## 🔧 Product Description

Earlier valve cover 20412587 requires gasket 20412588. The applicable serial break differs by engine family; verify the complete engine product and serial.

## ⚙️ Key Features

-   Metal gasket designed specifically for valve cover 20725337
-   Maintains oil sealing around the rocker and valve mechanism
-   Reusable only where permitted by the workshop inspection criteria; renewal is recommended during service
-   Serial-dependent relative to earlier valve cover 20412587 and gasket 20412588
-   Used across D5/D7 and related 5- and 7-litre TD/TAD engine families
-   Engine type: Deutz 1012/1013-derived four- and six-cylinder turbocharged diesel

## 🔌 Function

Seals the valve cover to the cylinder head, retaining engine oil and preventing contamination from entering the rocker and valve mechanism.

## ⚠️ Common Signs of Failure

-   Engine-oil leakage around the valve-cover perimeter
-   Oil collecting on the cylinder head, intake or exhaust side
-   Gasket distortion, corrosion, fretting or loss of sealing preload
-   Oil mist and dirt accumulation around the cover joint
-   Persistent leakage caused by pairing the gasket with the wrong valve-cover version

## 🛠️ Service Notes

-   Fit a new gasket every time the joint is disturbed — a gasket takes a permanent set once it has been torqued and will not seal reliably a second time
-   Scrape both faces back to clean bare metal, keeping the blade at a shallow angle so it lifts the old material without gouging the surface, and use a plastic scraper on aluminium castings
-   Check the faces for flatness, cracks and corrosion pitting, and make sure no old gasket, carbon or hardened sealant is left in the corners or around the bolt holes
-   Fit the gasket dry unless the workshop manual for your engine calls for a sealant, and then only the type it specifies — surplus sealant squeezes out into oil, coolant and fuel passages
-   Draw the fasteners down progressively in the sequence and to the torque given in the manual for your engine, and recheck after the first heat cycle where the manual asks for it
