I crawled under the old bronco and replaced main and connecting bearings on my crank after noticing a knock and a drop in oil pressure after a long trip. As you know its a pain in butt to do on your back so when I was finished it leaked from the rear of the pan. I was tired and brought it to a mechanic to re-seal the oil pan lazy I know. When he returned it there were no leaks but low oil pressure. I questioned this but he convinced me that my crank was lobed spun the bearings and needed to be replaced, so got pissed and parked it for about 8 months. The other day my wife bugged me to fix the truck so I crawled back under it to remove the oil pan and when I went to lift the motor the motor mount bolts were just dummied up. I started on the pan and noticed to miss-matched bolts, so now I'm getting angry. I started feeling around the oil-pump pick-up tube first for trash and worked my way up to the pump and when I did I noticed the pump had about a quarter inch of play in it. I could see the amount of slack in the retaining bolts. I went back over to the shop but the mechanic had been fired a few months ago sparing me a homicide charge. Thank you to all the honest mechanics on this site for all the help over the years, next time I will not be so lazy.
