A little hoousekeeping: this should not be in "projects" which is for complete bike projects. "SOHC4" if the better place. It will likely be moved soon.
If your oil is appearing in fins between the cam cover gasket and the head gasket, it is likely coming from two places. THe rubber pucks under the cam towers, or the threaded holes which are open to the atmosphere and through which the holddown stud/bolts for the cam towers are threaded.
If its the pucks, well there you go. New pucks, layers of sealer.
THose threaded holes are the b--stards. Has your head been apart, have those holes been stripped and repaired, helicoil?
We just had a big thread on this lately.
