mine does the same thing.. in fact mine was leaking pretty bad. But before I jumped into replacing the valve cover gasket (most common cause of oil leak) I check the bolts and they were all finger tight or less. I tighted them up and a mentioned a few months later they were a bit loose again, though not as much as originally. I have been told this is fairly common. I dunno though, I just check them at every oil change.
Could you replace the bolts with ones that are case hardened, or would this not be a good idea due to different types of metal? My valve cover bolts are somewhat boogered on some of them. I understand that the 85 is 7 pounds on the torque wrench. If this is the case, I would replace as many as I could.
I will have to get some of the Loctite. Either way, more tools to make the job easier.
