head oil rail
There are 4 oil rail drain plugs - 2 on each head. 
When removing injectors for servicing or replacement, the oil rails should be drained prior to removing the injector. This will prevent the oil rail contents from draining into the cylinder and causing hydrolock and possible damage to the engine.

The cylinder will still require evacuation of any coolant and/or oil before cranking the engine after servicing the injectors. 

The Allen hex headed plugs should be removed but using a socketed Allen wrench on a short extension. Insert the Allen wrench into the head and give the extension a few taps with a hammer to assure that the wrench is fully seated in the plug and to help break the plug threads loose from the head.

    My old o-rings were rather dry and brittle. When I tried to remove them, one broke. There are four needed total.

    This item comes with all four o-rings.

    Smart to remove these plugs and allow the high pressure oil rails in the cylinder heads drain for 15 minutes before you pull out the injectors. Otherwise the oil in the rails will end up in the cylinders.
