I know this probably isn't the place to ask(nissan forum lol) but the same guy has a 99 4runner with the same amount of miles for only 3k as well. Trying to decide between the two.
The power valve screws are actually quite easy to do. Should take you less than about 2 hours to do them. You just have to be VERY careful when you remove them (one at a time) so as not to drop them down the intake. I would suggest that if you decide to do the powervalve repair that you go ahead and get a little further into it and replace the water control valve. It sits just below the intake on the rear of the engine and is impossible to reach without removing the intake (you are already half way there with the power valves). The water control valve is a fancy name for a thermostat that controls the flow of water out of the lower engine block. If it fails the engine will overheat in seconds before the gauge ever registers anything. The temp gauge sending unit is beside the water control valve on the water transfer pipe (2 sending units there, one is for gauge and other for ECU.) I had to hit the Stealership for the water control valve as no parts stores had it but the cost wasn't too bad at less than $15.
I was looking at a 4Runner before I picked up the pathfinder. The Toyota's have a very bad tendency to blow head gaskets. Look around on craigslist and you will find that about half of them are selling because of blown head gaskets.
I picked up my pathfinder with about 200k on it and started having issues with it pushing coolant out at highway speeds (it runs fine around town.) I would suggest that if you are looking at a pathfinder you make sure to get it on the highway before purchasing it. Look at the coolant level in the overflow and then Run it at least 10 miles with the A/C on and check the coolant overflow afterwards. If the level has increased then you may have issues with it.
