"From the illustration below you can see the small brass filter. This can clog up over time, especially on a car that does not have its engine oil changed regularly. Once clogged up it will restrict or prevent the oil flow, and this can cause serious problems. The obvious cure is to remove this 'brass filter'.

While you are doing this, AND WITH THE CYLINDER HEAD REMOVED, you should enlarge the oil passageway of the brass restrictor within this oil gallery. This brass restrictor has a passageway with a diameter of 0.5mm. This should be drilled out to 0.8mm AND NO MORE!!! Make sure you then pass an air pressure hose through this oil gallery to clear out any metal shavings.
