Honest Diesel Repair for Sequim Drivers Who Are Tired of the Runaround
You’ve got a job lined up outside Sequim, the trailer’s loaded, and the check engine light comes on halfway down US-101. Your stomach drops. Not because you can’t drive it — because you already know the last shop “fixed” this exact code three days before your truck died on the highway. You’ve been down this road. Literally.
Sequim sits in the rain shadow on the north edge of the Olympic Peninsula, and the drive from your place to a shop that actually knows diesels feels longer every time something breaks. Flying Wrench Services is out at 31516 Commercial Ave NE in Kingston — a straight shot east on 101 and then up toward the Kingston side of Kitsap County. It’s a real diesel shop, not a general garage that “works on diesels too” when they have to.
We know what it’s like to own a truck that IS your income. When a Powerstroke is down, the Peterson job gets pushed, the invoices stall, and you’re eating crow on the phone with your crew. Since 2002 we’ve been the shop working diesel owners trust to diagnose it right the first time — no guessing, no parts-cannon, no lectures about common rail systems you already understand better than the guy holding the scanner.
Why Sequim Diesel Owners Choose Flying Wrench Services
Straight Talk Without the Pressure Tactics
You don’t want to be sold a cabin air filter when you came in for a turbo. Here’s how we keep it honest:
- We diagnose before we quote — no throwing injectors at a fuel-delivery problem
- You get the actual code, what it means, and what it’ll cost — in plain language
- We call before we do work you didn’t approve, every single time
- If it’s a simple fix, we tell you it’s a simple fix
As the most reviewed local diesel repair shop in the area, our reputation is built on owners who came in skeptical and left knowing they weren’t played. That matters when your truck and your name are on the line.
Dealership-Level Diagnostics Without the Dealership Wait
You’d rather set the truck on fire than sit in a dealership waiting room for six hours. We get it. What you get with us instead:
- Factory-level diesel diagnostic equipment (J-Pro & TEXA) — not a $40 code reader
- Days, not weeks — we know downtime costs you jobs
- Working-man labor rates, not boutique pricing
- One shop for repairs, inspections, fleet work, and performance
As Heavy-Duty Diesel Specialists and Light Duty Diesel Specialists, we cover the full range — from your daily-driver Cummins to a self-loader or excavator. You call one shop and it’s handled.
Comprehensive Diesel Services for Sequim Drivers
Sequim Diagnostic and Repair Services

Climate-Ready Service for Olympic Peninsula Driving
Sequim’s cool, damp coastal air is easier on a diesel than desert heat — but the moisture and the winter cold bring their own problems. Hard starts on a frosty morning often come back to glow plug replacement or fuel-water separation. The damp accelerates corrosion on connectors and grounds, which is why diesel electrical repair is a bigger deal here than most owners expect.
Towing a gooseneck over the peninsula’s grades works your cooling system hard, so we keep a close eye on cooling system repair and the emissions components that struggle in stop-and-go peninsula traffic — from EGR valves to DPF cleaning. Staying ahead of these is far cheaper than getting stranded on 101.
Make-Specific and Specialty Service
You’ve got a Powerstroke, a Cummins, and a Kubota — and you want one shop for all of it. That’s exactly what we are. We specialize in:
- Powerstroke repair for your F-350 and the truck that pulls your livelihood
- Cummins repair for your daily-driver 2500
- Duramax repair and heavy equipment repair for excavators and loaders
- Performance upgrades — done right, by people who know what a tuner does to your emissions
Running more than one truck for your business? Our fleet services keep small contractor fleets on the road with scheduled maintenance and priority turnaround.
Serving Sequim and the Wider Olympic Peninsula
Sequim sits along US-101 in Clallam County, in the rain shadow between the Olympic Mountains and the Strait of Juan de Fuca. From our Kingston shop it’s a manageable run east across the peninsula, and we regularly serve diesel owners heading our way from all across the north Olympic corridor.
If you’re coming from farther out or through neighboring communities, we also cover Port Angeles to the west, Port Townsend to the east, and the broader Clallam County area. For many working owners, the drive is worth it to have a shop that actually gets diesels and gets you back to work fast.
