Kent is hard at work on his new series of advanced D.I.Y. mechanic series of manuals. The challenge for him has been trying to make the advanced technical side of the information still understandable to the average home mechanic. For example, explaining how to use electrical testing meters to test the function and health of a diesel pre-glow system is not an easy task. Describing how to fine tune the vacuum adjustments on a diesel automatic transmisson is even more difficult.
The new manuals will be printed and wire bound in a larger format (8.5 x 7 inches). This will allow room for more charts, schematics and larger pictures. Knowing that these manuals will be handled often, we are adding a plastic cover to help minimize grease spots.
Along with radiator neck failure, the rupture of one of the large oil cooler lines on your diesel engine can easily ruin your engine. When one of these lines goes you can lose all your engine oil in just a few minutes. If you are driving and not watching your oil pressure gauge you can destroy the engine bearings in short order.
If you lose your timing chain you will destroy your engine. The pistons will come up and hit the valves and at speed can push the camshaft(s) right through the valve cover(s). There is no set recommended mileage at which you should change it.
