle bearing and I'll need a new engine. I guess they've seen several had one just last month.The tech says he's going to fight for a whole engine not just a short block. This is also under warranty since I have the 200,000 diesel care. This is a 2007 F550 that is always under a very heavy load. It's has 146,000 miles and is maintained only by Ford. My main question is should I be getting a whole new motor/reman or just the short block? I've lost so much work because of this engine over the years I just want whats right and don't want to be taken advantage of. I'm no mechanic myself so any advice would be great? Also any thoughts on the reman motor and quality? Thanks in advance. Also thank you all for so much for great info on here I've learned more than I ever thought I would!
