Cm570 engine brake vibration and weak jakes

I could swap injectors over from another cylinder before buying a brand new oem one just to see what happens to the bubbles.

Im wondering if it could be a crack in the head?

be sure to adjust the overhead valves and injector rockers to correct torque before doing the tests as well. It can effect the test.

I adjusted everything after swapping injectors, still stuck with the bubbles

I have done that test many many times over the years.

Only conclusion that I would assume is that then you have leaky injectors or possibly a cracked head.

I would point towards leaky injectors if they are not OEM. I am not a fan of repaired or non eom injectors or other critical components like that. They don't last for s#it and it always costs everyone a lot more moneys in the end, in one way or another.
