Priming LPOP and HPOP

[gnxtc2]

I am getting to drop my motor back in.

I replaced the oil pan (reason for pulling motor), LPOP (Melling), HPOP (Honey Badger), Injectors (PIS 175/80s), balancer (Fluidamper), valve springs (Comp 910s), pushrods (Smith Brothers), oil cooler o-rings, oil/fuel plugs on the head, water pump, passenger side manifold, motor mounts and eliminated the EBP sensor/tube.

I checked the oil pickup tube and it was fine.

Is there a way to prime the oil system both high pressure and low pressure while the motor is on the stand? I guess I can fill up the HPOP resevoir and rail while it's on the stand.

Thanks

just fill the rails and hpop res. I turned my motor over by hand about 15-20 times before hitting it with the starter, check the res filled again and then cranked still she started.

You know that the EBP sensor and tube is needed for the transmission right? It uses that signal to decide engine load for shift firmness... Trust me I learned that the hard way.

Depends on the tuner. Quite a few tuners write so that EBP does not come into play.

Pack the lpop full of grease or vasoline and it should prime right up.

I used the Lucas stuff instead, looks like honey. I was afraid that the injectors might see the grease/vasoline since the HPOP gets unfiltered oil.

Tuner told me that sensor only controls the EBPV and has no other use. I've had mine disconnected for 10 + years with no ill effects whatsoever.

I am not wanting to start a tuner war but I think my experience is note worthy...

So in June 2008 I get a chip... @115k miles after 6 months I lose the stock transmission(135k ) I have a amaco rebuild and go on my happy way to 2011... 165k miles I developed a hard 3-4 shift. Like someone is kicking the backside at anything under 1/2 throttle... I live with it until I feel some slipping and decide to replace my TQ during a annual fluid change.

2012 I start to build up my truck I start with my own efuel system, 17* hpop and epbv delete and .84 housing ( originally installed 2009 ) so I figure no epbv no need for the sensor...now my trouble gets worse. I send chip back to Tuner for update and get it back and I feel like the trans is about to blow Again...

I drive like this until march 2013. I meet a guy willing to guide me on the ways to make a truck faster... I start with new tunes. And from the first drive I notice way better idle quality and NO TOUCHY PEDAL and much smoother shifts. But still a decent hard 3-4 shift ... I learn from said person that the epbv helps with transmission deciding engine load... I put on new tube and sensor and AMAZingly it shifts FLAWLESS...

And to this day living at 360-400 hp it still shifts wonderfully. Maybe it is tuner dependent idk but I found out I really needed it

The sensor DOES need to be plugged in, but it doesn't need to be functioning. For years my tube was plugged, so i rigged up a sensor that was tied into the MAP line and noticed 0 difference. Now if you unplug the sensor completely it causes the PCM to freak out and screw with stuff.

Also, I have yet to see anything in Minotaur that connects the EBPS to anything. My truck does have a funcitioning tube/sensor, but only because i wanted to be able to see EBP.




As for the priming, all i did was soak the LPOP in oil before installing it, where it sat on the stand for several weeks. In the truck i left the glow plugs out and cranked it for a while. Put the plugs back in, cranked a little more, and it fired up. With the glow plugs out it spins over a lot faster with less stress on the starter. With this method it fired up surprisingly quick considering it still had the stock mechanical fuel pump.

My buddy used oil and we couldnt get his to go. So we took it apart, put red assy lube on the lpop guts, dumped a couple extra qts of oil in and jacked the back end up. Fired right up.

The ebps controls how the truck fuels and some other things, however, when I installed my headers, I decided to completely do away with the sensor, and left it unplugged. I noticed NO issues what so ever. Even when I returned truck to stock, I left the sensor unplugged, no tuner, bone stock other than 38r and straight pipe, still noticed NO difference.

Yup, all it does it control the valve.
It'd be great to hear from the top tuners to confirm this (I spoke with several tuners years ago about this) to let you guys know.

I do not specifically remember what tuner (s) said it controls fueling, but I do remember it was a tuner that claimed it controlled fueling tables and other things. I myself have wondered if different pcm's respond differently to the ebps being plugged in or not. I stick by what I said about not noticing ANY diffenence in anything going from it plugged in to removing it. And iirc, the ebps and ebpv are NOT related, but i could be wrong on that one. thats why there is an ebpv solenoid, and think about it, ford went on to use it on the other power stroke motors, which had no ebpv's. Another thing ive noticed was the t444e's dont have the ebps either. Not sure about the ebpv or solenoid though. I may dig around and try to find old threads i researched before i made the decision to remove the sensor.

Heres one of the threads I remember reading.
