What happens when an engine fails? We identify the signs of a blown head gasket and coolant intrusion. We then walk through the restoration process—from inspecting the crank journals to the benefits of professional cleaning and re-ringing for long-term reliability.

We dive deeper into the N62 engine to examine the complex timing chains, eccentric shafts, and variable valve timing systems. See exactly how these components work together to deliver that signature torque curve, and learn what to look for when inspecting internal wear.

Engine failure nightmare! We’re tearing down an 8.9L Cummins to find the truth.
When a customer sent us this engine for a complete overhaul, we knew we had our work cut out for us. Follow along as we uncover the true state of this motor, from the cylinder head to the bottom end. Is it worth rebuilding, or is it a total loss? Find out in Part 1 of this project.

We’ve finished the plumbing and the wiring is in place. Watch the tense moment as we attempt the first startup. It’s not just about turning the key; it’s about testing the Haltech system and managing the cooling loop under pressure.

Sometimes the most complex builds have the most stubborn secrets. We’re deep into troubleshooting, checking ignition timing, and diagnosing backfiring issues to get this masterpiece running perfectly for its owner. See how we get to the bottom of it.

Join us as we start the high-stakes journey of prepping a custom V12 engine for a major reveal. With time running short and dyno availability delayed, see how we tackle the cooling systems and fuel line challenges on the shop floor.

Modern vehicles often come with "non-serviceable" parts that dealerships are trained to replace entirely. But at the shop, we love a challenge. Watch us break down this four-wheel-drive front differential to find a better, smarter way to solve a persistent leak without replacing the whole unit.

Sometimes a dealer's quote doesn't tell the whole story. We had a Sprinter owner come in after being told their vehicle needed a massive, expensive overhaul for what looked like a standard seal issue. See how we dig into the real problem to save the customer from unnecessary costs.

When the official repair manual says "replace it," you have to get creative. We show you the importance of measuring rotational torque and surface prep when performing a custom seal replacement. See how these small details lead to a perfectly dry, long-lasting repair.

We've committed to a full engine drop to perform a deep cleaning on these intake valves. It's a massive job, but seeing the transformation from 'clogged' to 'factory clean' is what it's all about. Honesty, thoroughness, and quality craftsmanship in every step.
