98 Voyager 3.0L V6. I may have found the answer to the notorious 3.0 L Mitsu Motor Lifter Noise. When doing an oil leak job on mine, I decided to redo the pan gasket. With the pan off I discovered the oil pump to block gasket had failed. I replaced it. Since then I have not experienced the lifter noise even after the Voyager has been sitting out overnight in sub-zero weather. Coincidence? Perhaps. But the proof is in the sweet silence! Peter
