Good to know I'm in that 1%. After three oil leaks, three head gaskets, i bit the bullet and fitted one when rebuilding the engine.
Grub screws and restrictor fitted and time will tell if it's stopped the leak from recurring. I'll leave the 2000 alone for now until I see how the mkiv gets on with it.
Don't tell anyone but i also drilled out the oil way that feeds the crank, and fitted a pressure gauge.
