BIG PROBLEM! Would appreciate your input....
I started going through things and did the following:
--Checked compression, both cylinders at 130, from what I read that seems to be good
--Started on the left side, checked rocker end play, set valve clearances and re-torqued the heads, valve clearances were slightly large but all fine now.
Now comes the fun part. The rocker arm clearance on the right exhaust valve was too large and I realized that the head bolt from the upper exhaust rocker block was loose (maybe 10 lbs or something like that). I adjusted the clearance, made sure the rocker arm still moved freely over the entire arc and when I tried to re torque the bolt, the stud was pulled out of the engine. I applied not even 15 lbs of torque and as you can see in the pic, the bolt sticks out further than the others.
Now what to do? I think what I can try is to take the rocker blocks off, tighten two nuts agains each other on the stud and ttry to turn the stud back into the engine case, hoping to catch a thread down there. Now if that doesn't work, what are my options?
