Loose injector adjustment

[AussieISX]

If you run them too loose, they will not seat tight tight enough on the lower set on combustion. This allows combustion intrusion into the metering circuit in the injector. Not only will it fill with soot and block the metering check valve it will also send combustion gas through the remaining injectors in the firing order in that bank . Stupid idea in my opinion. The rocker lever is already over coming spring pressure to plunge the injector, by loosening the height setting your not relieving pressure from the cam , just ruining injectors with soot and combustion gas . I actually set mine slightly tighter than spec for the reasons I listed.
