HPOP 7.3 Powerstroke

[BTLowry]

How hard is it to change yourself?

Require any special tools?

Just had my oil changed Monday and noticed last night when I let the dogs out that there was a puddle under the truck. Checked and it was oil, looked with flashlight and some on filter so i thought maybe they did not tighten it good and had wife carry it by first thing this morning. They looked and said oil coming down back of block so i told her to take it to mechanic. Got a call this afternoon that it was pump.

Looks like my safe money will be used to buy a new oil pump

most likely not the pump. its really common on the 7.3's to get oil running down the valley. there is a "non-servicable" plug that is most likely the problem. you need to pull the hpop to replace it. while its out you can replace the rest of the o-rings

and this

another option is to get the plug and the "mechanics kit" it has most every oring you need to replace on the hpop, fuel bowl, and turbo pedestal. that the route I went.

Turbo pedestal orings cause that also. Highly unlikely its the hpop.

Edit. If the hpop goes bad, there won't be enough pressure to fire the injectors and the truck wouldn't run, or would run real bad. Leaking wouldn't necessarily be a symptom of the pump being bad IMO. Thy should've checked the pressure it is putting out.

Thanks I will check that out tomorrow

On a side note, I trust the mechanic. Someone I know who has always done me right. Just trying to see if I can save some money doing it myself.

If the HPOP is out then you will not have any oil pressure and the truck will not run and or if it does it will run like crap and you would have noticed that before you noticed the leak.

The OEM HPOP's have a faulty STC fitting that go bad. 9 out of 10 times this is the issue and it is not the HPOP itself. Most shops are good about saying its the entire thing and getting the extra grand from you for a new pump and then just replacing the fitting. Which is only costing them about $60

Sadly even if it is just the fitting and you can find a shop who will be honest, they still have to pull the HPOP to get to it. It is labor intensive and your gonna pay no matter what if you have someone else doing it.

The HPOP itself is not hard to take out. Its everything else you have to pull to get to it.

I am also referencing in my head a 6.0.. The 7.3 engine is a little different set up but still have to pull a bunch of crap to get to it.

I was never worried about tearing everything out. It was always putting it back in correctly.

If you do decide to do it yourself, Be careful taking out the turbo as the vanes can crack very easily if you are too rough or pull at the wrong angle. Also if you do DIY make sure to take a video of everything you do pulling it out notating verbally how many nuts, bolts or screws and where they were. Just general stuff to help you that you can go back and look at if you get stuck or not sure.

Last and final. Have lots of Cold Adult Drinks on hand to take the edge off and lots of patience

If you decide too. Let me know and I can get you a link to the Ford House Coffee table books that give you a full run down of every inch of your engine. Its what the ford techs use and learn from. It was very helpful for me.

I do not personally have the link anymore myself but can get it or put you in touch with who does.

Not saying anything negative about the mechanic but the hpop most likely does not need to be replaced. Its like having a soleniod go out on a starter. Replacing the starter will fix the problem, but you can also just replace the solenoid

I'm no mechanic but I have done all my own work on my 02 F350 7.3 as well as my dads and my brothers. There are diy instructions at the site in the link I sent and if you get in a snag you can call them and they will walk you through

You don't have to pull the turbo in a 7.3 to get the hpop out, but those fittings are a pain to get to. It would be worth it to have someone change the orings for you if you've never worked on it before

Can you see the plug without pulling the HPOP?

It has been a little slower starting lately but I thought it was glow plugs and was planning on replacing them.

There was oil on back of motor and oil on front, most on back but a little on front end.

Sad thing is I started to sell it about a month ago but was not really motivated. Guess I should have been but it is paid for and I really did not want to take on a new payment.
Still cheaper to fix it than to make payments

It's been a while, but if memory serves, the plug is on the right rear side of the hpop when looking at the front of the truck. There are two lines right above it that you have to get off to get to it. I've done it without pulling the pump, but had to bend and grind on some tools to do it. Go to powerstroke.org and look around. I bet there are some write ups

Go to this link and scroll to the bottom of the page. There are pdf's with diagrams explaining how to change the plug and o-rings. He sells the tool to release the hose as well or you can make your own pretty easy

Your preaching to the choir brother. Had a 6.0 for almost 2 years and put well over 5 grand into and most of that was in the first year. But mine was not paid for. Got sick of that mess. Had about a 6 month stretch with no issues finally and then it was starting to act up again so I sent that bad boy down the road.

Thing about oil leaks is, there are so many parts and pieces for it to hit and change direction. I had to trace fuel leaks for the first 3 weeks of owning mine and thought I had it figured out until I realized it was draining from above and working its way around where i thought it was coming from.

From what I understood from my mechanic is, the glow plugs basically are just mini heaters to help start the engine when its cold. They will not cause a issue unless its like below freezing if you have issues. I drove 2 years with the #5 glow plug out because a $20 plug was gonna cost me $200 in labor to get to it and then you should just change all the plugs at that point.

I never had issues starting with bad glow plugs..

If your HPOP is bad.. When you turn the ignition over to power but not starting. Your oil gauge should be reading. When you turn it over look and see what your oil pressure is. More the likely it will show less then normal pressure which will indicate of leak of some sort.

If your HPOP is bad you will have no oil pressure and will not be able to start your truck.

From what I have learned anyhow. But I am no mechanic, Im too honest
