SO when you have them Install a HPOP that Makes it #3 HPOP Of Supposedly the good year!!

I THINKING THE d PLUGS ARE the Leak

the HPOP IDK

IDK if there are other Knock offs or AM for the 05+ HPOP

 

Supposedly, he had to take the turbo off and all in order to discover where the leak was.

I just think it strange that the mechnaic thinks it is not the original.

 

this truck seemed to fail in a couple different senereos so IDK

 

Last 12 months alone:

Head gasket
Rear Engine Cover
Up pipes and other pipes.....

$9200 in repairs plus this one.

 

I'm new to this stuff, but from everything I have read, it is EXTREMELY rare for the 05+ HPOP to fail. Even rarer for multiple HPOPs on the same truck. Frankly, I think your mechanic is not very knowledgable. We have good mechanics on this forum that don't have to tear all the way down to find a leak.

When he says that its not original because of the way the 'hose popped off', maybe he's only ever seen one that the STC fitting was already replaced with the new style? Maybe that's where your leak is and he thinks the whole HPOP is bad?

 

How would you test the actual pump?

 

What was the reason for the replacement of the part highlighted in bold red? An original STC fitting that blew out causing damage to it? Was the STC fitting already replaced at THAT time with the update one-piece branch tube connector? If so, maybe THAT is what the mechanic means, when he states the HPOP is not original???

Coming from a Ford/Diesel/Senior/Master tech who has been working at various dealerships (or is that "stealerships" to some of you???) for over twenty years, I have seen too many area indy shops over-repair these '05 to '07 trucks replacing the HPOPs needlessly. It does make for very good sales for our parts department though I must say.

 

Rear Engine Cover was cracked and leaking oil. Nobody had an answer why, but was told possibly stressed due to head gasket failure and overheat. About 6 months between head gasket ( actually head BOLTS stretching causing head gasket failure) and leak starting from rear engine cover.

My big bugaboo with Ford and their Dealers is that they KNEW the head bolts would eventually stretch and cause catastrophic failure, sued Navistar over it, and did not warn owners to replace head bolts. We were just outside warranty and Ford told us to you know what. I called everybody.

Our truck gets very little HD use. Mostly a family car that we use to haul my son's baseball gear all over town in. We previously pulled a large boat ( well under max towing cap) 2-3 times per year. My husband takes very good care, does all recommended maintenance on time or earlier. Never neglects anything.

Right now, my POS 1997 F350 7.5L is more reliable - although it rides like a Conastoga Wagon and rattles everywhere.

Is there a way to test the HPOP?? I would like to know what to ask the mechanic in the am? How would he know it was not just fittings? What would be tell tales that it was not the original pump? Thanks for the advice/info!

 

I believe you could take out the hpop,, throw it across the road,,, bounce it off the pavement,,, and reinstall it and it would be fine. Any shop that replaces a hpop on an 05 n up,,, Well,, I just shake my head. FYI,,,, I've got 771k on mine,,, the hpop is original.

I think it's another shop that knows how to sound like they know,,, But they don't. Not trying to be critical,,, I'm just sick of hearing customers tell me about how much they've spent,, And are still having issues. It's not the truck owners fault,, It's the shops that figure they can just "wing it" and do a proper repair.

 

Maybe we need a PDF printable page with Q n A's that owners can take with them to quiz the shop???

 

Maybe just a photo of various parts along with an answer sheet for the owner to grade them. Show it to the guy who is working on it and if he can't get them right, then you take your truck somewhere else.

Something like...

1. What can you tell me about these two parts? Do you have an idea where they might be installed on my truck?

 

To the portion highlighted in blue, MY POINT EXACTLY. I'll bet it was due to the STC fitting blowing out, causing it to hit the rear cover on the top right corner and cracking it to cause an external oil leak. To the portion highlighted in red, I CALL BS on that. In the yers wrenching on these engines I have NEVER seen head gasket failures cause an external fluid leak be it coolant or engine oil.

I shouldn't really be telling you this as a dealer tech myself, but I will. In the dealership world, we are discouraged frm "upselling" warranty issues. In other words, unless there is an issue with safety, we are NOT to bring anything to the attention of the customer. Having said that, I will from time to time point out something to the customer if I happen to like him/her, OFF THE RECORD. But if said customer is an absolute jerk to me, well too bad, so sad.

Ahhh the good old memories. I remember replacing countless exhaust manifolds (for warpage) and cylinder heads on those engines (for exhaust ports cracking right at the warped portion of the manifolds)

Two ways the HPOP can be tested. If during air testing the high pressure oil system reveals air exiting the oil filter housing and/or the turbo oil supply port, that is a sure way to condemn the HPOP. There are a set of block-off tools that can also be installed into the high pressure oil rails to isolate the high pressure oil system to only the HPOP and branch tube. Once blocked off, the engine can be cranked over to determine high pressure oil pump output by monitoring ICP volts/psi with a scan tool. This method is called "DEAD-HEADING" the HPOP.
