87k. Just removed and cleaned
87k. Just removed and cleaned egr cooler, valve, pipes, intake manifold, and installed an oil catch can. Was partially clogged with black carbon soot. Tough to remove but doable. New pcv valve. Changed trans. Fluid. Changed coolant; now thinking I should have done water pump also. I have changed oil every 5k since new, always to the full line. Will fill to half full level from now on to reduce oil going thru pcv
