Cylinder head plug weeping oil
This plug has been weeping oil for a while and I want to fix it. Can I just unscrew it and put some teflon on the threads and be done with it?

Edit
After not finding any pictures and getting the info from 2 or 3 other threads I decided to put this out there for future reference.
The factory O-ring is listed on the parts diagram as being 16.3mmX1.5mm. I went to the local hardware store and was surprised to find they had metric O-rings. I picked up a couple 16x1.5 and a couple 5/8x1/16 standard sized for a whopping 30 cents each. I ended up using the 5/8 O-ring because the 16mm just didn't seem like it was substantial enough.

The old O-ring was very hard and brittle.
Simply unscrew the bolt just enough to expose the O-ring. You'll want to use an 8mm hex on a 3/8 ratchet to loosen the bolt. It helps to have a pick hook to get the old O-ring out, but you could probably just cut it with a razor or exacto knife.

The new O-ring will be a bit of a stretch to get into the groove, just be gentle and work it over the bolt head and into the groove. Now snug it down, then torque it to 36ft/lb.

been a few threads on this in the last while. Consensus was to loosen the bolt just enough to see the o-ring behind it, pull out the o-ring and replace it. Like mentioned above if you loosen the bolt too much or try to remove it the pulley will drop parts below which will be a problem.

You could clean the bolt and use liquid gasket. No more leak. Worked like a charm for me.
