Aren't those bolts torque to yield one time use only?You could pull the valve cover and retorque the heads. Don't over torque them, just make sure they are tight enough.
The point is torque to yield bolts cannot be loosened or tightened any further otherwise they risk being ruined. You either loosen it all the way and use a new one or leave it as is. Is that not the correct procedure?Yes. What's your point?
I would not even call that a weep.
Nothing stays looking new.
Clean it off and monitor it.
If you are not losing oil or coolant or having overheating issue, dont look for issues that are non-issues.
Ps:looks like a very minor oil stain from the timig chain area.
I was thinking about this some more this afternoon and you are correct. I forgot that the bolts are not just torqued to a set number, but to a set number and then an additional 1/4 turn or 1/2 turn or whatever.The point is torque to yield bolts cannot be loosened or tightened any further otherwise they risk being ruined.

I'm not worried about the stain fellas, I just want to know what caused it because I'm curious. I thought it might be oil or coolant, but I wasn't sure. It just seems odd that an 31k mile engine would have a leak of that type in that area. Couple that with the fact that it is not wet which means that it isn't continously leaking is what threw me for a loop. I appreciate the replies though.
It didn't do anything since it was so dry. All I did when trying to clean it was wipe away a small amount of dirt so to speak. Whatever has leaked has "soaked" into the head and only the stain remains.When you cleaned the area, did the water bead up on the strain, or mix with it? If it beaded up, it’s oil based. Mixing would be coolant.
The PCV does draw a vacuum, however, I do have a catch can between the exit port and intake. Would that cause enough pressure to build up and push some oil between the head gasket? I didn't think it would, but I could be mistaken.I wouldn't call it a leak; more like a bit of oil "sweat" from the driver's side head gasket. I wouldn't be concerned about it. Just monitor it from time to time and see if it gets worse.
It's definitely oil. There's no coolant in the valley of the block where it would normally accumulate if it leaks from a heater hose, and the coolant passages in the head are further in closest to the combustion chambers.
Since the driver's side is where the PCV hose is situated, check it for any blockage and also apply vacuum to the PCV port in the valve cover to ensure that it draws crankcase gases.
You are correct. After some thought, I came to the same conclusion. Time wears out everything regardless of use31K miles but its 10-15 years old. Engines, transmissions, rear ends, pumps... all weep power, as I call it, over time. Seals and gaskets dry up and get worn.
