    Cummins Engine Building Tips Part 2: Bearings, Break-In, and First Fire

    Part two of the engine building series picks up right where things left off, covering everything from bearing installation all the way through first fire and ring break-in. If you are building a Cummins or planning to, this is the episode you do not skip. Todd, Will, and Myer break down the full Morley bearing lineup, covering P, H, and V bearings and which one belongs in which build. Coated bearings, bearing installation technique, and why cleanliness between the bearing and saddle matters more than most guys realize all get covered in detail. Plastic gauge gets a thorough breakdown too, including an honest story about what happens when you misread a dial bore gauge. Wrist pin clip orientation, rod direction by platform, crank galley cleaning, and which way rods go in a 12 valve versus a 24 valve versus a VP44 are all walked through in real shop language. So are crank gear welding, cam retainers, piston protrusion targets, firing head gasket installation, head stud torque sequence, and valve lash strategy. The break-in section is worth the entire runtime on its own. Proper cam break-in, why you do it without coolant in the block, how to track oil temp with an infrared gun, and why ring break-in requires load are all covered. The crew explains why babying a fresh built diesel causes glazing and oil consumption issues, and breaks down break-in oil, first oil change timing, and cutting open the filter to check for debris.

    How to Build a Cummins Engine the Right Way (Part 1)

    If you have ever cracked open an engine block and wondered whether you are missing something the shop guys never talk about, this episode is for you. Todd, Will, and Myer break down the real hands-on engine building process, step by step, using their Myers UCC build as the backdrop for a conversation that covers everything from the stuff you check before you turn a wrench to the stuff that will bite you if you skip it. The episode kicks off with oil galley plug inspection, what the guys call the oil rail, oil rifle, or oil passage depending on who is talking, and why making sure every one of those plugs is seated before assembly is a non-negotiable. They get into cleaning procedures using an engine bore brush kit to pull out machining particles and metal flakes from the cylinder bores and oil passages before anything goes back together. Bearing clearances get a solid breakdown here. The guys walk through main bearings and rod bearings on a Cummins engine, explain why the oil holes in the bearings do not line up the way you might expect, and talk through what proper clearance looks like for street builds versus high RPM race applications. They also hit a detail that trips up a lot of first-time builders: rod caps are matched to their specific rod during the machining process, and swapping caps between rods will cost you roundness and likely an engine. Cylinder wall prep takes up a good chunk of the conversation too. The guys reference using the Total Seal ring break-in compound to verify cleanliness, where green means the wall is ready and brown means you are not done yet. From there the discussion moves into piston ring gap, how they set the second ring at or slightly larger than the top ring, ring orientation during installation, and their experience running Total Seal gapless second rings at higher horsepower levels where piston land strength starts to become a real concern. The back half of the episode covers assembly lube, specifically the Joe Gibbs Driven line and other black assembly greases the guys have had good results with, where to apply it and where not to, and the proper way to lube a camshaft, lifters, and cam lobes before the engine goes together. The cylinder head side of the build runs long and gets pushed to next week, so consider this Part 1 of a two-part deep look at what it actually takes to build a diesel engine the right way.

    The Truth About Diesel Pistons: Cast vs Forged, Bowl Design, and What to Run in Your Build

    Pistons are one of those parts everybody installs but not everybody actually understands. Todd, Will, and Myer break down piston design from top to bottom, and if you have ever wondered why there are so many options or which one belongs in your build, this is the episode you need. They start with piston bowl design and why it matters more than most guys think. Narrow bowl versus wide bowl, reentrant versus non-reentrant, and how each design affects the way fuel and air mix inside a diesel cylinder. Because diesels fire fuel directly into that bowl at the very end of the compression stroke, bowl geometry has a direct impact on combustion quality, smoke, and power output in a way gasoline engines never have to deal with. Swirl numbers get covered too, and why that circular mixing motion plays a bigger role in emissions and haze than it does in outright peak power. The conversation moves through piston options platform by platform. Common rail, 24 valve, VP44, and 12 valve all get their own breakdown. The guys talk about why they almost always steer people toward a narrow bowl for over-the-road use, but also when a wide bowl makes sense, like sled pulling and nitrous-limited classes where you are chasing every last horsepower. Cast versus forged is a big chunk of this episode and the guys do not sugarcoat it. Forged pistons are stronger and handle RPM abuse better, but the increased wall clearance required, the wear characteristics, and the oil ring differences make them a poor choice for anything that sees regular street miles. They even mention their factory 6.7 cast pistons surviving a truck that averages 2200 horsepower down the track, and what that says about how capable a properly built cast piston really is. The 12 valve guys get their section too. Stock pistons, the early first gen wider bowl swap, and why the shop has largely moved away from recommending low compression pistons now that six seven blocks are the go-to platform for high-output Cummins builds. Piston coatings and cylinder honing round out the episode. The guys cover their coating experiments on Myer's race truck, what coatings can and cannot protect against, and why proper piston wall clearance is still the thing that determines whether any of it survives.

