Knowing how to use an engine oil analysis report is one of the cheapest and most accurate ways to catch turbocharger wear before it turns into a grenaded center section and a four-figure repair bill. A $25 oil sample can tell you what’s happening inside your turbo, bearings, and bushings long before you hear a

Understanding the relationship between EGR System and Turbocharger Health is one of the most overlooked skills in diesel maintenance, yet it separates mechanics who fix symptoms from those who fix root causes. When an exhaust gas recirculation system goes bad, it rarely fails alone. It takes the turbocharger down with it, often slowly, often expensively,

Knowing how to install and read a boost gauge on a diesel truck is one of the most valuable diagnostic skills an owner-operator or fleet mechanic can have. A boost gauge tells you in real time what your turbocharger is doing under load, and that single reading can catch a failing turbo, a cracked intercooler

Knowing How to Replace a Turbocharger Inlet Pipe and Bellows is one of those skills that separates a mechanic who fixes the root cause from one who just chases boost leaks all week. The inlet pipe and its rubber bellows sit between the air filter housing (or intercooler outlet on some setups) and the turbo

Knowing how to replace intercooler boots and pipes on a diesel truck is one of the most valuable skills an owner-operator or fleet tech can have, because a single split boot can rob you of boost, torque, and fuel economy overnight. Charge air piping lives in a brutal environment: constant pressure cycling, engine heat, road

Knowing How to Replace a VGT Actuator is one of the most valuable skills a diesel mechanic can have, because a failed actuator will drop a truck into limp mode, kill fuel economy, and throw codes that mimic a dozen other problems. The good news is that on most engines the actuator is a bolt-on

Knowing how to remove a turbocharger on a Duramax is one of the most valuable skills you can have when working on the 6.6L GM diesel, because the LBZ, LMM, and LML variants all use variable geometry turbos that eventually need service, an actuator swap, or full replacement. The good news is that GM engineered

Knowing How to Remove a Turbocharger on a 6.7L Cummins is one of the most valuable skills a Ram 2500 or 3500 owner can have, whether you’re replacing a failed unit, swapping in a rebuilt turbo, or servicing the variable geometry components underneath. The 6.7L Cummins uses a Holset variable-geometry turbo that sits low on

Knowing How to Remove a Turbocharger on a Ford 6.0L Powerstroke is one of the most valuable skills a diesel tech or owner-operator can have, because this engine’s Garrett GT3782VA is notorious for sticking vanes, oil leaks, and mount-up headaches that put trucks in the shop for days. At PT Turbo, we’ve been rebuilding turbochargers
