About this episode

A diesel shop owner recounts how an EPA raid upended his life—agents arrived with a federal warrant, seized diesel parts, and even tried to copy digital data. Years later, the case escalated into Clean Air Act conspiracy charges framed as a “blanket charge,” with uncertainty, monitoring, and no clear compliance guidance. The hosts connect the story to broader diesel legality shifts, explaining that “making it not criminal” doesn’t equal permission to “buy and install.”

Technical Too Afraid to Ask
Concept

emergency vehicles

"They're an emergency vehicle. [605.5s] They gotta clear the road so that everybody else can go."

An emergency vehicle is a vehicle that responds to urgent situations, like medical emergencies or fires. Because it has to get there fast, other traffic is expected to make room.

turbo

"We had different turbos, manifolds, [758.8s] all kinds of stuff on the show."

A turbocharger is a device that uses exhaust gases to spin and push more air into the engine. More air usually means more power, but it needs good sealing and cooling to work well.

delete

"Some of these jobs, let me point this out, like it might not even be, say, a deleted vehicle come in the shop for work on it. Even if we hadn't been the one to delete it, and we get a truck comes in and needs a turbocharger, and you change the turbo on it, you are now responsible for that delete."

Here, “delete” means someone removed or turned off parts that control a truck’s exhaust pollution. The discussion is about how a shop can still be held responsible if they work on a truck that already had those emissions parts removed.

rolling coal

"And I'd tell them that, you know, that pickup's rolling coal, absolutely."

“Rolling coal” means a diesel truck blows out a lot of thick black smoke when you accelerate. It’s often caused by changes to how the engine injects fuel, so it smokes more than normal.

Term

EPA emissions output

"whatever sort of emissions goal or emissions output they're trying to do"

Emissions output is how much pollution comes out of the exhaust when the truck is tested. If the numbers are low enough, it can pass emissions checks; if not, it fails.

Term

opacity tests

"We've got trucks that we sent to California that had carb testing done. I mean, they're passing opacity tests,"

Opacity tests check how smoky the exhaust is. They measure how much light the smoke blocks—more smoke usually means more soot, and passing means the truck is producing less visible pollution.

EGR filters

"I mean, there's so many parts, whether it's piston design or the EGR filters or DPF, high flow DPFs or tuning"

EGR is a system that sends some exhaust back into the engine to cut down on harmful emissions. The “EGR filters” are parts that catch soot in that exhaust stream so the system can keep working properly.

Term

DPF

"whether it's piston design or the EGR filters or DPF, high flow DPFs or tuning"

A DPF is a diesel exhaust filter that traps soot so it doesn’t go out into the air. Over time it has to clean itself (regenerate) or it can cause problems with the car.

Sign in to suggest edits or report issues
Term

tuning

"or the EGR filters or DPF, high flow DPFs or tuning and the capability they have with that"

“Tuning” typically means changing the computer settings in the engine. On diesels, that can change how the car burns fuel and how its emissions systems (like the DPF) behave.
