Things to look for before you buy it...
1.) First and foremost, pull the air induction tube off of the turbocharger inlet (big black rubber pipe that comes from the air filter box and necks down to the turbo) so you can see the compressor blades on the turbo. They should be shiny and SHARP. I mean, sharp enough to cut you if you pushed hard. If they are dull, pitted, bent, broken, etc, then the engine has taken on dust, and it is most likely wrecked. If there is lots of dirt inside the tube, this can also be an indication of the airbox leaking in dirt. Check the airbox for broken tabs where it holds down on the filter. Any of the above and I would run away.
2.) If it is an automatic, it should shift crisply and quickly. Smooth, slow shifts are bad, it means she is about to roach. Smell the fluid, it should not smell burnt at all.
3.) If she is a stick, then the tranny should shift smoothly, clutch should disengage fully when you push it.
4.) Put her in 4x4 and listen for bad noise. More noise is not necessarily bad, they do make a little noise in 4x4, but if it whines, grinds, or whirrrrs, then you gots problems.
5.) Check the oil. It can be black, but it should not have water or be brown or milky.
6.) Buy yourself some SCA strips to test the coolant for SCA. If the truck has no SCA in it, then you can only assume that it never had SCA in it, and then you are taking your chances with a cavitation problem. (BIG $$$$$)
Then just do the normal. Look for leaks, listen for odd noises, you know the routine. Good luck, and welcome aboard...
Oh, the WHoosh at high idle is the Exhaust Back Pressure valve. Totally normal, it is just a device that helps the truck warm up faster...

Then I went to replace the EBPV sensor, and noticed that the tube coming up from the manifold was broke so I replaced both the tube and sensor(factory parts not exactly cheap) Didn't fix it-mad I heard about a sensor bypass from another site so I bought it (only like $35.00) and still no fix
Finally I figured out that if I just leave the sensor unplugged I have no problems. Not the solution I was looking for but seems to work for now. If anyone has any suggestions let me know, PLEASE!!!
