Coming home from the river last night, 4 hour trip pulling 17' boat, doing about 70,gauges not showing excessive heat,I noticed i was losing oil pressure. All my oil had blown out the pass by tube. I am also smelling diesel. Burnt or lost alot of fuel comming home.after adding more oil and letting cool...It starts fine and has proper oil pressure butt loss is brought with rise in temp.Idles rough when temp is up. What did I do And what should I do. Please help...... Thanks Steve

Dealer replaced all 8 injectors,gaskets,fuel filter, oil and filter. All warranty. I am So verry greatful for that, BUT when they brought my truck out to me, right away I noticed oil pressure off the scale at about 4 o'clock. Imediately i pointed out the problem and that it was working when I brought it in. They told me that I could leave the truck and they would check it out tomarrow but that would not be warranty repair work.I called GM and the are working on it with the dealer,but might it be an easy fix I can just handle myself maybe?I dont want to leave my truck another week with a pissed of dealer.
when I shut off truck , guage drops down to about 60.If clues help, Guy from GM asked if fuel filter had been changed when I told him oil pressure guage was wackoo.Whats the relation?
