The Growing Shift Toward Non-Genuine Engine Parts and How It Affects UMZ-4216 Cylinder Heads
There has been ongoing discussion about non-original engine components, and it seems that counterfeit spare parts for several car brands are moving from rumor to reality. When selecting major parts and assemblies, it remains crucial to proceed with meticulous care. On a recent presentation, GAZ representatives on the factory channel compared the performance and practicality of a non-original cylinder head designed for the UMZ-4216 engine with the original unit supplied by the manufacturer, offering a practical look at real-world outcomes.
What matters here is the packaging of the head. The patented delivery kit includes gaskets and fasteners, allowing buyers to assemble the engine without a trip to the aftermarket shops. Yet a third-party cylinder head that arrives with a more basic setup can slash upfront costs. In this comparison, a third-party option could save around 30 thousand rubles, while a branded, complete kit runs about 35 thousand rubles.
During the evaluation, the third-party header was not deemed inferior to the original in terms of operational capabilities. The researchers described the procedure and shared the insights gleaned from the tests. First, both cylinder heads underwent precise dimensional measurements to verify accuracy. The results showed several discrepancies in dimensions claimed by the third-party manufacturer.
Subsequently, both heads were installed on the engine and run continuously for 400 hours, with half of that time at peak torque. The outcomes were telling. The UMZ-4216 head from the original supplier completed the test without failure and maintained consistent performance throughout. In contrast, the non-original head exhibited excessive wear in the intake bushings after just 200 hours, surpassing permissible limits multiple times. In other words, the service life of the non-original component would be substantially shorter.
