When this Cummins rolled into the shop, it wasn't exactly subtle about its condition.

Oil was covering the engine, running down the frame rails, and making its way onto the tailgate. At that point, we already knew the engine had excessive blow-by.

But the real surprise came during teardown.

Normally, removing a piston from the cylinder takes some effort. This one? Let's just say it practically wanted to come out on its own.

Severe cylinder wear and worn piston rings had allowed so much combustion pressure to bypass the pistons that the crankcase was becoming pressurized, pushing oil out of every weak point it could find.

Blow-by isn't just an inconvenience or an oil leak. It's often a warning sign of significant internal engine wear that can lead to reduced performance, increased oil consumption, and eventually a complete loss of reliability.

The outside of this engine was telling a story. Once we got inside, it confirmed everything.

Sometimes the diagnosis starts before the first wrench is turned.

Proper maintenance is one of the most important factors in keeping your diesel truck reliable and avoiding costly repairs.

Routine maintenance includes engine oil changes, fuel filter replacement, transmission and driveline services, and servicing the emissions system. One area that is often overlooked is the DEF system. Allowing the DEF tank to run low enough to trigger speed limitations or a no-start condition can place additional stress on components such as the DEF pump and level sensor, potentially leading to expensive aftertreatment repairs.

Whether you perform your own maintenance or trust our team to handle it, staying ahead of scheduled service intervals is essential. Preventive maintenance is always more affordable than major repairs and helps keep your truck operating at its best when you need it most.

A little maintenance today can help prevent a big repair bill tomorrow.

The 68RFE transmission often gets a bad reputation for weak overdrive clutches but in reality, those clutches are usually just the symptom of a deeper issue.

In this failure, a snap ring came loose and caused excessive movement in the drum. That movement led to the overdrive clutch pack burning up. It didn’t stop there—the added play also allowed contact that damaged the 2–4 piston assembly.

This is exactly why, at Price Diesel Performance, we follow a strict set of upgrades as our minimum standard for every build. We don’t cut corners or ignore known failure points. Every transmission is built with durability in mind, so you can depend on it under heavy load, towing, or performance use.

If you’re ready to bring your 68RFE back to life—and build it the right way—give us a call to schedule your build at 904-903-0301
