if a disco is still running at 150K does that mean most of the major issues have already been sorted? thinking a high mileage disco may not be a bad thing...

 

You can always have a dealer check based on the VIN, but that would only show repairs done at a dealer. Without that or receipts from the owner, there's no way to really know.

 

Whenever looking at a used truck, I always bring along a spark plug wrench so I can take a look and one of the plugs, as well as have a look at the PCV system. If both are in good order, and all the visible maintenance items seem upkept, and no obvious noises of concern - then it becomes a "candidate". If it isn't up to snuff at that point, I don't even bother with a test drive. If a candidate passes a test drive, then it becomes an "approved candidate".

 

I bought my D2 with 150000 on it and it had alot replaced.I did have to do the head gasket and front prop but(knocking very hard on wood) Ive got 167000 on now and she runs like a top.I would just try to find out as much history on it as you can ie carfax,lr dealer service and take your time going over it and checking it out.

 

I bought mine with 152,change and now she is at 186,change with less than $1000 in repairs.
It is always buyer beware, if you are serious about a certain one have a mechanic look it over and write everything down that needs attention.

 

Suede, What do you do to check the PCV system? just make sure there is air flow through it? or is it more extensive?

 

On a DI it's simple. Unscrew the PCV cannister from the passenger side valve cover and tap it on the ground to see how much soot falls out. Then put a napkin over one end and see how easily you can blow through it. It should be easy to blow through, requiring almost no more effort than if nothing were in there. And squeeze the hoses to feel for the crackling of built up carbon.
Then with the truck running, remove the oil dipstick to see if smoke pours out - indicating backpressure. Generally, if the PCV has been maintained properly, then the more basic items, like oil changes, have likely been maintained as well.

A well maintained PCV, along with no issues detected by the state of the spark plugs, is usually a good sign.

 

like spike i bought my truck with pretty high miles... mine was in a bit of a sad state, but after some work and little things here and there mines still runnin strong with 176000 miles and counting... i drove to kansas in november with no issues something like 1600 miles round trip
