Good morning, everyone!
Does anybody knows what signal splitter I can use with a Cummins camshaft position sensor?

7.3 Powerstroke oil leak

Bob Joe — Sun, 03 May 2026 01:46:03 GMT

I�m having the common oil leak on my 2001 F250 7.3. Most research says the turbo pedestal is the likely cause so I included the photos I could have that area. However, the oil also seems to leaking towards the front of the engine valley near the fuel filter. Hard to see in my photos but the whole engine valley is soaked with oil. Isn�t leaking a ton just has built up overtime. When I park there will be just a few drops on the ground. Any past experiences or ideas would be greatly appreciated!

Duramax DPF Delete Kit � Worth It or Not?

zunepuh — Tue, 28 Apr 2026 14:01:05 GMT

Hello everyone.

I'm considering options for my Duramax and have come across DPF delete kits. I understand they involve removing or bypassing the diesel particulate filter system. Before I even think further, I want to hear from people who have experience with this setup.

What are the real-world pros and cons in terms of reliability, fuel economy, maintenance costs, and engine performance? Also, how do emissions regulations affect ownership where you live? Is it worth the risks and potential legal issues, or is it better to stick with stock emissions equipment and proper maintenance?

Any advice would be appreciated.

New ICP, HPOP, and IPR still having problems

Ozz — Mon, 20 Apr 2026 01:38:30 GMT

So, my HPOP went out last year. I replaced it and the truck seemed to run fine. I noticed a "hickup" driving home one day. Truck died, then started right up. Happened again and then would not start. I thought the HPOP died, I got a new HPOP from one of the top recommended vendors mentioned here. Well, I tear into the engine to find the top O ring from the J tube had looked like it failed on one side. I then did a pressure test to find the passengers side oil rail also had a failed O ring. I replaced everything! Did a pressure test and the truck had no leaks! Now I start the truck up and it idles fine for one minute. When the truck idles fine for the one minute, my truck starts hunting for a smooth idle.

KOEO-
ICPv - 0.2
FMP - 48v
Ficm sync- 0
HPOP- 78.7
IPR- 14.7
When I start the truck and it runs fine for the short minute with a smooth idle, Torque shows me the following:
ICPv- jumps to 1.9 and steadies at aprox 2.8- 3.2v
IPR- 52%
HPOP- 2500
Ficm sync - 1
Ficm voltage - 48

Then, the truck starts hunting for idle and sounds terrible!
ICPv - 1.7
IPR - 27.5%
HPOP -933 psi
Ficm sync - 1
Ficm voltage - 48
ICPv 3.7v and runs with a smooth idle, FICM sync = 1, HPOP is showing about 2500psi, FICMv 48. Then the truck starts hunting for an idle ICPv is about 1.7v, IPR is 43-54%, FICM sync - 1,

I do not know why my IPR is high when the truck first starts and then drops to where it should be at idle and then runs like CRAP?

I need some Help please :)
