Assemble engine.

There is air in the VANOS system once it is opened.

In the first few seconds after startup this can result in a clearly discernible "rattling noise".

This rattling noise does "not" indicate incorrect assembly.

The rattling noise will disappear as soon as the oil pressure has built up and the system has vented.

Carry out venting procedure with diagnosis tester.

Perform VANOS test.
