My 2010 is having the dreaded timing chain issue, but with 130k miles, I am past warranty, so doing on my own. Not willing to spend the shop money on this after having had the piston issues as well as a tranny replacement at 80k miles on this POS. As I will be near the water pump, would you recommend replacement at this point? I am not sure how long they tend to last, but would hate to have it go out shortly after completing this job. Pros/Cons? Thanks for feedback.
