My truck (208k on it) recently ended up with water in the oil. Looks like the timing chain bit through the jacket because of broken guides. I've already got the head to the machine shop, and am taking the opportunity to do the timing chain and all the gaskets of course, but was recommended by the guy at the machine shop to do the rings, even if they don't show any outward signs of destruction. My goal is to get out of this as inexpensively as possible, because while I love this truck, it's just a spare/work vehicle, and another 20-25k miles would translate to a few more years on it -- it's not my daily driver.
So my question is whether I really should spend the $$/time on redoing the rings given my goal, and whether anyone else has any other advice they'd like to throw in while I've got the thing torn down now.
Thanks in advance.
