I did a compression test this evening, here are the
results. (#7 is the plug shown above)

cylinder psi psi cylinder
  1------> 160 160 <-----2
  3------> 145 165 <-----4
  5------> 153 140 <-----6
  7------> 130 158 <-----8
  
* #7 after I added some oil into the cylinder: 135

So how does this look? I've read that the lowest
reading should be at least 75% of the highest reading,
130 is pretty close to that point. After 1 week # 7
was very dark compared to the others. Could a valve
that's not sealing all the way cause something like
this? What about a misadjusted rocker?
