🔧 When the problem isn’t where you first expect it…
This M62 engine originally came to us as a non-runner. Around a year ago, we stripped and rebuilt the engine, carrying out crankshaft shell bearings, an oil pump and timing chains before putting it through an extensive road test.
A few months later, the vehicle developed a fault with the Bank 1 inlet VANOS system.
With the engine back apart, our plan was to inspect the camshaft and, if everything looked as expected, replace the oil control rings.
But this is why proper diagnosis and inspection matter. 👀
We found that a section of the camshaft casting where the oil control ring sits had broken away. That damage was allowing the VANOS system to behave incorrectly and simply replacing the seals would never have solved the underlying problem.
The solution was a new inlet camshaft, along with the associated gaskets and components required to put everything back together correctly.
The vehicle is now back on the road and, so far, so good. 🤞
It’s a good reminder that sometimes the fault isn’t the component you initially suspect and that’s exactly why we take the time to properly strip, inspect and diagnose rather than simply replacing parts and hoping for the best.
Diagnose it. Find it. Fix it properly. 🔧
