Stock & Modified Truck Engines Built for Power, Reliability & Performance
Walls Rod Custom is your premier Canadian diesel tuning specialist
At WallsRod and Custom, we specialize in professional truck engine repair in Winnipeg, offering complete stock engine replacements, precision rebuilds, and fully engineered modified performance engines.
Whether your engine has failed, lost compression, or is burning oil, or you’re ready to increase towing power safely — we provide solutions built for Manitoba’s climate and real-world workloads.
Your truck isn’t just transportation. It’s your livelihood.
Stock Engine Repair & Replacement
Not every engine problem means full replacement. We start with accurate diagnostics to determine whether your truck needs:
- Full engine rebuild
- Remanufactured engine installation
- Head gasket repair
- Turbo replacement
- Injector service
- Bottom-end repair
- Oil system diagnosis
- Complete engine replacement
Many customers come to us after receiving extremely high dealership quotes. Diesel engine replacements in Canada can exceed $25,000–$30,000+. We help you explore cost-effective rebuild and reman options that restore reliability without unnecessary upselling. If your truck is part of a work fleet, ask about our Fleet Maintenance Services to prevent major engine failures before they happen.
Modified & Performance Engines
If you’re looking to increase horsepower, towing torque, or build a race-ready truck, we don’t just add power — we build engines that can handle it.
Our performance engine services include:
- Stroker diesel engine builds
- Ported cylinder heads
- Forged rotating assemblies
- Custom pistons
- Performance camshafts
- Cooling and oiling upgrades
Power without proper support shortens engine life. That’s why we integrate upgrades across your entire powertrain.
To maximize results, many customers combine engine builds with:
- Custom Tuning for optimized fuel and timing maps
- Dyno Tuning to verify safe air/fuel ratios and torque output
- Fuel Systems Service to ensure injectors and pumps can support added power
- Exhaust System Services to improve flow and reduce backpressure
- Transmissions & Drivelines upgrades to handle increased torque
Every build is tailored to your goals — whether it’s heavy towing, daily driving, or competition.
Built for Canadian Conditions
Cold starts. Short trips. Heavy loads. Winter idling.
Modern diesel engines face additional stress in Manitoba’s climate. We address common concerns such as:
- DPF & regeneration issues
- Cold-weather oil flow
- Turbo wear
- Fuel system strain
- Emissions-related sensor failures
If your truck sits high or runs oversized tires, pairing engine upgrades with Suspension & Lift Kits ensures proper driveline angles and performance balance. Looking to personalize your build? We also offer Accessories Services to complete your setup.

Truck Engine Repair: F.A.Q.
How do I know if I need engine repair or full replacement?
Low compression, metal in oil, severe knocking, or catastrophic failure may require replacement. However, many issues like injector failure, turbo problems, or head gasket leaks can be repaired without replacing the entire engine. We diagnose before recommending major work.
How much does truck engine repair cost in Winnipeg?
Costs vary depending on engine type (gas vs diesel) and damage severity. We provide clear estimates and options — including rebuilds and remanufactured engines — so you can choose what fits your budget.
Is modifying my engine safe?
Yes — when done properly. Problems occur when tuning is added without strengthening internal components or supporting systems. Our approach balances engine internals, tuning, fueling, exhaust flow, and driveline strength.
Will performance tuning damage my engine?
Improper tuning can. That’s why we recommend professional Custom Tuning and verified Dyno Tuning to ensure safe power gains and proper air/fuel ratios.
Do modified engines require more maintenance?
Generally yes. Higher output engines experience more stress and require regular inspections, fluid checks, and monitoring. We can set up a maintenance plan to protect your build.
My diesel truck keeps having regen or DPF problems. What can I do?
Frequent short trips and cold weather can cause incomplete regen cycles. We diagnose the root cause and recommend maintenance or system corrections to prevent repeat issues.
Can you upgrade my transmission to handle more power?
Yes. Increased torque often requires supporting upgrades through our Transmissions & Drivelines services to prevent premature failure.
Can you improve towing performance without a full engine build?
Absolutely. Many customers start with Custom Tuning, Fuel Systems Service, or Exhaust System Services to safely improve torque and efficiency.
