Compression - Test
An engine that runs roughly can have a leak at the valves. An engine that runs roughly can also have valves that need an adjustment. Remove the head and inspect the valves and valve seats. This is necessary in order to find defects that would not normally cause a problem. Repairs of these problems are normally done when you are reconditioning the engine.
The cylinder heads consist of the following main components that can be removed:
- Valve seat inserts
- Valve guides
When any of these components are worn or when these components are damaged, these components can be removed. Refer to Disassembly and Assembly for the replacement of these components.
