Can anyone give me tips for finding top dead center for all 8 cylinders. In the process of taking the VC’s off and performing a leak down test

Not the most technical of ways, but can pull a glow plug out and put a wire rod in and turn the motor over til it starts to go down

Bump it over till both rocker arms are loose atthe valves/pushrods. That will verify tax compression. Another way is to put your leak down hose in the glow plug hole and put your finger over the end. Bump it till it blows air out.
