[04 f250 6.0 2wd] today i did the first oil change on my dad's 250. it's got 86k mi on it. did all the research on 'properly changing the oil' and filled it with rotella t3 15w40. afterwards i started it up and it ran like normal. oil pressure and all gauges were normal. parked it, and came back out 20 minutes later and there was a puddle the size of a Frisbee under the truck. looked underneath and it seems to be coming from a silverish looking piece between the turbo and the oil pan on the rear of the motor. i guess you could say it's pretty much in the middle of the engine. wondering if anyone has a name for this piece, or if this oil is causing the leak. any help will be much appreciated.
