I am currently figuring out how to make the 14mm bent wrenches to adjust the valve lash. I am using .014" for the Ex and .004" for the intake. What do you guys use for TDC? 90*(deg) to the rocker pad?

It knocks at all temps, 5w-40 oil, Oil level has at the high (full) mark the entire time, just replaced filter, I don't know the condition of the pump. This 617 has ~170k, and seems to run fine otherwise.
