Agreed Paragon, I'm not big on coincidence either. But there just isn't much they can do on an oil change (especially with me watching over them) that would cause this. I think the pick up could absolutely cause these symptoms. The pick up is just a tube from the bottom of the oil pan up to the bottom of the oil pump on the front of the engine with an O-ring and one bolt holding it tight. Now if that bolt started to loosen, and with less "suction" from the oil pump at idle to hold the O-ring tight, bam, less oil pressure. I've always noticed that the most common time for the 20 psi @ idle was sitting in my driveway on an incline waiting for the garage door. Hmmmmm. Then with all the offroad vibrations yesterday I wonder if the bolt backed completely out but the pick up/O-ring was held tight from pump suction until I shut down, then it virtually fell off the pump. Because whatever happened it happened between shuting the engine down and starting it. Make sense to you???
