    2.4 Turbo spun rods

    I finially disassembled most of my srt4 engine. Cylinders 1, 2, and 3 all had spun rod bearings. Rod 4 the bearing looked fine other than a few pieces of junk in the bearing ( from the metal in the oil). All of the mains are fine. It was still difficult to spin the crank with the rods disconnected so I figured it spun the mains but they were fine. I am guessing something happened to the oil pump and put metal in the oil taking out the bearings. If it was run out of oil I would have expected rod 4 to be the worst and get better as it gets closer to the pump, but this was backwards. Has anyone ever see this happen on one of these engines?

    Ive heard that its common for the oil pump to break, Ive also heard that UDP can cause it too from the harmonics.
