Hello, I posted this in the f-150 but I have had no responses. I want to install a by-pass filter on my 5.4. I know my PSD had two ports with plugs in them above the oil filter. You just remove the plugs and connect the filter and you are ready to go. Anyone know of some ports on the 5.4 that are the preasure side of the oil pump to connect the by-pass filter? Thanks

 

The closest thing I've been able to find out was a plug on the back side of the heads. However if you find a pressurized 1/8-3/8" npt port, I'd love to know.

 

On the 2V engines,there is a 1/8" NPT port at the passenger side front corner of the cylinder head,and the driver's rear corner in the same location. These are almost at the dead end of the oiling path,right before the timing chain tensioners. They're pretty easy to get to-I've seen the passenger side port used for lube feed on Vortech Supercharger installs. I'm not sure if the 3V has something in that same location-I've never looked for it.

Thanks for the info. I will be sure to check it out. Even if its at the bottom of the pressure chain it will still serve its purpose. Thanks

 

Don't some SuperDuty 5.4's have a remote filter? I know 2000 did. Perhaps this oil filter adapter will work. Don't know for sure.

 

2nd Gen Lightnings also had a filter relocation part. Moved the filter to a space where it was mounted vertically behind the engine I think.

 

My 250LD has a factory remote filter. Infact I have to find the hoses to replace them. One has a small leak.

 

I took pictures through the wheel wells of my 5.4L Superduty. This is the pass side,

This is the drivers side,


The lower plug on the driverside looks identical to the one on the pass side. Is there any reason I couldn't use this one for oil pressure? Or am I looking at the wrong place?

 

You don't want to use the ports on the heads for oil pressure-if you're wanting to install a gauge sending unit. The restrictors in the heads will yield an alarmingly low pressure reading. I installed a mechanical gauge on my Tbird when I was checking for some oiling issues in the passenger side port on the head,and at hot idle,it would read 4-5 psi there vs. 20-25 psi at the OE location. At crusing speeds of 1500-200 rpms,it would read 20 psi when the OE location reported 50-60 psi.

So I am still stuck with Teeing off the stock sender?

 

For an accurate reading,I'd say yes.

I've read this topic, and also did some searching. I am planning to install an accumulator type preoiler to a 99 5.4, installed in an Econoline passenger van.

I tested the system using the 3/8 NPT port on the passenger side aft end of the head.

While I did get a normal oil pressure indication on the gauge prior to cranking the engine (key on, accumulator active), I didn't notice if the oil indicator light went out.

If this engine does have oil galley restrictors, is there a better point to apply pre oiler pressure. I would really like the entire engine pressurized, but could deal with just getting pressure to the main and rod bearings.

FWIW, I was planning to add a "T" in the accumulator hose to monitor oil pressure, but a previous post has me questioning that.

Also, where could I expect to find the OEM oil pressure sender, I believe it on the head, and that was one reason I opted for the 3/8 thread oil port.

Any comments or ideas.

Thanks

Yep, this is an older thread ~ Re: oil port on the passinger side Front corner of the cylinder head ```

Would this be a good point for take off to a Bypass Oil Filter ```

What think you ```

Thanks Richard
