it has one not-so-great injector, balance rate test shows a 4.8 in D. the tailgate is slightly bent. smokes a light blue haze at idle and when throttling it, can't notice it when driving. 150K miles. fuel gauge works intermittently and throws Fuel Level Sensor Circuit code. i figure it's just a loose wire or something easy. the smoke- i wouldn't doubt it's valve seals. unless the oil pump putting out too much pressure would cause this (40 at idle and as soon as pedal is applied it goes to 60-75 and stays there till full throttle and then it goes full bore to 80)?
on edit: KAT, can you enlarge these? they are dieselplace links and i can't figure it out
