Let me know the details on that when you do it. I just turned 148,000 miles on my car today and was wondering when I should replace that timing chain and water pump. If I may ask why are you doing the oil pump? I have heard when you do the timing chain and water pump, its a good idea to do the thermostat as well. Could be wrong but its what I have heard. Best of luck my friend.I've got 185,000 on my 2006 with no major work done. Im about to do my timing chain, water pump, and oil pump. Other than that just small things like manifold/valve cover gaskets, EGR valve, oil pressure sensor and a replaced PCM.
