Used 6.5L Detroit Diesel for Sale — VIN-Verified.
Powerstroke, Duramax & Cummins — VIN-verified, tested diesels for Houston trucks, shipped right the first time. 0% restocking, ever.
Used & remanufactured 6.5L Detroit Diesel — VIN-verified, tested, and shipped nationwide from our Pasadena, TX facility. Fits Chevy/GMC trucks, vans & Hummer H1 (1992-2002).
The 6.5L Detroit Diesel came in turbo and non-turbo forms across a wide range of GM applications, so we confirm the exact variant and injection setup your vehicle needs. Known weak points we inspect include the PMD/injection-pump driver and cracked blocks. These are older mechanical/electronic engines with no DPF — we test and are upfront about condition, long-block or complete. Ultra Auto Parts TX is Houston's drivetrain specialist for used and remanufactured diesel engines, serving Pasadena, Deer Park, Baytown, La Porte, Channelview and the wider Gulf Coast truck market from our shop at 5041 Spencer Hwy, Ste 101, Pasadena, TX 77505. In a region built on work trucks, fleets and towing, we focus on the three diesel platforms Texans actually run — Ford Power Stroke, GM Duramax and Dodge/Ram Cummins — and match every long block or complete engine to your exact VIN before it ships. Unlike a general salvage yard, we treat diesels as core drivetrain, not random inventory. Every used diesel engine is VIN-verified against your truck's year, cab and emissions configuration, then inspected and tested before we quote a firm price. We speak English and Spanish, respond within 10 minutes during business hours, and back every diesel with a real warranty — so Houston owner-operators and shops buy with confidence.
Known issues we check on the 6.5L Detroit Diesel
The 1992-2002 6.5L came in turbo and non-turbo variants, so we first confirm which your truck, van, or Hummer H1 needs. We check the block for the cracking these engines are notorious for, and we verify the PMD injection-pump driver and pump condition, since PMD failure is the classic 6.5 no-start problem. With no DPF to worry about, our focus is the block, pump, and driver. Every 6.5L is VIN-matched and drivetrain-tested in Pasadena before we quote.
Used vs. remanufactured 6.5L Detroit Diesel — which to buy
A tested used 6.5L can serve you well when the block and injection pump check out, and ours are inspected for cracks and PMD-related issues first. Remanufactured is the safer bet given how prone these blocks are to cracking, and the longer warranty protects your investment. We carry both and help you weigh cost against reliability. Send your VIN or vehicle details and we will tell you honestly which makes sense for your 6.5L application.
Why buy a quality used diesel engines?
A diesel is the most expensive component in the truck, and a proper machine-shop overhaul often runs $8,000–$15,000+ once you add gaskets, injectors, machine work and labor. A quality tested used engine or a reman built to OEM spec gets you back on the road faster, at a fraction of that cost, with a warranty covering the assembly — not a shop's one-off labor guarantee. For a work truck losing money every day it's down, verified used or reman is usually the smarter math.
Common signs you need a replacement
We know these platforms cold: 6.0L Power Stroke head-gasket and stretched-head-bolt failures, EGR and oil-cooler issues; 6.4L Power Stroke cracked pistons; LB7 Duramax injector failures and later LLY overheating; Cummins 5.9L (12v/24v) VP44 and lift-pump issues, 6.7L DPF/EGR and injector wear; and high-mileage blowby on all three. We inspect for exactly these before quoting.