    Why Your Diesel Tows Like Garbage (And How To Fix It)

    Every diesel guy has been there. The truck feels great empty, pulls hard, and you love it right up until you hook a trailer to it. Todd, Will, and Myer dig into exactly why that happens and what you can actually do about it. The conversation starts with a real story about building a 12 valve for power without thinking about what it would have to do. Big pump, big single turbo, five speed, and a trailer to tow. The result was exactly what you would expect from a setup built for the strip and not the highway. It towed, but it was miserable, and that experience sets up everything else in the episode. From there the guys get into tuning strategy for trucks that need to work. Pedal mapping and throttle input are a bigger deal than most people think, especially when your transmission is mechanically activated and does not know your engine is making twice the power it was designed around. If your transmission thinks you are at light throttle while your engine is at full pull, you are going to have a bad time. Getting the tune and the transmission working together is step one. Turbo selection comes up as one of the biggest places guys go wrong when building a tow truck. Oversized turbos that are great for making peak power numbers are often terrible for towing because they surge, they come on hard, and they kill drive manners under load. Compressor wheel clearances also factor into efficiency and reliability in ways most people do not think about. The right turbo for towing is not the biggest one you can bolt on. Fuel system choices matter too. Massive injectors and multi-pump setups introduce complexity and reliability concerns that become a real problem when you are stranded on the side of the road a long way from home. For a dedicated tow truck, simple and reliable beats flashy every time. Carrying spare parts because you know your setup is likely to break is not a strategy. Tires are another thing that can quietly kill your tow truck. Load ratings, tire size, and how they affect your effective gear ratio all play into how your truck behaves under a load. Going up in tire size without accounting for everything downstream can smoke a transmission and make towing miserable regardless of what else you have done to the truck. The core takeaway is something the guys come back to repeatedly. You have to decide what your truck actually is before you build it. A dedicated tow truck and a street truck that occasionally tows are two completely different builds. You can have a modified truck that tows great, but the parts and strategy have to match the application. If you are building a diesel and towing is part of the plan, this episode is worth your time.

    Everything You Need to Know About Cummins Engine Blocks

    Not all Cummins blocks are built the same, and if you are pushing serious power, the one under your hood matters more than most people think. Todd, Will, and Myer break down the full spectrum of Cummins engine blocks in this episode, from the various 12-valve generations to the 5.9 common rail and the 6.7, and explain exactly why the differences matter when the power numbers start climbing. The 6.7 gets a lot of attention here, and for good reason. The conversation covers what makes it structurally superior to earlier platforms: a thicker deck, a larger bore, longer wrist pins, and pistons that have held up to 3,000 horsepower in competition builds without giving up. The guys talk through how modern tuning lets builders get even more out of what is essentially a factory race motor sitting in everyday trucks, and why the 6.7 has earned its reputation as the current king of Cummins diesel performance. The 12-valve conversation goes deeper than most. There are meaningful differences between block variations that matter at high power levels, and the guys cover what to look for. Power Driven offers a 14-millimeter main stud upgrade across their block lineup, including as a standard feature on their 12-valve block, because the math on clamping force versus a stock bolt simply does not leave room for argument. One topic worth paying attention to is the roller lifter issue on newer 6.7 trucks. The guys call it out as a real problem already hitting a significant number of engines, potentially on the scale of what the VP44 pump failure was for the 24-valve crowd. If you own a 2019-and-up Ram with a 6.7, this part of the conversation is worth your time. There is also a breakdown of why dropping a 12-valve head onto a 6.7 block causes combustion problems. The 12-valve injector enters the cylinder at an angle, so the piston bowl is offset toward that injector. A centered bowl piston paired with an off-center injector creates combustion characteristics nobody wants. It is a simple geometry explanation that answers a question the comment section apparently asks regularly. The guys wrap up with some real-world context, including Todd running 10-second passes in his tow truck and a story about winning the fastest pass at an airport drag race against mustangs and a supercharged F-150 on a 6.90 slip. The point being that the power these engines support on the street right now is genuinely historic.

    We Went to NHRDA Arizona And Won $20,000

    The crew is back from Arizona and this one is worth every minute. Todd, Will, and Myer all showed up to the NHRDA Arizona event with trucks ready to race, and nothing went according to plan in the best possible way. If you have ever thought about getting into diesel motorsports, this episode is going to push you over the edge. The NHRDA Arizona event was a well run show under new ownership that delivered on the details, from clear signage to efficient staging lanes to bonus qualifying rounds when time allowed. The crowd was big, the energy was right, and even a PDD shop employee who had never raced before got talked into running Willard the tow truck and came back asking where he could buy one. That is what these events do to people. Todd lined up in the NHRDA Blue Collar class with Vin D against a stacked field of modern power and a $20,000 winner take all purse on the line. The 12 valve Cummins pump gun had something to say about how that ended. Will brought Uncle Rico to the 590 class, qualified strong, and had a legitimate shot at a trophy run before the motor had other ideas on Saturday morning. Myer's Scrat build finally made it to the track after months of fabrication and a last minute Thursday night dyno session that gave everyone just enough confidence to load up and go. The truck made an impression in a hurry. The episode closes with the burnout contest, the Junker, a neutral drop on compound boost, a wall, an exploding fan clutch, and a water methanol tank that had the track crew convinced there was a fuel spill on their hands. If you want to race and you have been sitting on the fence, get a truck ready and show up to an NHRDA event. You do not need an expensive build and nobody is going to give you a hard time for being new. More events are on the calendar including Indiana in June and Montana in August.
