Rawze.com: This is a multi-part series on me disassembling my engine and replacing the pistons, liners and such after the head developed a minor coolant leak at one of the injector cups. The engine had 955,890 miles on it (close to a million miles) and it has always been good to us with high fuel mileage. It is not a how-to series, but just simply a vblog of me working on my own truck. You should not try this yourself without professional guidance.
