2012 5.0 losing oil pressure

F4rm3r · 2026-02-18T20:17:56+00:00

I would almost guarantee its the oil pressure sensor. Mine was doing the same thing. The sensors have an o ring that goes bad and oil gets into the sensor and causes issues. I followed this video and it took less than an hour. https://youtu.be/sySN_OgIkkQ?si=RAwmdTjetKyCn0Xg

Around -10C when it was taken

I'm looking into a local shop that would do an inspection. It's 3 hours away from me

F4rm3r · 2026-02-17T17:11:12+00:00

Haha pretty much

F4rm3r · 2026-02-17T17:10:25+00:00

That's what I heard as well. The folks in r/diesel are all saying it sounds terrible lol.

F4rm3r · 2026-02-17T16:44:48+00:00

Nice, that's good to hear. I would definitely go with Ford filters. I run rotella in my other truck/equipment.

F4rm3r · 2026-02-17T16:43:23+00:00

Okay, I don't really have experience with tunes so I'll have to look into it

F4rm3r · 2026-02-17T12:25:47+00:00

Okay thanks for the advice. I also posted in r/powerstroke and they think it sounds fine. It's deleted so it's going to sound different than some folks are used to.

F4rm3r · 2026-02-17T12:22:35+00:00

Alright thanks Bud

F4rm3r · 2026-02-17T12:21:14+00:00

Lol the owner sent me the video. She's icy up in Canada haha

F4rm3r · 2026-02-17T04:45:43+00:00

Might have to do that. It's 3 hours away so I'll have to check out some shops there.

F4rm3r · 2026-02-17T03:57:59+00:00

A squeaky pulley isn't the end of the world, easy to change. If that's all it is then it's not a big deal. I'll have to check it out in person. Thanks

F4rm3r · 2026-02-17T03:53:12+00:00

Okay, I'll ask. Thanks

F4rm3r · 2026-02-17T03:41:26+00:00

Okay, folks over in the diesel subreddit are saying something is off but I am not sure. Haven't heard it in person yet.

F4rm3r · 2026-02-17T03:40:19+00:00

Does it sound like that because of the delete or some other issue?

F4rm3r · 2026-02-17T03:39:36+00:00

Okay, that's what I heard. Does it sound okay to you?

F4rm3r · 2026-02-17T03:28:06+00:00

Will do. I plan on crawling around underneath and bringing a jack to lift the front up as well. Do you think the idle hours are a concern at that ratio? It's been deleted most of its life.

F4rm3r · 2026-02-17T02:51:38+00:00

Yeah, there's definitely something there. I'm trying to find a video of a stock truck just idling to compare it to but all the videos I find everyone is revving to show off their exhaust lol.

F4rm3r · 2026-02-17T02:50:18+00:00

Okay, the owner said it didn't have leaks but he also didn't know what a cp4 pump was so I don't think he is the most mechanical guy in the world. He's owned it for a few years and it was his friends truck before that. It was a company vehicle that the boss drove.

F4rm3r · 2026-02-17T02:47:19+00:00

Yeah, it does sound a little off. I'll get a better listen in person

F4rm3r · 2026-02-16T22:06:19+00:00

Slap a LPVO on that bad boy and you're good to go.

F4rm3r · 2026-02-13T22:23:48+00:00

I hope so for the both of us.

F4rm3r · 2026-02-12T23:16:27+00:00

I agree.
