What is the torque specification for cylinder head bolts?
1 Answers
Cylinder head bolt torque specifications vary depending on the vehicle model. Here are the key functions of cylinder head bolts: 1. Isolation function: Separates engine oil from air. During engine operation, oil mist forms. The cooler inner surface of the valve cover collects this oil mist, allowing the oil to condense and flow back down into the oil pan. 2. Filler role: Serves as the engine oil filler port. This structure can be as simple as a hole where the oil filler cap is screwed in, or it may be a more complex oil filler tube. 3. Sealing function: Covers and seals the cylinder head, keeping oil inside while preventing contamination from dirt, moisture, and other external pollutants.
