Trusted Diesel Repair and Performance Services near Newark, OH
Looking for specialized diesel repair near Newark, OH? Unlimited Diesel Performance in Bremen is a diesel-focused repair facility serving Powerstroke, Cummins, and Duramax truck owners throughout Licking County and Central Ohio. From difficult starting problems and fuel injection failures to complex electrical diagnostics and engine repairs, our team combines hands-on diesel experience with advanced diagnostic equipment, in-house fuel injector remanufacturing, and machining capabilities. We focus on finding the underlying problem, explaining the repair options clearly, and helping you make informed decisions about your truck.
What Newark Diesel Truck Owners Actually Need From a Shop
Diesel trucks are not just transportation for most of the people who bring them to us. They are pulling rigs, work tools, and passion projects. When something goes wrong, the last thing you want is a technician who is Googling the fault code while the clock runs on your bill.
The reality is that most general repair facilities in the Newark area are set up to handle gas-engine service efficiently. Diesel platforms, especially the HEUI injectors in a 7.3 Powerstroke, the variable geometry turbos on a Duramax, or the fuel system vulnerabilities in a 6.7 Cummins, require a completely different level of investment in tooling, training, and hands-on experience.
Unlimited Diesel Performance has been building that experience since 2004. Every technician, every piece of equipment, and every workflow in the shop is pointed at one thing: diesel.
The Diagnostic Difference Newark Drivers Are Looking For
We hear it constantly from new customers: they have already been to two or three shops, the truck is still not right, and in some cases the same part has been replaced twice. That is a diagnostics problem, not a parts problem.
How We Approach Diesel Diagnostics
Every vehicle goes through the Unlimited Diesel Performance Complete Vehicle Health Inspection before any repair recommendation is made. Our Snap-On Zeus scanner with a four-channel lab scope captures real data across fuel pressure, injection control pressure, contribution balance, and electrical readings. We take the time to find the root cause because a repair that misses the actual failure is money wasted.
Wiring and Electrical Diagnosis
Electrical faults on diesel platforms, from valve cover harnesses on a 7.3 Powerstroke to sensor circuits on modern Cummins trucks, can show up as almost any drivability complaint. Our team takes on complex wiring diagnosis that most shops in the region decline. If your truck has been passed around without a real answer, that is exactly the kind of case we are built for.
Diesel Platforms and Failures We Handle for Newark Truck Owners
- 7.3 Powerstroke Injector Failures: We remanufacture these completely in-house, including teardown, ultrasonic cleaning, new internal components, clearance reset, and flow-bench verification. Not a clean-and-reseal operation.
- 6.7 Powerstroke CP4 Injection Pump Failure: When the CP4’s internal lifter fails, metal debris contaminates injectors, rails, and lines in a single event. We perform the S&S Diesel DCR Pump conversion to eliminate the failure at the source.
- 6.0 Powerstroke Head Gasket and EGR Cooler Failures: We address both together. Fixing one without the other is how trucks come back a few months later.
- 6.7 Powerstroke Main Bearing Failures: Our in-house machining department handles this work start to finish with no outside machine shop involved.
- LB7 Injector Failures: The 2001-2004 LB7 is known for injector failures that can lead to fuel dilution in the engine oil if left unaddressed. We replace these with genuine Bosch or S&S Diesel injectors matched to your power goals.
- LML CP4 to CP3 Conversion: The 2011-2016 LML Duramax CP4 is prone to failure. We convert these trucks to a more dependable CP3 system.
- Stuck Turbo Vanes: Soot buildup locks up variable geometry vanes and kills power. We find the root cause and restore proper function.
- VP44 Injection Pump Failures (1998-2002): We address the injection pump and the lift pump together. Lift pump failure is frequently the actual cause, and ignoring it guarantees a repeat.
- Valve Seat Failures (2003-2004 5.9L Cummins): Dropped valve seats can cause catastrophic engine damage and may damage the injector nozzle when a seat falls into the combustion chamber. We have a proven repair solution for this failure.
- CP4 to CP3 Pump Conversions (2019-2020): These Cummins trucks are strong candidates for a full CP3 conversion before the pump fails and contaminates the system.
- VGT and EGR Cooler Failures (2007 and Up): We diagnose the root cause before ordering parts. Replacing the cooler without addressing the underlying issue is a temporary fix.
- 2019 and Up Lifter and Camshaft Failures: Newer 6.7 Cummins trucks have documented roller lifter failures that can cause significant engine damage. We diagnose and repair these in-house.
