Today we end our three part series on Part 3, “How Diesel Engines Work” with this final video that covers the valve timing diagram of a diesel engine. Missed the first two parts? Simply check the posts for the last two weeks.
Today I’d like to talk about the simple oil change. The oil change itself may be simple, but there’s some pretty important things to know about preventing oil sludge. Oil eventually turns into a jelly-like sludge. Now, sludge clogs up oil passages and keeps oil from getting to some areas of the engine, causing parts to wear out prematurely, and that means expensive engine repairs. That’s why you need to change your oil and oil filter on schedule, to get the old oil out before it turns to sludge.
