Precision Engine Machining for Maximum Results

Our engine reconditioning process incorporates advanced machining techniques to restore your engine to factory specifications—or better. Here’s a closer look at the machining steps involved:

• Chemical Hot Wash: Your engine is thoroughly cleaned to remove contaminants.
• CNC Block Surfacing: We resurface the block using our Comec CNC machine to achieve a flawless finish.
• CNC Boring: The cylinders are precision-bored to size for consistent clearances.
• Torque Plate Honing: Our Sunnen honing machine ensures the cylinders are honed perfectly. This process, verified with a profilometer, guarantees precision for your engine’s application.

We also install brand-new pistons, rings, and bearings (for rods, cam and mains).

Run-In and Dyno Tuning for Peak Performance

Every engine rebuild undergoes a complete run-in process on our Mainline Prohub Dyno. During this procedure:

• GM-approved run-in oil is used to ensure a smooth break-in period.
• The engine is then run on the dyno to optimize performance across the entire RPM range.
• After the run-in, we replace the oil with premium synthetic oil.
• A custom dyno tune maximizes power and torque across the RPM range, tailored to your specific engine setup.

This comprehensive process ensures your fresh engine performs at its best from the start.

Avoid Catastrophic Valve Seat Drops

For 6L and 6.2L LS engines, there is a significant risk of valve seat drops after the engine has surpassed 150,000 km. This issue, often caused by overheating, can result in catastrophic block damage. Unfortunately, predicting when or if this will occur is impossible.To mitigate this risk, we recommend replacing your old heads with CNC Ported used heads that have new intake valve seats.  These high-quality components are reasonably priced and provide a reliable solution to this common problem.

Some engines require sleeving

This is because their bores are worn too much. They cannot be bored oversize. The factory cylinders may not be centered due to core shift. As a result, the block cannot be rebored. We install special sleeves which make the cylinders better than from factory. We use Melling usually.  Many LS3 and LSA require sleeving. 

Why Rebuild Instead of Replacing with a Crate Engine?

Many LS engine owners consider purchasing a crate engine as a quick fix. However, an engine rebuild  with engine reconditioning is often the smarter, more cost-effective choice. Here’s why:

1. Customized Performance: Unlike mass-produced crate engines, our rebuilds are tailored to your vehicle’s needs.
2. Superior Components: We use high-quality parts, including camshafts, pistons, and bearings, to ensure durability and reliability.
3. Cost Efficiency: Rebuilding your current engine can save you money. This option is often cheaper than buying a brand-new crate engine. You can achieve similar performance without the high cost. You get more for your money, and the result is better.
4. Enhanced Durability: Our sleeved block option delivers a stronger engine than new from GM. This is especially accurate with LS3 and LSA due to their core shift.

Selecting an Oztrack LS engine rebuild can help you save money. You will also enjoy a high-quality motor built to your exact specifications.

Manta Exhaust Integration for your LS Engine Build

To complement your engine rebuild, we also offer Manta Exhaust installations. As Platinum Dealers for Manta Exhaust, which owns DPE Exhaust, we provide competitive rates and professional installation services. Integrating a high-performance exhaust system with your LS engine rebuild further enhances your vehicle’s power and sound. We have VF Commodore Exhaust, VE Commodore Exhaust, HSV Exhaust, and VT-VZ Exhaust, which all perform very well.
