Cylinder head assembly [Toyota 4Runner N120]

Before starting assembly, it is necessary to make sure that the cylinder head is clean, regardless of whether this part was repaired in a car service or not.



1. If the cylinder head was repaired in a car service, then measure the height of the spring in the installed state.

2. Install all valve mechanism parts in reverse order.



3. When pressing on the valve stem seals, remember that the inlet and outlet valve stem seals are different.



4. Before assembly, grease the crackers to temporarily hold them in place.
