I've been the original of both motors since new in 2009. Other than an alternator, these two motors have been flawless. I did the thermostats and VST's, about 100hours ago. But other than that, I've not done anything to these motors. I'm ready to do whatever they need, but honestly, throwing parts at a motor seems a bit silly if they run like clock-work. I know that I may take some flack for not changing more, but, now I'm ready. I have been religious at performing Oil changes with pure synthetic. I know it's a waste, but, I really don't mind. It's something I can do. Everything else it goes to a dealer.
Plugs is about all I can think of.
