3.2.1 Important information
●
When working on the cylinder head and valve train, always use engine oil to lubricate sliding parts
when assembling. Never assembly dry parts into the valve train.
●
The camshaft is lubricated by engine oil supplied via an oil passage in the cylinder head. Make sure
this passage is clean and open when you reassemble the head.
●
When measuring parts to determine wear, wash the parts with solvent and dry them in order to get
accurate measurements.
●
When disassembling the valve components, keep them in order, and reinstall them in the reverse
order.
