Alright so i just bought a new truck with a rod knock'n 22r. Pulled the oil pan today and found the #4 rod has lots of slack which i expected. I also found a heap of parts sitting in the oil pan.. obviously a broken timing chain guide, it has some pretty major grooves worn into it too. There was a little spring about 1.5" long and 3/8" in diameter is that part of the timing chain guide? So can just replace the guides? Or should i do chain and gears too? What would you guys reccomend? Thanks!
