I am considering upgrading my oil pump. Do any of you know how many hours it calls for? I am considering this as a preventative measure. I also have no warranty. I have a lift, tools, and talent to perform the swap with no issues, I was just curious about whats involved on this platform.

Here's my point.
Forged what's to say it's not the OPG because they tested it. But he also said he believes it's something else that is causing the opg's failure. I'm asking him or anyone else to explain what that maybe that causes the opg's failure and yet you or forged cannot. All you two keep saying is it's something else. But yet you say you still want to change the opg's after your cars out of warranty. With a statement like that, you don't trust the opg's yourself.
I am NOT saying all opg's will fail. I'm not saying another one will fail. I'm saying it's a poor choice in engineering to use powdered metal.
I am not angry in any way towards you or anyone. But I am disappointed in ford for making the choice to use an inferior material when it comes to the heart of the engine. Yes I get engineering. Yes I get bean counters. But I do not agree with you in the cost aspect between powdered and billet opg's.

Until your engine goes south, you won't care. If it does blow you'll be upset. Especially when the dealer gets ahold of the car and does something else to it.
You're absolutely right in regards to me not offering an explanation in regards to other possible causes. Firstly, because mechanical engineering is not my field, nor have I direct experience in engine design. My only point being, is that without being able to tear down each of those engines, you cannot say that it is 100% the root cause of the failure. We aren't offering "this is what happened" because to say so is foolish, because we don't know without all of the details. Certainly does appear to be the OPG in many of these cases, I don't deny that one bit, but has it been proven? No, so to take those as "facts" WOULD be a bad engineering choice, as you base decisions off of speculation rather than cold hard proof that we don't have.

You can say it is a poor engineering choice, but when something fails within the tolerable range, how do you justify your statement? Based on your personal item wish list for the engine? That is not engineering design based, but rather a "nothing but the best" mindset, and therefore everything else seems inferior or is a "bad design", even if it only fails 1% of the time for arguments sake.

It has nothing to do with me not trusting it or not caring. I absolutely care about the potential issue, and like you, much prefer having each part be the best it can be to increase long term reliability. But you mistake me, as I am simply running the numbers myself. I know that the chances of a failure must be VERY small, and considering how expensive it would be to replace an engine on my own dime, it does not make any financial sense for any of us with stock vehicles to tamper with it prior to the warranty expiring. I will happily play the numbers game over the next 3 summers, at which point I will replace them outside of warranty for additional insurance. I can guarantee you, that from a financial standpoint, my stance is of the far greater value while any of these vehicles retain their OEM warranties.

As long as they can prove that their parts meet their required reliability, they will never change them. I just wish they would get a move on with a KNOWN issue that is the dam cooler hoses... they got 3 months until my car is taken out of storage, if they don't have it ready by then, I'm going to freak :lol: :D

Sounds like "the tolerable range" is the problem.

I'm no mechanical engineer either but I would assume what works for an engine that redlines at 7500rpm and has significantly less vibration probably isn't going to last as long on an engine that revs to 8250rpm redline and has so much vibration that it needs counterweights on the transmission.

I am an engineer. I work with exotic forged materials all the time.
What concerns me is the automatic assumption that powdered metal is inferior.
These sintered, heat treated parts are a mix of alloys with properties specifically chosen for the purpose at hand. There are literally millions of performance engines in service with PM connecting rods. They are chosen because they are strong as hell and have no internal stresses from the machining process. The PM manufacturing processes are also extremely accurate and absolutely repeatable.
Making billet parts is a much slower, less exact process. I don't argue that 4130 chrome moly tool steel is stronger. But these PM production parts are designed to be as strong as they have to be. Thousands of hours of testing and metallurgical analysis goes into these decisions.
PM is often chosen for these projects because oil pumps work best when very close tolerances are held, and no machining stresses are induced.
To hold very close tolerances with machined parts is very expensive by comparison.
As an example, the Voodoo engine oil pump produces 35-50 psi at IDLE with hot oil. That requires a pump with very close tolerances. My guess is that the Ford engineers spec'd out the performance criteria for the pump and the vendor met a price and performance standard. You can bet your ass that lots of testing was done. Billet gears that perform the same might literally cost 10 times as much.
I agree that a billet pump would be better. No question. It is possible that defective pumps are causing engine failures. My final point is that Ford will analyze the failures and decide what to do. If the pumps are too weak, we will know soon enough. Until then, everyone is ill advised to tamper with these engines. Ford will cancel your warranty in the blink of an eye. And you will have no recourse.
BTW, I bought an extended warranty for my car and I'm just not going to worry about it. The car is just too much fun!!!!

Good point, and that certainly could be the issue. But that right there is where the bean counters say "ehhh maybe we'll lower our expectations in this instance because it saves money" if its nothing drastic, who knows.

Agreed, I am a civil engineer so concrete, formwork and rebar are more my expertise, but I understand the processes that the mechanical guys take when designing these things.

