TB48 Head Bolt Set - For Nissan Patrol Y61 GU

This head bolt set is an essential engine component used to secure the cylinder head to the engine block of your TB48 motor. These high-tensile bolts are responsible for applying the precise and even clamping force needed to create a perfect seal with the head gasket. For any 4x4 owner performing a top-end engine rebuild or replacing a blown head gasket, replacing the head bolts is not optional—it is a critical step. These bolts are a one-time-use, Torque-to-Yield (TTY) part, meaning they are designed to stretch permanently when torqued to specification, and cannot be safely reused.

The risk: What happens to the vehicle if this problem is ignored? Reusing old head bolts will inevitably lead to an incorrect and insufficient clamping force on the new head gasket. This will cause the gasket to fail prematurely, leading to a mix of coolant and oil, severe engine overheating, loss of compression, and potentially catastrophic damage such as a warped cylinder head or a cracked block.
