At Apex Automotive in Gilbert, AZ, our engine rebuilding service to stock specifications restores your engine to factory-original performance and reliability. Led by David Sr. and David Jr., this service is built on decades of specialized engine experience, emphasizing precision, diagnostic-first workflows, and quality craftsmanship tailored for the rigors of desert driving.
An engine rebuild involves disassembling the entire engine, inspecting every component for wear or damage, and then replacing or refurbishing parts to meet exact OEM tolerances. This includes honing cylinders, resurfacing heads, replacing piston rings, bearings, gaskets, and seals, and reassembling the engine with strict adherence to torque specifications. The goal is to return your engine to “like-new” condition, ensuring smooth operation, proper compression, and efficient combustion.
Arizona’s intense heat and dusty environment accelerate engine wear by increasing operating temperatures and contaminant exposure. Engines, particularly GM 5.3L and 6.2L V8s with AFM/DOD systems, often experience lifter failures, carbon buildup in GDI engines, and oil consumption issues. Our stock rebuilds address these common failure modes by thoroughly cleaning components, using walnut blasting for carbon removal, and replacing wear-prone parts with OEM or equivalent quality replacements.
David Jr. uses a diagnostic-first process to pinpoint engine issues before rebuilding. This includes a comprehensive OBD-II scan, live data stream monitoring, and component-level testing to confirm the precise problem — avoiding unnecessary part replacements and costly guesswork. We then review findings with you to ensure transparency and build a tailored repair plan.
Our rebuilds are performed in collaboration with trusted machine shops like Gene’s Engine Service, known for precision machining and quality control. Every step from inspection to final assembly is done with care and technical expertise, including verification of torque specs and clearances.
This service is offered by appointment only, emphasizing dedicated attention and thoroughness over quick turnaround. If your engine is showing symptoms like rough running, loss of power, or increased exhaust smoke, trust Apex Automotive to rebuild it to stock specifications that restore reliability and performance for Arizona’s challenging driving conditions.
