A brief overview of JASPER's gas engine remanufacturing process. | Jasper Engines & Transmissions

Here at Jasper Engines & Transmissions, precision and quality are key, and the Associates of Head Machining in POD 10 are essential to our remanufactured engines! The processes in Head Machining include a thorough parts inspection. Valves springs are measured for pressure on an in-house developed tester. At the overhead cam station, cam caps are installed, honed, and measured for accuracy. Valve seats are cut at different angles to ensure proper valve seating, optimize engine performance, and en

This "Spot the problem" is for the technicians and machine guys that know what to look for when tearing down an engine. This L92/LS3 engine had 350k miles on it before we decided to tear it down. It was running excellent but didn't have the greatest oil pressure. There's your hint. #reels #video #meta #engine #teardown #fypシ #fyp #machine #auto #automotive #mechanic #technician #builder | Jasper Motorsport

At JASPER®, we don’t take shortcuts—especially when it comes to remanufacturing cylinder heads. In this video, watch as our skilled technicians use a fusion welding process to restore cracked cast iron heads to OE-level performance. By heating the head, welding with precision, and slowly cooling it, we restore the structural integrity that cheaper, aftermarket heads just can’t match. Why do we do it? Because quality matters. Many of our customers trust the durability of the original OE head over

One hundred percent of the VVTs built at Jasper Engines must pass our Hydraulic VVT test stand. This state of the art machine has custom fixtures built for each application to mimic oiling systems in the vehicle, including the OE solenoid and proper oil viscosity at operating temperature. VVTs are tested at minimum operating oil pressure checking flow characteristics (for internal clearances), angle set-point control (to ensure the VVT will move to desired angle within a pre-set time), and a loc

Here at Jasper Engines and Transmissions, we’ve invested in a state-of-the-art Mazak CNC machining unit—specifically designed to perfect the overhead cam bores in our cylinder heads. This video features a 5.0L Coyote head. How it works: • Heads are mounted on a rotating tombstone holding up to 4 at a time. • A Renishaw probe identifies each head and selects the correct machining process. • A high-precision cutting bar, cooled with ultra-filtered oil (up to 10 microns!), ensures clean cuts and a
