Remanufactured Engine Buyer’s Guide

Remanufactured engines are a great price/performance option – but only if you are sure you’re choosing a high-quality and reputable remanufacturer. Reman engines are renewed from top to bottom. This means that they are stripped, cleaned, machined and re-assembled. New parts are used where needed. The quality of remanufactured engines varies greatly depending on the processes used to renew them – and our method is among the best. Learn about each step below:

Disassembly And Cleaning

Every engine remanufacturing process begins with a complete disassembly. Iron components are hot tanked, a process in which heat and industrial chemicals are applied to the parts to remove dirt, rust, and carbon buildup.

Aluminum parts are thermally cleaned in a separate process so that they do not become damaged or brittle from excessive temperatures. The intake and exhaust manifold surfaces are also thoroughly cleaned and buffed to ensure that no rust, dirt, or grease enters the engine. Depending on the state of the engine, a second cleaning process may be completed.

Inspection Procedure 

Ferrous parts have a large iron component, which makes them magnetic. We use Magnaflux testing to detect cracks or fissures in these engine parts. It is a completely non-destructive and non-invasive inspection method that allows us to detect abnormalities that aren’t visible to the naked eye.

Then, all non-ferrous parts are thoroughly inspected. If any issues are detected, the affected parts are repaired or replaced.

Machining And New Parts

Once the block has been cleaned and inspected, it is time to machine the surfaces to ensure a perfect fit. We use a Computer Numerical Control (CNC) machining process that allows for tight tolerances and a perfectly flat mating surface. Each remanufactured engine gets a full set of new components, including:

• Bearings
• Pistons
• Rings
• Lifters
• Oil Pump
• Gaskets
• Viton valve seals
• Freeze and galley plugs
• Timing chain/belt, including tensioner
• Water pump – on timing chain/belt-driven pumps 

Sim Testing

Once the engine has been completely reassembled, it is time for a comprehensive test. Our testing procedure ensures that all the new components fit perfectly and have bedded in without issue.

We use a simulation testing procedure(SIM) that will highlight any issues before the engine is fitted to a vehicle or sold.

The SIM testing procedure includes spinning the engine at 750 rpm on a custom-designed rig. This tests the compression levels and pressurizes the oil. The engine lifters are also pumped up, which reduces any tapping noises when starting up for the first time.

On Variable Valve Timing (VVT) engines, the cam actuators are engaged to ensure correct timing. The cooling system is pressurized, and the complete engine is checked for leaks.

High Quality Remanufactured Engines From Powertrain Products

Not every remanufactured engine is the same. Powertrain Products doesn’t just remanufacture an engine; we make it better by rectifying any known factory faults. We use new components and conduct comprehensive testing on every rebuilt engine. That is why we can offer an industry-beating warranty. Reasons to choose a PPI remanufactured or rebuilt engine include: 

• High-Quality Parts – We Use New Parts To Rebuild Our Engines
• Warranty Protection Up To Seven Years, One Million Miles
• Rigorous Testing Ensures Optimal Performance That Meets Or Exceeds OEM Specs 

Powertrain Products stocks a full range of engines for domestic and imported models. We offer a 3-year standard warranty on all our engines, transmissions, differentials, and transfer cases. 

That standard warranty can be upgraded to 5 or 7 years or 1 million miles, whichever comes first. For the ultimate protection, you can add our no-fault Pure Care™ Warranty to your purchase. We’re also the nation’s leading supplier of differentials and transfer cases. Call us at 888-842-0023 or contact us online.
