• clearance on 2 of the intake valves is a little big... just out of spec, but that wont effect compression. ill change them, but not yet.
  
  i got # 3 and 4 done but couldnt fit the adapter between the pump and #1 and 2 so ill have to figure something else out. looks like i might have an adapter for the injector that im gonna have to try out and see if it works.
  
  so far i have about 540psi at 3 and just a hair under that in 4.
  
  so, half of the motor is good, anyway...

• had a spare moment today so i checked the compression
  
  im getting ~500psi across all 4 cylinders.
  
  when i pulled the 2nd injector, its tip was covered in oil...
  
  any ideas? valve stem seal?

• try bumping the timing down to 0.90
  
  Did you replace the heatsheilds after the compression tests?

• ill try bumping the timing down a bit.

• ordered a set.
  
  also have valve stem seals on the way and the special tool to press them in without removing the valve/head.
  
  we'll see how it all goes next chance i get to work on it
