Cm2350 leak down failed

[Rawze]

next step is to loosen and re-torque all the quell tubes then do the leak test again. Maybe you get lucky and it is simply an improperly torqued feed tube.

.. and no, you will not see fuel anywhere due to leaking injectors etc ... as leaks will drain back into the return lines internally to the head.


After replacing the pressure relief valve, and re-torquing all the feed tubes, and getting the air out of the lines again,. etc.. if it still fails then its time to start capping off up to 3 injectors at a time to find the injector(s) that are leaking.

Leaking injectors are nothing to play with or to ignore. They can cause valve seats to get eaten up, cause a dropped liner or other combustion related damage, and eventual severe engine damage will be the result.