If it is deemed that there is some flaw, which in reality could more than likely result from errors in the assembly rather than design, we will know. Personally don't think we will ever see a recall for this part, and based on the typical knowledge/experience levels of the Ford Techs, I actually hope we don't see a recall! Would rather take my chances over the next 3 years than have a dealership perform a fairly technical replacement and possibly destroy the car :lol:

You're most likely looking at less than 1.5-2% MAX for total failures before a recall gets issued. We've seen a few on here yes, but again, we are ASSUMING that it is 100% the OPG's that are causing the failures. Chances of several hundred engines popping directly because of the OPG's? Chances are probably very, very small.
OK, so that is from what? How many engines are built or how many cars that are built? Who's doing the investigation on OUR part of whats being destroyed? Are we supposed to TRUST that we're getting the truth when there is a large amount of money on the table for ford to be open and honest? IF its not lawsuits out the wazzooo, I don't trust them. This OPG or whatever is destroying our engines, isn't gonna kill us (most likely) but we sure got notice about the oil lines and there are less of those instances reported on here than destroyed engines. I have no doubt in my mind there will be more than 1.5% of these engines being destroyed of the 18000 that will be made. haha, maybe thats why ford is building them an additional year, to hopefully offset the defected engines to keep it below the 1.5%. Maybe they will keep a better eye on the builds...or demand better QC from the suppliers.

Ok people. I know this is not rocket science and that this is not a way to test the durability of a OPG as it works on the engine. But it proves how weak the powdered metal OPG is when dropped on a Concrete floor for. Height of less then 4 feet. I did two drops. The first you'll notice a ring in the steel as it hits the floor. The second drop you'll notice a thud when it hits the floor. The first drop fractured the thin wall of the OPG. A steel billet gear would not break this easy. Again I realize this is not a proper test. Just pointing out how weak the metal is.

I am absolutely certain that a drop test onto a concrete floor is not part of the oil pump testing protocol. BTW, "Weak" is not a technical term.
I know you are convinced that the PM gear is inadequate. Nothing will change that. So I am going to stop trying.
Take Ford to court. Try to prove this part is inferior..
Any army of lawyers and engineers will show you what great parts that you can make from powdered metal.

Guys, its a super secrete project we're working on...
Sign this confidentiality agreement please.
OK, He're what we're gonna do. We're gonna build a 8250RPM engine with a flat plane crank. Its gonna have 520+ HP and be a 5.2 L. Its gonna vibrate to high heaven so we're gonna need to balance it correctly. Alright... so, lets built this thing stout. No question were going to need Forged pistons and by all means lets use the toughest oil pump gears we can, powdered metal so that our engines last the test of time. Lets get to work fellas!

Ford has a warranty on the engine. They will honor it. That is 100% of their obligation under law, unless you can prove they knew the pumps would fail in advance. Good luck with that.
I'm not even a little bit convinced that the pumps are the problem. I think Ford will find that assembly errors are the culprit and the pumps are just consequential damage.
My two cents. My opinion is just as valid as all the other spewing vitriol on this forum. Right now, its all conjecture and anecdotes.

So, in your opinion, how are we, as a consumer supposed to find out what is wrong with the engines, under warranty, when they are boxed up and shipped back to ford? Do you TRUST that ford is going to tell us? Is there an external investigative committee for such things? Who's to say they aren't "paid off" to keep it hush? I'm just sayin... if we don't hear anything, doesn't mean there isn't anything specific going on. There very well could be, they know it but don't tell us. Most people/businesses want to make money, not lose a shitload of it, and the repercussions could be ESPECIALLY bad, from the performance base, trickling down to the everyday car. Its already happening in a small dose from the oil line recall. Ain't too rush rush about that.
Maybe they are just debating on having a massive recall for what is destroying the engines and the oil lines to get it done all in one swipe HAHA....
I hate to be such a downer about this shit, but even the 1984 yugo had less engine issues. Just for a estimate...there were a zillion of those made and I didn't see a one of them on the road 2 years after they were done production.

You're becoming annoying. I'm not looking to sue ford or talk you into anything. Better parts can be made of steel also.
I clearly asked you to tell me what part you think is causing the failure and you have yet to post your thoughts. According to you they test everything. I agree they do. So if you think it's something else then please share your thoughts. Because let's say it's a valve spring, bearing, retainer etc working its way into the OPG that's a failed. Are those parts not made of the proper material also that's been tested and possibly failed? See my point.
I agree I'm speculating. But with the history of failed opg's and what causes them it makes perfect sense.

They have absolutely, positively no obligation to tell us anything. You can sue them, but you have to demonstrate a cause of action. If they fix or replace your engine, they are following the agreement they made with you when you bought the car.
You can allege "diminution of value", because the engine was replaced, but you have to prove the damages. Very tough hill to climb.

I don't know the cause. I'm not inclined to speculate. But I HIGHLY doubt that Ford green lighted a defective, or inadequate pump for this engine. Possible, sure. Probable? No way.
I will quickly admit my error if I am proved wrong.
