Many issues can result from reusing o-rings some of which could be, low oil
pressure and oil leakage. Always use new o-rings and make sure they are in the
appropriate locations.
1. Place the head gasket over the dowels.
2. Note that the letter F or R is cast into the top of the cylinder head to ensure proper
installation. Carefully set the cylinder head over the two dowels in the cylinder
head mating surface. Be careful not to drag the gasket surface across the dowels.
CAUTIO !
Thoroughly clean and lubricate the threads of the cylinder head bolts prior to
installation. Dirt, grime, and dry interfaces can cause friction, resulting in false
torque values.
3. Lightly coat the threads and bottom flange of the head bolts with clean light
engine oil.
