Several cylinder heads were installed with an additional injector shim underneath the injector.
If the injector shim is not installed or two injector shims are installed, a malfunction of the engine may occur (e.g. irregular engine running, exhaust fumes).

IMPORTANT: If the injector spacer shim is lost, the entire cylinder head has to be replaced!
