Torque Diesel Service — Customer Case Studies
Twenty-three years of grease under fingernails. Turbos rebuilt, injectors calibrated, top-ends overhauled. Every truck that left this bay ran harder than the day it rolled off the line.
Intake manifold cracked at the EGR coolant passage — undetectable without a pressure test most shops skip. Third cylinder was washing down from condensate, not fuel. Took us 40 minutes to find what two others missed in three days.
Cracked EGR passage — the real culprit, not injectors
I'd already dropped $1,200 at two other places on parts that didn't fix anything. Brought it to Torque on a Tuesday afternoon. By Wednesday morning, Marcus had it on the lift, pressure-tested the intake, and called me with the actual diagnosis. Not a guess — an answer. The repair took one day. Truck's been clean ever since, 14,000 miles later.

VGT actuator seizing under boost — common on high-mileage 6.7s running max GVWR loads. We sourced an OEM actuator, bench-calibrated it, and had the truck back under load by 11 PM the same night.

I run hotshot. Every hour the truck isn't moving, I'm bleeding money and losing a customer. Called Torque at 2 PM on a Friday with a turbo surging under load. The guy on the phone — I think it was the owner — started troubleshooting with me before I even brought it in. When I pulled in at 3:30, they already had the part on order.
Truck was done at 11:04 PM. I know the exact time because I watched the bay doors open. Made my Phoenix delivery with four hours to spare. That's not a mechanic. That's a partner.

Contaminated diesel from a single fuel stop in Amarillo — injector tips eroding, rail pressure dropping across all four. We coordinated simultaneous teardowns across two bays, sourced injector sets from three suppliers to avoid back-order delays, and restored all four trucks in under 96 hours.
Dual-bay simultaneous teardown — Day 1
All four units cleared for road — 96 hours later
We had four Peterbilts fail injectors inside of one week — traced back to a contaminated fuel stop in Amarillo. The kind of scenario that can bankrupt a small fleet operation. I called Torque at 6 AM on a Saturday. They had a plan before I finished explaining the situation.
They ran two bays simultaneously, sourced parts from three different suppliers to cut lead time, and gave me a truck-by-truck status update every six hours. We lost zero freight commitments. I've been a fleet account with them for 18 months since. Won't go anywhere else.

No guessing. No parts-cannon approach. Bring it in, we diagnose it right, we fix it once. Owner-operators, fleet accounts, ranchers — same standard for everyone.
