Todd, Will, and Myer sit down to answer the question their own viewers keep asking: what actually kills a diesel engine. This isn't a highlight reel of blown up race trucks. It's a real conversation about the boring stuff that ends up costing you the most, and by the end you'll understand exactly why some trucks hit 400,000 miles and others don't make it past 100,000.

The guys start with air filtration, breaking down why a high flow filter built for the racetrack can be the wrong call for a truck that spends its life on dirt roads, and how a warped air box lid quietly sands down cylinder walls one mile at a time. From there they get into oil change intervals, why diesel oil has to fight abrasive soot, and why stretching that interval too far on a Cummins or any diesel truck build is gambling with the bottom end.

Fuel system maintenance gets serious attention too. Todd and Myer walk through algae contamination, injector failures on common rail systems, and why a cheap tune from Facebook Marketplace can melt a piston faster than almost anything else on this list. They break down EGT damage, ring wear, and valve seat problems, then go platform by platform. You'll hear about killer dowel pin issues on 12 valve Cummins trucks, VP44 fuel pressure sensitivity, the notorious CP4 pump problems on 6.7 Power Stroke trucks, head gasket failures on Duramax engines, and why the fifth gen Cummins hydraulic roller cam setup has turned into one of the more frustrating design decisions in recent diesel history.

Whether you're running a 5.9 Cummins, a 6.7 Cummins, a Power Stroke, or a Duramax, this episode gives you a real look at what wears these engines out and what you can actually do about it before it becomes an expensive lesson.

If you're a diesel guy who wrenches on your own truck, this is the kind of episode worth taking notes on.

Tuning is one of the most asked topics in the diesel world, so this episode of the Power Driven Podcast breaks down diesel tuning 101 straight from guys who actually tune their own trucks. Todd, Will, and Myer walk through what it really takes to start tuning a Dodge Cummins, whether it is a daily driver or a dedicated race truck.

They start with picking the right tuning platform, comparing EFI Live and HP Tuners for older and newer trucks, and explain how that software reads the ECM and unlocks the tuning tables hiding inside the factory computer. From there the conversation moves into fuel quantity, timing splits, and how injection pressure differs between a 12 valve pump truck and a modern common rail Cummins, and why that difference changes how aggressively you can safely run your tables.

The guys also get into the factory five position tune switch found on 06 and newer Dodge Cummins trucks, how racers use it to flip between tunes right from the cab, and how other diesel platforms like Ford handle the same idea through the cruise control buttons.
There is a long section on turbo spool, boost limited fueling, and reading an AFR gauge to hit the right air fuel ratio for a fast, clean spool without drowning the truck in smoke. That leads into a story about chasing spool on a Cummins sled pull truck that turned into one of the better lessons in this episode, plus why a properly tuned diesel will always beat someone trying to manage boost and fuel with their foot.

Whether you daily drive a Dodge Cummins or you are building out a diesel performance race truck, this episode gives you a real starting point for tuning your own truck instead of guessing at it and hoping for the best.

We took total strangers for rides down the racetrack in our diesel drag trucks, and it might be the most fun thing we've ever done at an event. This episode is a stroll down memory lane on the Power Driven Podcast, covering our trip to Montana for an NHRDA event and the first time each of us felt real horsepower behind the wheel.

Todd, Will, and Myer break down how the spectator ride along program came together, from a six year old getting the full harness experience to grown adults walking away shaking after a pass in the junker. We also cover what it takes to run those rides safely, watching trans temps and checking for leaks between passes.

Then we get into the technical side of the weekend. Myer talks through setting a new record for the fastest Dodge 48RE four speed transmission in a truck, running a 4.82 at 155 miles per hour in the eighth mile, and the tuning fix that got him there. There is a breakdown of why guys are moving from the 48RE to turbo 400 transmissions for pro street and eighth mile racing, and why the converter clutch dragging at the line is the real Achilles heel of the Dodge trans.

We also talk diesel truck racing classes, from mild 770 index trucks up to 590 Pro Street, and why a stock looking Cummins powered truck sitting in the parking lot could probably run mid elevens if the owner just gave it a shot.

We had a blast being part of this NHRDA event and hope to see more tracks doing spectator ride alongs. Come say hi in the pits if you catch us at the next NHRDA race in Ennis, Texas this September.

Blown head gaskets are one of the most common headaches diesel guys run into once they start chasing real power, and this episode breaks down exactly why they happen and how to actually fix it for good.

Todd, Will, and Myer get into it after a viral clip of a 6.7 Cummins shooting fire straight out the front of cylinder number one, and use it as the jumping off point for a full breakdown of head gasket failure.

The guys tackle the biggest myth in the diesel world first, that high drive pressure is what blows head gaskets. It is not. High cylinder pressure from advanced timing is the real culprit, and they explain why a tighter turbo setup that makes drive pressure is just a sign of an engine that is going to make power down low, which is where the real cylinder pressure spike happens.

From there the conversation moves into sealing solutions, starting with fire ring gaskets and split firing, which the guys call the ultimate ceiling technique for a high performance diesel build. They compare that to Top Fuel dragster hoops and C ring style seals, and explain why a fire ring is still the go to for iron block Cummins applications running big power, whether it is a 12 valve, a 24 valve, or a VP44 setup.

There is a deep dive into crush specs, retorque procedure, and the difference between how MLS gaskets and older factory gaskets handle a little bit of leakage, along with the common mistakes guys make when resurfacing a head at home with the wrong tools.

The guys also walk through real world troubleshooting, covering coolant leaks after a firing job, how much crush is too much, and what brands like Hazel and Industrial Injection are doing differently with their gasket specs.

If you are building a diesel truck for serious horsepower and want to avoid blowing a head gasket, or you are already dealing with one and trying to figure out why, this episode gives you the real explanation instead of the Facebook forum version.

Todd, Will, and Myer are back for round two on camshafts, picking up right where they left off and going even deeper into diesel cam theory. If you got something out of the last episode, this one takes it further with real numbers, real data, and some genuinely nerdy breakdowns that most Dodge Cummins guys never get access to.

This episode is built around volumetric efficiency and how race engines actually push past 100 percent. The crew explains scavenging, low pressure zones, and how intake air speed changes everything about when you should close that intake valve. They break down piston speed and rod angle, why 70 degrees after top dead center is the sweet spot for airflow, and why valve lift speed is limited by lifter size, which is a big reason Cummins runs such a massive lifter compared to the gas world.

From there Will pulls out actual cam data measured off real factory camshafts using a cam doctor tool, comparing intake and exhaust duration and valve timing across every generation of Cummins, first gen, 12 valve, VP44, and common rail. The differences in exhaust valve opening timing alone explain a lot about why certain Cummins generations start easier, burn cleaner, or make power differently. They also dig into intake and exhaust centerline angles and why lifting the valve higher instead of just chasing bigger duration numbers is often free horsepower with no downside.

The back half covers valve springs, coil bind, and why some aftermarket cams cause problems with stock components, plus a preview of a project cam being custom built for an upcoming race truck this September, designed specifically around a narrow RPM window instead of chasing bigger numbers across the board.

If part one gave you the foundation, this episode is where it gets real. Whether you are running a first gen, a 12 valve Dodge Cummins, a VP44, or a common rail, this breakdown gives you a real foundation on how factory and aftermarket camshafts are actually engineered.
