2017 gt350 engine failure

[Forgedwheeler]

Nobody is "bullying you".
I keep asking you to explain your thoughts as you keep saying it's something else. And you purposely avoid it.

I DON"T KNOW, and neither do you. My guess is the human factor is to blame.
There is good and bad in "hand built".

I drive my GT350 like I stole it. I keep it under the redline and service it myself.
If it breaks, I have a warranty. And I'm not one of those guys who seriously thinks this is an "investment quality" car. Ford's gonna make as many of them as they can sell, 20-25.000 at least. That will eliminate any collector value until long after there's any fuel left to put in them.

Good grief! Have fun with your Shelby. and stop worrying about matching numbers and all that other BS.

I'll say this. Many of you tech owners bitched about the lack of track time because of no coolers. That's more of a choice. Some "not all" buyers chose the tech pack knowing it didn't have coolers. They bitch and complain still to this day.
Who's mistake was this to offer a track car without coolers? Fords.
Who's choice was it to offer a "track car" with undesirable OPG material? Ford.
I bought a track pack knowing it had coolers and was meant to be raced.
If goobers engine blows from normal street driving how are we the owner not to be concerned of a engine failure while racing?
I accept everything the car is. Panel fitment, paint, quality assembly, etc. I don't complain about that. But a poor choice of material for a heart? You believe it.

I agree the tech pack was a shit decision and inexcusable. I've been very vocal about it.

His OPG likely failed and it sucks. He's one of the exoected R/1000 failures. I'm sorry to the owner, and hope his vehicle is out of the shop quickly. However even if he had a billet OPG, something else likely would've failed (head gasket, bearings not being properly lubricated, VCT system). This motor shouldn't be driven hard in the winter unless it's at temp, which takes awhile. He definitely still had a cold engine.

Where do you get this? Where did I run with a cold engine or cold oil? I never did that. Just because it was during the winter last year does not mean the temps were below 180

No I never hit the limiter.

Edit: thank you. You just proven my point. If the cold oil temps are the cause that would also point to the opg's being a weak link. I can get into my work truck any day. Any temp. Fire it up and drive down the road full throttle without issues of the opg's failing. Is it the right thing to do. No. But I'll bet they don't break also.

Some of the users here who drive their 350s during the winter report that the temperature during driving sometimes never hits 180... you need to block off the oil cooler duct to get it above 180.

You truck uses 5W50? Interesting. Because I'm pretty sure the 2.7 uses 5W30 which is almost half as viscous at cold weather as 5W50. Regardless, do that enough and it WILL fail. Do you not think so? The Voodoo will just fail quicker, and not just because of the OPG. Do you think any higher power motor is immune from that kind of abuse? Ford has a responsibility to design the engine well, but a driver has a responsibility not to floor it with a cold engine (BMW has a limiter just for that, which I wish Ford had) and not lug the engine around in 6th gear all the time.

This motor uses heavy oil. It's essentially a race motor on the street. Using it like a truck is going to fail your engine much quicker, I guarantee it. Is that right? No, it isn't. I wish this engine was much more durable. BUT... when warmed up and ready to go it is definitely worth the hassle of the special care needed and the OPG won't be an issue that more than 100 of us will face. Take a Trinity motor out in the cold and do the same thing, let me know how that goes. Or a LT4/LS9.

You said that the stock OPG is fine for occasional track and street use. I could make the same case for the MT82. It may not be the best, in terms of fast shifting and heat dissipation but its good enough. Gearing can be improved at the rear differential. How is one part good enough and the other isn't ? Racing transmissions are expensive. Billet gear is cheap, at least when done at the factory.

Exactly
Here's another thought. Fomoco built a flat plane crank and spent all this time, money and testing into the crank to help eliminate vibrations. Yeah some here said the bean counters control the build. Fomoco could of eliminated this all by using a 5.2 cpc that makes the same or more power, has less vibrations, and is more durable. Neither the FR350S nor the GT4 or the 5.2 crate engine use the fpc. The whole fpc was just a sales pitch. I would gladly give up my fpc for more of something else. The GT4 and FR350S use the cpc because it gives more Low end tq, vibrates less, is more durable and is proven to last. The cpc helps the car accelerate out of the turn and has more tq lower in the rpm. There is a reason why They don't use them in street and race engines.

