Hi!from the date I hope you have cured the problem.
If you are still having problems I suggest that you remove the cylinder head oil gallery plugs(these are in-line with your spark plugs ) with a hex spanner ( they can be very tight ) and renew the o-rings as they have hardened/cracked and are leaking onto your plugs. I know---took me a while to find the leak too. found them while doing a head gasket change.
