Hello Sir or Madam. Welcome to justanswer!
How low is the compression?
You can do it cold. See what reading you get from the right and left front cylinders. Let me know what you get...
Ok the right side chains have a problem based on your readings.
Engine is ok. The timing did jump so you're going to have to do chains and tensioners. Valves didn't bend or compression would be near zero.
Sorry for the delay....
You need the special tool.....
