## ⚠️ Common Signs of Failure

-   Engine is being rebuilt
-   Multiple oil or coolant leaks are present
-   Timing cover or sump has been removed
-   Existing gaskets are hardened or damaged
-   Cylinder-head gasket is being selected separately

## 🛠️ Service Notes

-   Check the kit contents against the joints you are actually opening before you start, and lay the parts out so nothing is left in the bag
-   Renew every gasket in the kit as a set; a used gasket has already taken its crush and will not seal a second time
-   Clean the mating faces properly without gouging them — a plastic or hardwood scraper and a solvent are safer than a steel blade, especially on aluminium
-   Fit gaskets dry unless the workshop manual for your engine specifies a sealant, and then use only the sealant it names
-   Tighten the joint evenly in the sequence and to the figures given in the manual for your engine, and re-check after the first heat cycle where the manual calls for it
