my oil pressure is around half way at tick over and moves up just past the three quarter mark when revving,if its not in limp mode its safe to say no1 injector is ok,take it for a test drive and make sure it revs up ok,if its in limp mode it will not pull very well over two thousand revs,if its ok it should pull well after 2 thousand revs,not had any major problems with mine,first thing that ever went was the heater blower,that was the heater resistor thing in the duct just past the blower under the dash on the passenger side,all i did was resolder the connections on it as the solder had melted,that was few years ago and its still fine,another problem i had was intermittent starting problems,that was the glow plug relay,i opened it up and again noticed bad connections where the solder had melted,just resoldered them and its never not started since,cant think of anything else that the 2.5 is prone too
