Revitalising Your Engine: A Deep Dive

Precision Engine Rebuilding and Cylinder Head Services

In the world of automotive maintenance and performance enhancement, the engine is undeniably the heart of any vehicle. Ensuring its optimal health and efficiency is paramount, whether you're a daily commuter seeking reliability or a performance enthusiast chasing speed. R.A.D. Auto Machine stands at the forefront of this critical field, offering a comprehensive suite of engine rebuilding and cylinder head services designed to breathe new life into your vehicle's powerplant. With a commitment to exact specifications and utilizing only the finest components, our state-of-the-art facility and expert technicians are dedicated to delivering unparalleled results.

What is Engine Rebuilding?

Engine rebuilding, often referred to as engine reconditioning or engine overhaul, is a meticulous process that involves disassembling an engine, cleaning, inspecting, and repairing or replacing worn or damaged parts. The goal is to restore the engine to its original factory specifications, or even to enhance its performance beyond those original parameters. This process can significantly extend the lifespan of an engine, improve fuel efficiency, and restore lost power and performance. It’s a cost-effective alternative to purchasing a new engine, especially for classic cars or vehicles where a full replacement would be prohibitively expensive.

R.A.D. Auto Machine's Engine Rebuilding Prowess

At R.A.D. Auto Machine, we pride ourselves on our state-of-the-art engine rebuilding capabilities. Our facility is equipped with cutting-edge machinery and staffed by highly skilled technicians who possess a deep understanding of internal combustion engines. We don't just rebuild engines; we craft them to exacting standards, often holding race tolerances to ensure superior performance and durability. Our process begins with a thorough inspection and diagnosis, followed by precision machining and the careful selection of only the best components. Whether your engine requires a standard rebuild to restore its original vitality or a performance-oriented upgrade, we have the expertise and technology to meet your needs.

Unrivalled Machining Capabilities

The cornerstone of our superior engine rebuilding lies in our advanced machining capabilities. We employ the Rottler F65A CNC Machining Center, a testament to our commitment to precision. This sophisticated piece of equipment allows us to perform critical operations such as:

• Blueprint Block Machining: Ensuring the block is perfectly squared and aligned from the main line and camshaft centerline.
• Deck Squaring: Guaranteeing a flat and true surface for head gasket sealing.
• Lifter Bore Truing: Maintaining precise alignment for camshaft lifters.
• Bore Spacing Corrections: Rectifying any inaccuracies in cylinder spacing.
• Line Boring: Restoring the integrity of bearing bores for crankshaft and camshafts.
• Block End Truing: Ensuring the front and rear seals are perfectly seated.
• Stroker Motor Clearances: Precisely machining for increased crankshaft throw.
• Main and Cam Line Corrections: Addressing any wear or misalignment in critical bearing journals.

Specialised Sleeve Installations

For specific engine platforms, including the popular LS1, Honda, and Nissan blocks, we offer specialised Darton Sleeve Installations. Sleeving is a process where the original cylinder liners are replaced with new, stronger ones, often necessary due to wear, damage, or to accommodate larger bore sizes for performance applications. Our precise installation ensures optimal sealing and durability.

Precision Cylinder Honing

The finish of the cylinder walls is crucial for proper piston ring seal and oil control. Our Rottler HP6A computerized Cylinder Hone is an exceptional tool that allows us to achieve exact cross-hatch angles and the required RA (Roughness Average) surface finishes specified by ring manufacturers. This precision in honing ensures optimal ring seating, reduces oil consumption, and contributes to increased power and efficiency, holding cylindricity to an incredible .0001 - .0002 inches.

Comprehensive In-House Services

R.A.D. Auto Machine offers a wide array of in-house services to cover every aspect of engine rebuilding:

Cylinder Head Services: The Key to Performance

The cylinder head plays a vital role in an engine's performance, controlling the intake of air-fuel mixture and the exhaust of burnt gases. Our cylinder head services are designed to maximise this efficiency:

• 3-5 Angle Valve Jobs: We perform multi-angle valve seat grinding to improve airflow, sealing, and valve cooling. This precision work ensures optimal combustion.
• Porting and Polishing: Our technicians meticulously port and polish intake and exhaust ports to smooth airflow, reduce turbulence, and increase the volume of air and fuel entering the combustion chamber.
• Flow Testing: Utilising our Super Flow SF660 flow bench, we measure and analyse airflow characteristics of the cylinder head, allowing us to optimise porting and valve jobs for maximum performance. This provides quantifiable data on the improvements made.

Dyno Testing and Tuning: The Ultimate Verification

To ensure our rebuilt engines perform at their absolute best, we conduct rigorous testing and break-in procedures. All of our performance engines are dyno tested and broken in on our state-of-the-art, fully computerized Engine Dynamometer. This allows us to:

• Verify Performance: Accurately measure horsepower and torque output under controlled conditions.
• Identify Issues: Detect any potential problems or anomalies before the engine is returned to the customer.
• Break-in Properly: Ensure the engine is run-in according to best practices, seating piston rings and ensuring all components work harmoniously.
• Dyno Tuning: For performance builds, we offer dyno tuning services to optimise fuel and ignition maps for maximum power and drivability.

We also have a Chassis Dyno and Super Flow flow bench capabilities, providing a comprehensive testing environment for all your engine needs.

Frequently Asked Questions

Q1: How long does an engine rebuild typically take?

A1: The timeframe for an engine rebuild can vary significantly depending on the complexity of the engine, the extent of the damage, and the availability of parts. Generally, a standard rebuild can take anywhere from two to six weeks. Performance builds or engines with extensive damage may take longer.

Q2: What is the difference between a rebuild and a remanufactured engine?

A2: A rebuilt engine is restored to its original specifications by disassembling, cleaning, inspecting, and replacing worn parts. A remanufactured engine typically undergoes a more rigorous process, often including upgrades and meeting or exceeding OEM standards, and usually comes with a more extensive warranty.

Q3: Will a rebuilt engine perform as well as a new one?

A3: When performed by a reputable facility like R.A.D. Auto Machine, a rebuilt engine can perform as well as, and sometimes even better than, a new engine, especially if performance enhancements are incorporated during the rebuild process. Our precision machining and quality component selection are key to achieving this.

Q4: What kind of warranty do you offer on your engine rebuilds?

A4: We offer a comprehensive warranty on our engine rebuilds, details of which can be discussed with our service advisors. Our commitment to quality means we stand behind our work.

Q5: How do I know if my engine needs rebuilding?

A5: Signs that your engine may need rebuilding include excessive smoke from the exhaust, significant loss of power, unusual noises (knocking or tapping), excessive oil consumption, or a drop in oil pressure. If you notice any of these symptoms, it's advisable to have your engine inspected by a qualified mechanic.
