Finished a rod bender 603 rebuild with an '87 300D block & 140 350SD head.

Engine runs fine & drives great but is very noisy. It sounds like injectors nailing, but these are known good injectors

I know the early & late injectors are set to open and different pressures, could that be it? Timing issues?

Any tips?
