If I remember correctly, I believe there were around 105K - 110K miles on mine when I did the Valve Covers. My Tracker was my middle daughters first vehicle. Bought it with 78K, third owner, was used as a flower shop delivery vehicle, and records stopped after warranty ran out.Thanks for the tips Shrimpy. Out of curiosity - if you did yours 6 years ago, how many of your 183k miles have you put on since then? Mine only has 116k on it now, and I really hope I can coax another 150k-200k out of it. Much to my wife's chagrin (this will be her car), it's taking longer than I'd hoped mostly because every time I work on it, I find something else that falls under the category of "that would probably be fine but really ought to be fixed now". ?
