Fresh mill. Bad happenings? What to check for?
If you don’t have access to a known quality pressure tester or a loan-a-tool that doesn’t actually leak itself: If you’re concerned about the engine possibly consuming coolant use a machinists ruler and measure how far down the coolant is (always fully cool) keep the ruler against the lower and upper edges of the fill/cap fitting so you’re always measuring from the same angle. You need to temporarily use a catch can in place of the recovery system so that prior to measuring, after running for a period, you return whatever coolant from the catch can back to the radiator and then measure again. Monitor it after some good run time. Then you will know if it’s being actually consumed by the engine (assuming no external leaks) That’s how I’ve done it in the past.
