Precision Boring for All Engine Types: We specialize in precision cylinder boring for both automotive and large diesel engines, ensuring each cylinder is perfectly resized to manufacturer specifications or custom requirements. Our advanced boring and honing equipment restores cylinders to their original glory, ensuring a perfect fit for piston rings and reducing oil consumption.
Sleeve Installation and Boring: For cylinders that are excessively worn or damaged, we offer sleeve installation services. This involves inserting new cylinder sleeves into the engine block, followed by precise boring and honing to restore the cylinders to their original dimensions or desired specifications. This process not only saves engines that would otherwise be deemed irreparable but also can be used to modify engines for increased displacement or performance tuning
Advanced Honing Techniques: Our honing process utilizes the latest in technology to achieve the ideal surface finish and cross-hatch pattern, essential for effective oil retention and piston ring sealing.
An engine head is more than just a component; it’s the key to your engine's power and efficiency. Our services ensure that this vital part is in top condition, enhancing your vehicle's performance and prolonging its life
At TurnCraft, our engine head services are a cornerstone of precision and performance. The engine head, pivotal in controlling airflow and combustion in your vehicle's engine, requires expert attention to maintain peak efficiency. Our specialized services cater to a range of needs, from standard refurbishments to performance upgrades
Thorough Inspection and Diagnosis
Utilizing advanced diagnostic tools, we conduct a comprehensive examination of the engine head, identifying any issues like cracks, warping, or valve wear.
Technical Detail: We use precision measurement tools such as micrometers and straightedges to assess flatness and valve seat wear to tolerances within 0.001 inches.
Valve Job and Resurfacing
We perform a detailed valve job which includes cleaning, inspection, grinding or replacing valves, and reconditioning or replacing valve seats.
Technical Detail: Valves are ground to achieve a perfect seal, and valve seats are cut using a 3-angle cut method for improved flow and efficiency.
For resurfacing, we use a surface grinder or milling machine, ensuring the head's surface is flat to within 0.002 inches, crucial for optimal gasket sealing and engine performance.
Porting and Polishing (For Performance Enhancement)
This process involves reshaping the intake and exhaust ports to improve airflow. We carefully remove material to enlarge and smooth the ports, enhancing engine "breathing" and efficiency.
Technical Detail: Porting is done with precision to maintain wall thickness and avoid port mismatch, while polishing is performed to a smooth finish, reducing air turbulence and resistance.
