Customer: replied 1 year ago.

does the oil gallery have a removable orifice at block

Expert:  Eric replied 1 year ago.
HI,

To be honest, I am not sure on that. Let me check the Mazda field manual for that.
Customer: replied 1 year ago.

did you check manual on orifice

Expert:  Greg replied 1 year ago.

This engine does not have an oil orifice as you say but has a OCV system for the VVT.

No need to worry about this on this engine when doing the cylinder head gasket .

just remove the OCV and make sure its clean and free of sludge ,

I have nothing on this part, and to be honest never seen it on any of the engines i've done head gaskets on,

except the old Toyota engines, and this was in the top part of the engine block and not in the cylinder head .
