## ⚙️ Key Features

-   Documented in D8A1-A MP and TAD1342GE turbocharger installations
-   Cut profile aligns with the assigned flange and flow passages
-   Material is selected for heat, oil and exhaust-system exposure
-   Provides controlled compression without intruding into the flow path
-   Mating faces must be clean, flat and free from old gasket material
-   Single-use replacement is recommended whenever the joint is opened

## 🔌 Function

Seals the specified turbocharger or manifold joint against oil, air or exhaust leakage.

## ⚠️ Common Signs of Failure

-   Oil, boost air or exhaust gas leaks from the joint
-   Soot or oil staining appears around the flange
-   The gasket is burnt, split or eroded
-   Fastener loosening damages the sealing surface
-   Replacement is required whenever the joint is dismantled

## 🛠️ Service Notes

-   Always fit a new gasket, and take the old one off completely without scoring the joint faces — a plastic scraper and a residue-free solvent on aluminium, never an abrasive disc or a steel blade
-   Check both faces for flatness, corrosion pitting and pulled threads before assembly; a gasket cannot bridge a distorted or damaged joint face
-   Fit dry unless the procedure for your engine specifically calls for sealant — sealant on a gasket designed to run dry acts as a lubricant and lets the gasket creep out under clamping load
-   Locate the gasket on its dowels or bolts and check every port, passage and bolt hole lines up before anything is tightened
-   Draw the fasteners down in stages, evenly and from the centre outwards, to the figure in the workshop manual for your engine
-   Handle the gasket flat and unfolded — a crease or a nicked edge becomes a leak path
