After a little research I found that all oil is dialect and won't harm electrical components. I think what happened is you just had a bad harness. Just my opinion. But it's a good idea to change out any leaking components.

[@PrabhjotSandhu-tm9yu]

Should've done a bit more research, oil in your harness can deteriorate your wires/ causes short to ground/power also oil can cause resistance in your wiring

Again very great work Pedro. Excellent work to your videos and what you are doing!! Have a question and need your input por favor....Injector lines leaking to DD13 DD15. New lines here in USA are months and months away from receiving.🤨. What makes the 'used' injectors leak when reinstalled ? I have access to 4 used engines here, lines don't leak. (trucks are wrecked)...WHAT CAN I DO, To remove and REUSE these fuel Injector lines and install to running engines. AND NOT LEAK. Trucks in service, have sat for 6 weeks. Waiting for new lines, but months away!!🤨 POR FAVOR AVISE. Allen.

[@CarlosDieselElectric]

Fuel lines are hard to get, the part numbers ending in 1810 are the ones on back order (for injectors 1, 2, 3). The ones ending in 1710 (injectors 4, 5, 6) should be more available. What are your torqueing them down to?

[@allenstautz9506]

@@CarlosDieselElectric Hola again . I have not installed any of these lines ever..these DD13, 15 are my first..EVERYONE tells me. DO NOT INSTALL USED LINES. But with NO SUBSTANTIAL reason...Have installed 'used' lines to John Deere/Cummins/CAT for DECADES...Why not these?? Makes no sense. Are there other seals or method to REUSE lines to make NO LEAKS?

[@CarlosDieselElectric]

@@allenstautz9506 So are you replacing the seals on the lines because they are leaking oil on the outside of the CAM housing? Or do you have a fuel leak?

[@allenstautz9506]

Hola otra vez amigo. These lines leak fuel on the engine in service..But lines have no visible sign of damage..🤔..look the same as lines from wrecked engine..leaks are 5 and 6 inj....the only explanation the dealer tells me is "Can never install a used line when these lines are removed"...but with NO explanation..I am sure there is a method or idea from you to install 'Used lines'

[@davidcawley214]

Hello great video, I currently have a caterpillar excavator that brings up a intermittent fault when tracking. The fault code relates to “engine exhaust gas recirculation mass flow rate, not responding” when this happens, the machine starts to die down like a fuel problem. I think it’s in some kind of limp mode,any ideas where to start? As I say it’s a intermittent fault and will only happen a couple of times a day when I’m tracking the machine. I then have to switch the machine off and let it reset for a minute. When I start the machine back up it has reset and I’m good to go again. Any help with this would be much appreciated.

[@CarlosDieselElectric]

I am not to familiar with CAT engines. Do you have the software for CAT? You might want to check with the Delta Pressure sensor for any blockage on the ports where the sensor sits. Also, check with Adept Ape, he has really good knowledge of CAT engines.

[@davidcawley214]

@@CarlosDieselElectric okay, thank you for your reply, appreciated👍

[@alw7810]

Why was oil coming out the engines side of the harness was the oring bad. Paccar has oring around their injector harness going into the side of the block below the valve cover on the driver side.

[@CarlosDieselElectric]

Eventually the seal or orings start to leak due to heat and age.

[@OG-dn4fo]

I replaced the delta sensor on mine. My question is should I calibrate it or no? I just replaced it before it gave me any problems, old one was not bad but still replaced it.

[@CarlosDieselElectric]

It is probably best to calibrate it.

[@bekrakhimov2466]

I am just curious how much the bill was😅

[@Hearmeout503]

[@saulthompson6613]

Isn’t motor oil dielectric and the whole idea of oil contamination moot? Injector harness has open connections and floats in oil and it’s supposed to do that. All signalling is ok. Oil contamination with wear metals doesn’t affect anything.

[@kennylaporte9850]

I noticed he didn't answer you..

[@CarlosDieselElectric]

Saul, you are partially correct. The oil in the injector harness isn’t the problem. The problem is mainly when the oil makes its way into the main engine harness and down towards the MCM/ECM. Then you will have issues with resistance, fault codes and other issues.

[@aguilarreal2124]

Do you think the oil can make the bad ECM

[@CarlosDieselElectric]

Yes, false contact can cause many issues. I have had to replace the MCM due oil contamination.

[@CarlosDieselElectric]

Possible harness issue at the ACM, ACM harness or One Box harness. Try to find someone that can connect to using the DDDL software and reading the codes to be sure. Are there any other fault codes? Active or Non Active?

[@jorgefacio690]

@@CarlosDieselElectric no that's the only active code it shows.

[@CarlosDieselElectric]

@@jorgefacio690 sounds like a harness issue. Does your truck have the small black box on top? If it does, look inside and check the harnesses.

[@jorgefacio690]

@@CarlosDieselElectric where would that black box be located?

[@CarlosDieselElectric]

@@jorgefacio690 I know EPA10 has the black box on top of the One Box 2011-2013. This has the two harnesses inside. Then around 2013 Detroit changed it to having the harness on the outside of the One Box. So depending on your 2013, you have to remove the passenger side fairing in order to see.

Is cleaning the mcm harness enough to fix this without having to buy a new one? If not why?

[@TommyG11814]

Great video, and nice clean work.

[@CarlosDieselElectric]

Cleaning the MCM connection is a temporary fix, it might work for a bit but the problem will definitely return. I recommend to just replace the contaminated harnesses and get it fixed.

[@kennylaporte9850]

Does the oil leak thru the harness to the ECM or on it? Is the short at the ECM or in the injector harnesses? I'm confused as to how the injector harnesses cause a EGR valve actuator code.

[@CarlosDieselElectric]

Oil at the injector or around the injector harness is normal. It should be contained within the housing, but over time the oil will make its way into harness (thru) via the injector harness and then makes its way into the main harness at the connection. That is where the problems start, oil will make its way down towards the MCM and then can contaminate or damage the MCM/ECM. The reason I change the injector harness in addition to the main harness is because this is the source or point of entry. Now if you want to only change the main harness that’s fine. But you are not addressing the root cause. So I will always change both harnesses. The problem the oil cause down at the MCM is it starts to make false contact. Hope that answers the questions. I know my answer is long.

[@kennylaporte9850]

@@CarlosDieselElectric yes thanks. I couldn't get a main harness thru dealer it's on back order. Will my truck be ok to run until it comes in? After I change the injector harnesses I mean.
