Im at 210K on my original 3V with orginal phasers etc... I do have the chain rattle on cold startup.. Oil tensors leak down overnight. Only reason I haven't fixed it is i'd have to do the timing chains, phasers, etc when its torn down that far.. Even doing it myself its like a $3k job. Don't see me putting that into a motor with 200K on it when a new unit is in the $4k range.
The old 2V in that expo will run forever if it doesn't send the #8 spark plug through the hood... Go ahead and invest in a helicoil kit if it hasn't already been repaired.
