A cylinder head gasket for sealing the cylinder head to the engine block on 3TNV70 three‐cylinder diesel engines used in mini excavators, compact loaders, and power equipment. This precision-cut gasket maintains combustion pressure while keeping oil and coolant passages sealed under high heat and load, helping the engine run efficiently and reliably. Made from robust metallic layers with reinforced sealing around each cylinder, it is built for the duty cycles typical of small construction plant and generators. Manufactured to OE-style dimensions for a secure fit, it supports clean installation and dependable operation. Supplied as a single head gasket, reference 080 684, it is suitable for repairs, rebuilds, or preventative maintenance on engines based on the 3TNV70 platform.

Key Features:
– Direct-fit replacement for engines based on the 3TNV70 platform, with OE-style port and bore alignment
– Durable multi-layer metallic construction designed to resist heat, pressure, and vibration
– Reinforced sealing around combustion chambers to maintain compression and reduce blow-by
– Accurate coolant and oil passage sealing to help prevent cross-leaks and overheating
– Stable sealing beads and edge treatments to maintain clamping load over time
– Fits without modification when head and block are within service limits, supporting straightforward installation
– Supports correct compression ratio by matching original thickness specification
– Corrosion-resistant finish to withstand diesel engine environments
– Suitable for use with standard head bolts or studs as specified by the engine manufacturer
– Ideal for scheduled overhauls or reactive repairs where reliability is essential

Typical Applications:
Used in small construction and industrial equipment powered by 3TNV70 engines, including mini excavators, compact loaders, site dumpers, generator sets, and pump units. Suitable for workshop engine rebuilds and on-site repairs where a dependable head seal is required to restore performance and prevent fluid leakage.
