So leak is solved and it’s running well again?

Great news!

 

As of now, yes!! The leak was the crossover line that I fixed the other night, and about an hour ago I figured out what was causing it to run like an F-Poo50 Pooper Doodie 💩

Ugh, I'm almost too embarrassed to admit this... it falls under the 'Only MotorCraft/International/Ford sensors' umbrella

Today I learned that the oil pressure sensor (the one on top of HPOP/underneath Powerstroke cover/bracket) plays a MASSIVE role in oil AND fuel pressure and if you ever want to know the easiest way to make an excellent truck run like absolute rotten ***, just throw one of those 10 dollars Oil Pressure Sensors from eBay on there.

I put the old sensor back on there, and mid split second crank I could already tell my baby was BACK. She's alive again! And without the lame crossover line leaking/sapping energy anymore, she's got the pep back in her step!

It was that easy. And to think of the amount of times I emptied fuel bowl/dismantled FPR/changed housing and spring trying to chase that cackling/clattering ghost

The important part is that it's over!! And now I am locking my engine compartment whenever I am at home and am bored lol. Once again, thank all of you wise gents for your assistance and support! I ain't the sharpest spoon in the shed, but I'm doing asbestos I can!

 

Thanks for the update! And for being honest enough to share the final fix. It happens to all of us. But if folks don’t tell then other people don’t see the answers they need. Which is why I’m going to link your last post over on a thread where a guys truck is having trouble once it warms up. Maybe his is as simple as the oil temp sensor as well.

Congrats!

Now to go find that thread…

 

Not the temp sensor!! Thats drilled into the side of the HPOP Reservoir! The PRESSURE sensor! The white sensor that's drilled into the top of the Reservoir! I am 99 percent sure you know that and just had a brain fart, but just want to clarify!

 

 

Maybe brain fart is my new nickname.

I wouldn’t guarantee knowing anything anymore. Too busy and tired, brain is fried. For some reason when I read your post it was totally “temp sensor” in my head. Oops. Thanks very much for clarifying and straightening me out!

Now, I’m really surprised an engine oil pressure sensor would cause running issues. I learned something today.

 

Hmmm. That's weird. Thats just the low pressure oil sensor. It's just a on off switch basically that's tells the oil pressure gauge to show "normal". It doesn't do anything else or go anywhere else but the cluster.

 

Good job, sir! Although I agree not to run a cheap ebay part, I think it may have been coincidence because that is not connected to the PCM. Unless the ebay sensor was leaking, you could put a plug in that port and leave the pigtail disconnected and the truck wouldn't know the difference...

 

​if I didn't know any better, I would say that sounded like a CHALLENGE. Alls I knows is the second I swapped that part out for the old one, my clatter/cackle/struggling on the freeway (original problems that this post originated from) immediately disappeared.

I wouldn't put it past crappy items from eBay to be extra clever when it comes to finding a way to make your truck run like crap. If I get her out on the open road later today I will make sure to film it to showcase difference. Regardless of the reason why, my truck's running fine and I'm as happy as a mud covered swine! 🐷

 

So I return hat in hand to you gentlemen... you were right. I'm not sure if it was just the placebo affect making me think that removing the eBay part would make it run better, but that wasn't the culprit. Fortunately I got all my ducks in a row!

Fuel Pressure is golden! 67 at idle and around 52 at WOT. No more fiddling with that damn regulator for me!

Oil Crossover IS installed! More embarrassment here... it wasn't where the fitting goes into the engine, it was where the crossover connects to the fitting that was causing my leak. The reason I couldn't see it is because it was only happening under acceleration and not while idling... I found this out by using my bore camera while I went for a drive. She was gushing up a storm!

Last but not least, the main issue I was having problems with, the lack of power... so it turns out that my V-Clamp (see pics) that was holding the spider to the turbine housing was absolutely shot and causing a massive boost leak. I got the proper one on there from RiffRaff now, and got my power back!

On a side note, I feel even more like a d**k cause a couple months back I was giving a guy a hard time for what I thought was just a standard wormtail clamp (like the stock ones around your orange plenums) he had holding spider/turbine housing together because my V Clamp didn't look like that, and the beginning part on the proper clamp does have the wormtail clamp appearance.

So if you're reading this, sorry guy!

Anyways, just wanted to follow up. Thank you gentlemen for all your patience & assistance! Until next time, keep on 'Strokin!


The old clamp all chewed to hell.

Yeah, that wasn't cutting it.

New clamp!

 

It takes a big man to admit he's a dumba**.

What the heck is that Green Goblin DNA there on your old clamp.

 

I just came across your post.

I recently had to replace the oil gallery plug seal on drivers side by firewall on my recently rebuild engine (we won't get into that story)
after doing the work, I dumped a bucket of hot soapy degreaser to rinse off what I could. the next day I went somewhere and noticed it acting differently and doing odd things. Thinking to myself, did I screw up and not keep the gallery clean having a chunk of something clog an injector, WTF.

I ended up having to go to Denver to pick up my nephews boat and bringing it to my sisters because my nephew is working in Oklahoma right now. My sister is like...what''s going on with your truck, are we going to make it, bla bla bla. Guess i'll have to figure it out.

everything looked good, didn't see anything, IDK. Finally figured it out. The temp/pressure sensor just above the IPR on the res, the locking mech is broke on the connector and I guess the force of the soapy water was enough to dislodge it enough to make a poor connection. I ordered a pigtail, soldered and heat shrank it..all is good. Who would have known.

I found info on the internet about this issue but I don't remember all the details. I also don't remember if I was getting a code or not, most likely. But sensors we wouldn't think would wreck havoc certainly can

just thought I would share my experience after seeing your post

 

I think maybe you figured it out but the old clamp you’re showing is for the back of the turbo. What clamp do you have on the back?


I have heard of people having running issues due to the oil temp sensor. The pressure sensor was a new one to me. But I guess it was a false alarm after all.

 

Lol, I went through a 'green' phase for a while, it's paint from the spider. Fortunately everything is almost back to normal.

 

Good question. I am guessing the PO got the clamps mixed up when he was gutting the EBPV, I'll bust out my mirror in a moment and see what the dillio is.
