Searching for a shop that truly understands the quirks and strengths of your 7.3 or 6.0L Powerstroke?
If you’re searching for Powerstroke 7.3 or 6.0 diesel repair in Central Ohio, you’re likely facing performance issues, injector problems, or ongoing concerns that other shops haven’t been able to solve. This blog is here to answer that question clearly: Unlimited Diesel Performance is the shop trusted by diesel truck owners across Central Ohio for expert diagnostics, emissions solutions, and injector services, especially on the Ford Powerstroke platforms.
In this post, we’ll break down the most common issues with 7.3L and 6.0L Powerstroke engines, explain why experience and equipment matter, and show you what sets Unlimited Diesel apart as the region’s leading diesel performance shop since 2004.
Powerstroke Diesel Repair Backed by Experience
Unlimited Diesel Performance was founded by enthusiasts who live and breathe the 7.3L Powerstroke platform. What started as a hobby turned into a full-time commitment to helping other Ford diesel owners get the most out of their trucks.
Today, our shop has grown to include a full diesel engine machine shop, an in-house fuel injector department with national and international reach, and a highly skilled drive-in service team that handles everything from complex diagnostics to emissions repairs.
We specialize in:
- 7.3L Powerstroke Injector Rebuilding: We’re one of the few shops in the country that rebuild and flow-test 7.3L injectors in-house. Our process delivers consistent performance, backed by hands-on experience and advanced testing tools.
- 6.0L Powerstroke Head Gasket and EGR Repairs: Known for head gasket and EGR failures, the 6.0L demands precision repairs. We use upgraded components and proven methods to restore reliability and prevent repeat issues.
- Diesel Engine Diagnostics: Whether it’s a no-start or power loss, we find the root cause with expert-level accuracy. Our experience means fewer guesses and faster, lasting solutions.
- Ford Factory-Level Scan Tool Diagnostics: Using Ford IDS and FDR tools, we access your truck’s systems just like the dealer would—enabling exact tests and faster diagnostics.
- Emissions and Drivability Issues: From check engine lights to poor throttle response, we address performance and emissions concerns with a full-system approach that gets your truck running right.
Common 7.3L Powerstroke Problems and Our Solutions
While the 7.3L is known for its durability, age and use introduce predictable wear patterns. Central Ohio diesel owners frequently bring their 7.3 trucks to us with:
Worn or Contaminated Injectors
This is one of the most common 7.3L issues we see. Worn-out plungers and barrels or debris contamination result in hard starts, rough idling, or poor performance. Unlike most repair shops, Unlimited Diesel Performance rebuilds 7.3L injectors in-house. Each injector is flow-tested to verify consistency and performance before being shipped or installed.
High-Pressure Oil System Failures
An aging HPOP (high-pressure oil pump) or related sensors and seals can cause long crank times or a no-start condition. We’re equipped to accurately diagnose and repair oil system issues using factory-level equipment.
Early 1999 Air Filter Issues
Some early models had faulty air filter clips that allowed unfiltered air to enter the engine, causing long-term wear. We always inspect intake systems during our Complete Health Inspection to catch these kinds of problems.
Intermittent Starting or Performance Concerns
Many trucks arrive from surrounding towns like Newark or Circleville with intermittent issues that have stumped other shops. Our Snap-On Zeus scanner and Ford IDS system allow us to trace these problems back to root causes.
The 6.0L Powerstroke: What You Need to Know
Though powerful, the 6.0L Powerstroke has developed a reputation for its complex issues. At Unlimited Diesel, we’ve built a track record of solving these problems the right way—without band-aids or guesswork.
Lifter and Camshaft Failures
Lifter collapse or rotation can destroy the camshaft. Our technicians know what warning signs to look for and what teardown steps are necessary to assess the full extent of damage.
Head Gasket and EGR Failures
Overheating, white smoke, and coolant loss are all signs of 6.0L head gasket or EGR cooler problems. We’ve completed countless repairs, installing upgraded components to prevent recurrence and ensure long-term reliability.
Turbo and Boost System Failures
Sticky turbo vanes are a common issue. Carbon deposits reduce responsiveness and overall performance. We disassemble, clean, and reassemble turbo systems to restore full boost and throttle control.