This is NOT about matching numbers. Jesus Christ! You honestly believe I care about an original numbers matching car, or how original it is? Hell no! My cars not original now! Although it can be put back to 100% oem original no problem. I removed all the suspension and replaced all the stock original parts with new oem and modified them. I also highly doubt we'll see 20-25k gt350s. But if so, so be it.

Someone has to drop the bone. Come on you guys everyone is losing credibility as far as i am concerned, take the high road. Agree to disagree.

First off, my car was driven one winter day after I installed my headers.
2nd my car lives in a heated garage and I never get on it until it's fully warmed.
3rd I have more than one truck. I said work truck. Not my pick up. But to answer your question I have a 2011 f150 5.0 and a 2016 f150 2.7. I also have a 2013 transit connect and a 2013 fusion.
My work trucks are anything from 2011-2013 F150s 3.5 ecoboost, F550s 6.8 gas and 6.7 powerstroke, Freightliner m2 business class with Cummins isb 240 and 6.7 cummins. International durastars with maxxforce and John Deere 310k backhoes. Over 300 vehicles total. They get the living crap beat out of them daily. Running and idling 8-16 hours a day 5-7 days a week. 5-30 and 15-40 oil. In temps 90+ to as low as -10F. Never had a problem.

Ever run 15w40 in a gas engine during the winter months? 15w40 is thicker in cold temps then 5w50. Never had an engine fail running 15w40 in any season. Both oils are rated winter (w)
The (w) means winter, not weight.
The 5w50 flows enough at 40c much like a 5w30.
Were talking opg's pumping oil not concrete.
You are proving my points.

Based on your mods why even get a gt350 the cosmetics?

I love the looks, sound, performance etc. same as everyone else. My mods are minor. Nothing I've done is that radical.

Is this a video of the oil pump in question operating?

It sure is. No wonder it's so fragile, look at all that glass...:headbonk:

Stop dancing around what I'm saying. The stock vibrations are an issue, but in this case aren't the primary cause for failure of an OPG. Torque is. That's why we rarely hear of stock Coyote's failing their OPG (unless they bounce off rev limiter). Upgraded vehicles, typically supercharged, have this issue.

If you're stock, there are way more things that will likely cause an engine failure. Machining bits from the components not being thoroughly cleaned, cleanliness problems with hand assembly, wiring vibration (this engine is constantly vibrating, right? Wiggle a wiring harness for long periods of time and let me know how that goes), the OFA and lines disaster.

EDIT: Of course, I'd love billet gears. If I was building a track rat car, it would have billet gears. Occasional track use and street driving? Isn't necessary. Good forged PM is fine, everything else is scare tactics.

I'm not dancing around anything, I honestly tried to make it as simple as possible. If bouncing off the rev limiter (which, I think the vast majority of us have done) will damage the OPG then that isn't good news either.

The other things you mention are a lot harder to control and are a part of any failure rate of any engine, especially if QC is lax. Choosing which part to start with to reduce weak/failure spots is 100% controllable.

All I was trying to say is that most of us paid 59k plus and up for our cars. I'm willing to bet nearly 100% of us would've paid 59.5k and up for them to have the upgraded OPG.

I'm actually really surprised the R's don't have it. I can sort of/kind of understand (not really) putting what we have in the regular GT350s, but not upgrading it for the R is truly unacceptable IMO.

I am glad the R has the same opg as then non R, if it was different I'd be more paranoid lol

And it would not make any sense to have two different engines.

I didnt realize how much this thread has exploded, yikes!

 

[Screamer]

. Did ford put powdered metal opg's on the gt500?

Yes they were powder metal as were all the 4.6 / 5.4 modulars except the '05 Ford GT

just to add to your post:


In a 10w-40 for example the 10w bit (W = winter, not weight or watt or anything else for that matter) simply means that the oil must have a certain maximum viscosity/flow at low temperature. The lower the "W" number the better the oil's cold temperature/cold start performance.

Having a different OPG would make it a different engine? :shrug:

The R has many other upgraded parts for track duty, why not the OPG?
