Exhaust & Emissions System Repair

A healthy exhaust system keeps fumes out of the cabin, keeps the engine running efficiently and keeps things quiet. On modern diesels, the exhaust system is also a complex emissions system that needs to work correctly for the truck to run right.

Signs of exhaust problems

• Louder exhaust, or a ticking noise on cold start (manifold leak)
• Rattling from under the vehicle (loose heat shield or failed hanger)
• Exhaust smell inside the cab. Take this one seriously: carbon monoxide is dangerous
• Check engine light for catalytic converter or oxygen sensor codes
• Hanging or dragging pipes

What we do on gas vehicles

• Exhaust leak diagnosis and repair
• Exhaust manifold and manifold gasket repair, including broken studs
• Pipe, muffler and resonator replacement
• Hangers, clamps and heat shields
• Oxygen sensor and catalytic converter diagnosis and replacement

Diesel emissions systems

Late-model diesels use several systems to meet emissions rules, and each one can cause warning lights, power loss or reduced-speed modes when it acts up:

• EGR (exhaust gas recirculation) valves and coolers
• DPF (diesel particulate filter) and its pressure and temperature sensors, plus regeneration problems
• DEF / SCR systems: DEF pumps, heaters, injectors and quality sensors
• NOx sensors and exhaust gas temperature sensors
• Up-pipes and turbo-to-exhaust connections, including 6.4L Power Stroke up-pipe leaks

We diagnose these systems properly, repair the failed components and get your truck running right and compliant. Short trips and lots of idling are hard on DPFs; we can also talk about driving habits that help regeneration complete. More on diesel repair.