Injector Replacements
Unlike our rebuild program for the 7.3L, we do not rebuild 6.0L injectors. Instead, we install new injectors from Bosch or Alliant Power, ensuring the best combination of reliability and longevity.

Our Policy on Injector Replacements
Unlimited Diesel Performance is one of the few diesel repair facilities in Ohio with a dedicated in-house fuel injector rebuild program, but that applies exclusively to the 7.3L Powerstroke.
For all other engines, including:
- 6.0, 6.4, and 6.7 Powerstroke
- Cummins
- Duramax
We provide new injector replacements only. Depending on your truck and your power goals, we install trusted brands like Bosch, Alliant Power, S&S Diesel, and DDP (Dynomite Diesel Performance). For Cummins trucks especially, we’ll tailor injector selection to match your horsepower targets and usage, whether for towing, work, or performance.
Upgrading Powerstroke Fuel Systems: What to Know About DCR Pumps
There’s some confusion around CP3 conversions, so here’s a quick breakdown:
- Duramax and Cummins: These engines can be upgraded with a CP3 conversion, replacing the failure-prone CP4 with a more reliable and proven CP3 pump. It’s a popular upgrade for improved fuel system durability and long-term performance.
- 6.7L Powerstroke: While these also use a CP4 from the factory, the correct replacement is the DCR pump from S&S Diesel. It’s designed specifically for Powerstroke applications, offering enhanced reliability while staying emissions-compliant.
At Unlimited Diesel, we’ve performed both types of conversions and will help you decide the best path based on your engine platform and goals.
Diesel Diagnostics with the Right Tools
Diesel problems aren’t always obvious, and that’s where real diagnostic skill matters. Our customers from places like Zanesville, Chillicothe, and across Central Ohio choose Unlimited Diesel because we’re not a “guess and check” shop. We rely on precise data, advanced tooling, and platform-specific expertise to find the actual cause of your truck’s issues.
Our diagnostics process is backed by professional-grade equipment, including:
- Snap-On Zeus with 4-channel lab scope: Allows us to capture live waveforms and signals to pinpoint sensor and electrical faults.
- Ford IDS and FDR Scan Tools: Dealer-level diagnostics for Powerstroke platforms are critical for accurate testing and module communication.
- Remote Control Borescope: Helps us inspect internal engine components like cylinder walls, pistons, and valves without teardown.
- RMC VM5020 CNC Mill: Supports precision machining for engine components when repairs go beyond diagnostics.
- Flow Bench for Injector Testing: Verifies the consistency and performance of 7.3L injectors we rebuild in-house.
- Hot Tank Cleaning System: Deep-cleans parts to ensure proper sealing and performance during reassembly.
This investment in equipment lets us catch developing issues early, avoid misdiagnosis, and clearly explain our options. It’s part of what makes Unlimited Diesel the trusted choice for Powerstroke owners across the region.

Frequently Asked Questions About Powerstroke Diesel Repairs
What should I look for when choosing a diesel repair shop for my Powerstroke?
Look for a shop that specializes in Ford Powerstroke engines and uses factory-level diagnostic tools like Ford IDS. A good diesel shop should also offer transparency, documented inspections, and a warranty on parts and labor. Unlimited Diesel Performance checks all of these boxes and more.
Are rebuilt diesel injectors reliable for long-term use?
Yes, when rebuilt properly using OEM parts and flow-tested for consistency, rebuilt injectors—especially for 7.3L Powerstrokes—can offer performance and reliability comparable to new ones. Unlimited Diesel rebuilds 7.3L injectors in-house to maintain strict quality control.
Can emissions-related issues affect my Powerstroke’s performance?
Absolutely. Faulty EGR valves, DPF clogs, or sensor malfunctions can reduce fuel economy, throttle response, and even trigger limp mode. Addressing emissions systems with precise diagnostics ensures your truck runs clean and strong.
How often should I have a Complete Health Inspection done on my diesel truck?
At a minimum, once per year or before any major road trips or towing season. This inspection helps identify developing problems early, saving you time and costly repairs down the line.
Do I need dealer-only service to maintain my Powerstroke’s reliability?
Not at all. Independent shops like Unlimited Diesel Performance use dealer-level scan tools and have extensive platform-specific experience, often providing more personalized and responsive service than dealerships.
