Every Rover Parts Depo engine begins with a core that’s completely disassembled and inspected. Each part is then meticulously cleaned, machined, and rebuilt according to OEM specifications — restoring the engine to factory-level performance and reliability.
Each component is stripped, cleaned, and examined using precision tools and professional testing methods:
Micrometers and gauge blocks are used to check tolerances.
Non-destructive testing (NDT) such as magnaflux and ultrasonic testing detects cracks or imperfections invisible to the eye.
Cylinder heads, crankshafts, rods, and blocks are all inspected and certified before reassembly.
This process ensures the foundation of every Rover Parts Depo engine is as solid as the day it left the factory — often better.
Our state-of-the-art machine shop is where each component is reconditioned to precise tolerances.
Cylinder blocks are resurfaced, bored, and honed to exact measurements.
Crankshafts are ground, polished, and balanced.
Cylinder heads are planed and pressure-tested to guarantee a perfect seal.
Valves, rods, pistons, and bearings are all restored or replaced to meet exact OEM specifications.
These steps are what make a Rover Parts Depo remanufactured engine truly in-house rebuilt — not just refurbished.
Some parts are always replaced to ensure reliability and performance:
Bearings, gaskets, seals, and O-rings
Timing chains, belts, tensioners, and guides
Oil pumps, pistons, and rings
Valves, springs, and lifters
Replacing these components guarantees consistent oil pressure, proper timing, and long-term engine health — matching or exceeding brand-new OEM performance.
Each rebuilt engine is reassembled by trained specialists using OEM torque specs and assembly procedures.
Every step is checked and double-checked. Before leaving our facility, the engine undergoes:
Compression and leak-down testing
Oil pressure and flow verification
Only engines that meet our exacting standards advance to dyno testing — the final proof of performance.
Cylinder compression test reading 140 PSI — strong pressure above 120 means the engine’s cylinders are sealing properly and delivering peak power.
Performance Verification | Precise Tuning:
Each engine is run through controlled engine cycles to confirm horsepower and torque outputs match factory specifications — ensuring your vehicle performs exactly as designed.
Component Break-In:
Engine testing properly breaks in new piston rings, bearings, and camshafts under carefully managed conditions — preventing premature wear and ensuring long service life.
Early Problem Detection:
Engine tests allow our technicians to detect potential issues (such as internal noise, oil pressure variations, or sensor malfunctions) before installation.
Comprehensive Quality Assurance:
During testing, we monitor vital metrics like:
Oil pressure and flow
Coolant and exhaust temperatures
Air-fuel ratios
Ignition timing and throttle response
When you buy from Rover Parts Depo, you’re not just getting a rebuilt motor — you’re getting a engine proven to deliver dependable performance.
Every Rover Parts Depo remanufactured engine comes with a standard 1-Year Warranty covering defects in materials and workmanship. For customers who want maximum protection, we also offer our RPD Promise 2-Year Engine Warranty — an extended coverage package that adds unlimited mileage, labor reimbursement, and an extended protection window.
Both warranties require proper installation at a licensed repair facility, maintenance documentation, and claim authorization from Rover Parts Depo.
