2004 225 oil injector issue

[27CapeHorn]

E225FPXSRB
Engine has been running a little shaky and using way more oil then the other. Connected software and oil injector solenoid opens and closes with the test (clicking sound every second or so) There are no active or historical oil faults logged. BUT, on the monitor tab of the software the oil fault tab at the top is highlighted pink/red. Oil pressure on software when engine running is 3.8 which matches the other engine at idle. I would think the injector is stuck open which would dump oil without a check engine alarm/fault but the test of it makes the clicking sound. I’ve had injectors stuck open and dump oil before but when conducting the test the solenoid would not open and close. Sorry for rambling. Is it possible the injector solenoid would test normal by clicking and still have an issue dumping oil?

Clicking only tells you the coil was activated. Doesn’t mean the injector is fully opening or closing

Ok thanks. Replacing injector now. If it’s not this I’ll change the in line regulator

 

[27CapeHorn]

Ok I swapped out oil assemblies and computer still showed oil pressure in red (fault) and engine still smoked (never smokes with xd100) then moved on and swapped out return regulator and that didn’t change anything as well. Next step will be swapping the EMM to see if issue follows EMM. After that I’m out if possible answers

 

[27CapeHorn]

Swapped oil assembly, return line regulator, EMM, PDP. Still same “oil system fault” highlighted on the MONITOR page of the laptop software and still dumping oil. Anybody?

I won an all expense paid trip to the Midwest last week to trouble shoot what turned out to be a water flow sensor stuck open.

The computer said everything was working properly. Water flow was good yet the system shut down from over temp.

Moral of the story….don’t assume anything. First thing I check is the operation of the sensor throwing the alarm

Did you swap the injector? Some time the pintle tip breaks

And sometimes i's mucked up and needs to be cleaned. Btw, I always understood that all injectors needed to be changed together, as they are matched sets. Maybe that's wrong.

Nope-----You have to take the identification ( co-efficient ) of each injector.----Then you have to match each one with the ECU so that correct amount of fuel is injected.----So yes you can replace just one.----It is just not as simple as installing a sparkplug !

Ok let’s back up lol. Oil injector system runs on 1 injector has nothing to do with fuel injectors. I’ve swapped complete oil assemblies including the oil manifold and issue stayed with engine. As for the “sensor” I believe it’s in the EMM and I swapped EMM’s already and issue didn’t follow the EMM. It’s ok to temporarily use an EMM that isn’t coded for the fuel injectors just to start engine and run at idle for a few minutes as well so no issue there. As for the t-stats or water pressure regulator up top even if it was bleeding by the pressure valve keeping engine cooler then normal I do not see it making the “oil fault” activating and doubling oil into the system. I understand the engine may use a little more oil when engine is cold if that’s what happens however dumping oil at double the rate (compared to other engine oil usage) and activating the “oil fault” don’t seem to be related to temp of engine. If I’m wrong on that that’s perfectly fine and I’ll gladly accept advice. As for now I’m stumped on what the issue is.

Wow. I just found a 2 year old article from Crowley Marine that states to ignore any “oil fault” tab in Orange because the new softwares don’t communicate properly on that tab with the EMM and it will remain on for engines 2002 and newer. My starboard engine is 2004 with the issue while my port is 2001. Hmmm. Maybe I need to run engine a while again since I’ve swapped oil assembly and regulator and PDP to see if issue was one of them and not rely on the oil fault tab as long as the active fault tab stays green.

The EMM is a "black box" computer. I believe #31 on the parts list is the oil pressure sensor

Have you checked the operation of the oil sensor?
Just become the SW doesn't clear the alarm properly doesn't mean that the sensor is not the probelm.

 

[27CapeHorn]

The alarm part is moot at this point because it’s not functional with the software as I can tell now and will always be highlighted as a fault. I have no codes on the EMM actually to clear. The “oil fault” tab isn’t a code that shows up. I believe the codes would more so activate with low or no oil and the EMM may not pick up an issue with over oiling. As for the oil sensor what part do u mean? I changed the entire oil assembly which includes the oil pump, pressure switch, oil injector and the oil manifold. Where can I find that sensor ?

 

[27CapeHorn]

Ok yes part 31 is the pressure switch which I changed with the entire oil assembly
