I didnt

So I guess I'm going to have to,... also I cant get the bolts any tighter than 15lbs, so what does that tell me? That the threads are stripping? I didnt turn the bolts anymore. What about the black cap things on top of the cover? There is oil coming up and out of that too. Just a little though. Also,... amuse me, how much does a good used head or even a new one cost if they are indeed stripping?
