There’s no denying that setting the timing on a Dual Overhead Cam (DOHC) engine is precise work that directly impacts valve timing, combustion efficiency, and performance. Understanding how to set timing on a dual overhead cam engine is key to getting peak output. Proper engine timing
You’ve seen “DOHC” on an engine spec sheet or heard it mentioned at a parts counter—but if you’ve never really looked into how engines are built, it probably sounds like alphabet soup. Spoiler: it’s actually pretty straightforward, and once you get it, you’ll start to see
If you’ve ever had a camshaft bolt snap or shear off, you know the damage isn’t just inconvenient—it can be catastrophic. Whether you’re a shop owner, a DIY diesel tech, or just trying to figure out why your camshaft bolts failed, it’s worth taking a closer
If you’re running heavy-duty machinery, head gasket failure isn’t just a mechanical issue—it’s a major disruption. A failed CAT head gasket can lead to coolant leaks, loss of compression, and even catastrophic engine block damage if left unchecked. Whether you’re managing maintenance of a fleet or
If you’ve ever popped the hood and wondered what actually controls the rhythm of your engine, the cam shaft is a good place to start. Whether you’re dealing with a diesel-powered workhorse or a standard gasoline engine, this component is critical to how your internal combustion
There are lots of reasons why diesel is still king in heavy-duty applications. A well maintained diesel engine can last for ~1,250,000 kilometers (800,000 miles), but even the most optimistic lifespan figures need to be taken with a grain of salt–maintenance and usage habits play a
With so many costs on the rise, it’s natural to look for DIY solutions when it comes to keeping your vehicle on the road. Why risk a big labour bill if you just need to replace a broken part? Well, depending on your problem, that approach
When it comes to keeping a diesel engine running well, it is often said that cylinder heads are the most challenging components to deal with. That’s not just us saying that; scientists from around the world have studied the issue of cylinder head durability and come
A cracked, damaged or warped cylinder head can take any vehicle off the road. Whether due to incorrect maintenance, repairs, or even production and manufacturing issues (no manufacturer is immune, as the latest BMW recall shows), a warped or cracked cylinder head needs to be addressed
Vehicle repairs aren’t getting any cheaper. In fact, the average cost of motor vehicle maintenance and repair in the U.S. jumped by 6.5% in 2023. With rising costs, it’s no surprise that mechanics and DIYers alike are looking for ways to save where they can. When
