Cylinder Head and Reassembely

The Cylinder head covers the cylinder block. It contains parts such as the rocker arms, valve springs, valves and the Camshaft.
It works together with the cylinder block e.g. the pistons work in time with the valves in order to power the engine. 


Theory Background:
What I'm doing is reassembling the cylinder head completely.
How to reassemble the cylinder head:
1st:
You make sure that the cylinder head is clean and there is nothing clogging any passage ways or gaps.
2nd:
After that, you have to put all the valve springs back into the head. 
 


To do this you need to use a spring compressor to push the springs down on the valve in order to put the valve keepers in.
 
This is a diagram of how the valves should be assembled.
3rd:
After the valves have been put back in, you then put the Camshaft back into the cylinder head.
 
4th:
Once the Camshaft is back in the cylinder head, the rocker arms need to go back on.
 
The rocker arms work together with the Camshaft, e.g. when the cam lobes push on one end of the rocker arm, the other end opens the valve.


The cylinder head should look like this when completed:
