PARTSQUEEN Cylinder Head Cover Full Range European and Chinese Car Models

Cylinder head cover is a sealing plate located at the top of the engine that, together with the cylinder head, forms a sealed enclosure. It not only protects the camshaft and valve train—keeping out dust and preventing leaks—but also balances internal engine pressure via a built-in Positive Crankcase Ventilation (PCV) valve. Cylinder Head Cover Advantages – Manufacturing Process 1. The molds for these valve covers are developed based on original manufacturer (OEM) data and undergo multiple rounds of optimization, resulting in a fit with the cylinder head (or block) that is superior to standard OEM replacements. 2. Each unit is shaped for flatness using an authentic cylinder head; the flatness deviation between the valve cover and the cylinder head is less than 2mm. 3. Each unit undergoes bolt-hole alignment verification against an authentic cylinder head, with a positional deviation of less than 1mm. 4. The one-way valves and PCV (crankcase ventilation) valves in every unit undergo multiple airtightness tests involving both positive and negative pressure. A final comprehensive airtightness test is performed before packaging; only units showing no leakage are approved for shipment, thereby preventing oil or air leaks after installation. Cylinder Head Cover Advantages – Materials 1. All gaskets are made from the same ACM material used by the OEM. Additionally, every batch of gaskets undergoes high-temperature aging and compression set testing, with compression set results remaining below 20%. 2. All rubber components for the PCV valves utilize imported FVMQ material, offering exceptional temperature resistance (ranging from -50°C to 250°C) and superior resistance to temperature extremes and aging compared to standard rubber materials. 3. The Dacromet coating applied to the bolts utilizes the same imported materials and processes as the OEM parts. Here PARTSQUEEN only supply premium quality, and provide 24 months warranty, we always deserve your trust.
