In diesel repair, most people focus on one thing:
Getting the part.
But here’s what actually determines whether a repair succeeds or fails:
- Was it the right part?
- Did it arrive on time?
- Was the root cause identified before installing it?
Because the truth is:
A great part doesn’t fix the problem if the process around it is broken.
That’s where your diesel parts supplier becomes more than just a vendor. They become part of your diagnostic process.

You may not realize it, but there are a lot of components that make up the cylinder head of your C15 ACERT. If you have a failure in that part of your engine, you might be inclined to blame it on your cylinder head, but it’s possible that one of these other components could break. This would lead to problems with similar symptoms to that of a failing cylinder head.

Connecting rod bearings are one of the smallest components inside a diesel engine, but they play a massive role in long-term engine reliability.
Improper bearing selection, incorrect oil clearance, installation mistakes, or inaccurate measurements can quickly lead to oil pressure loss, crankshaft damage, metal contamination, bearing failure, and catastrophic engine damage.
That is why connecting rod bearing selection should never involve guesswork.
Proper bearing fitment depends heavily on crankshaft journal measurements, housing bore condition, oil clearance verification, engine application, and the condition of the surrounding rotating assembly components.
Quick Takeaway:
Connecting rod bearings must match the exact crankshaft journal size, oil clearance requirements, and engine application. Assuming “standard” always fits can lead to serious engine damage.

Problems with CAT C15 Diesel Engine Oil Pumps
Your oil pump. It’s probably not a part you’ve thought about a lot, but it serves an important role in your diesel engine.

A turbocharger failure can look like a bad part.
Loss of power. Smoke. Noise. Oil leaking. Shaft play.
But in many heavy-duty diesel engines, the turbocharger is not the real starting point of the failure. The damage often begins somewhere else in the lubrication system.
The number one issue that destroys turbochargers is oil starvation. When a turbo does not receive a steady supply of clean, pressurized oil, internal damage can happen fast: sometimes within seconds under load.

If you run trucks, manage repairs, or budget for diesel work, fuel price changes matter fast.
As of June 01, 2026, the global average retail diesel price was $1.56 per liter, or $5.91 per gallon, according to GlobalPetrolPrices. Their dataset notes that some countries are updated weekly and others monthly, depending on how their fuel markets are regulated.
What stands out most is not just the average. It’s the spread.
On the low end, a few heavily subsidized or regulated markets were still posting diesel prices near zero in U.S. dollar terms. On the high end, some developed markets were above $2.50 per liter, with Hong Kong above $4.50 per liter.

We all know how important camshafts are to engine performance – and when they fail, the damage can go far beyond the camshaft itself.
Whether you’re running a general diesel platform or a Caterpillar C15 diesel engine, one of the most common issues is camshaft lobe wear and pitting.
👉 And once it starts, it does not slow down – it accelerates.
