I'm having a hard time to find a root cause of leak from injector on cyl 2 on my IO-390 EXP 119. I'm pretty sure the injector is installed and torqued properly. The A letter mark is on the bottom side.
Did a quick test: removed the cowling and covered the injector with a piece of cloth, then run the engine for a few minutes. The cloth was dry, which would suggest that on the ground the injector doesn't leak. Nevertheless after a few hours of flight traces of fuel indicate that something is seriously wrong.
Is it possible that somehow fuel is sucked out of the injector's screen?
thanks in advance for any help
