Oil pump gears and AC issues.

[stanglife]

A single documented case.

I'm not saying the problem isn't there, but I wouldn't touch it unless it's out of warranty

Yep - and even ones where a damaged OPG is observed - there would need to be further forensic investigation to determine if the OPG was the cause of the failure of if another failure might have caused the OPG to fail....

Hi guys. I thought I would share with you what I have learned from working on my 2016 GT 350. I changed my oil filter housing to the canister type and while I had the parts off of the front of the engine I read about a few more failures on this site. I decided to change the oil pump gears too. I know it's been said that you can't get the oil pump off of the crank without separating the engine from the k member but that is not true, there is enough room just by dropping the oil pan. The biggest concern I had was being very careful not to damage the oil pan gasket and getting it sealed back up afterwards. Here is a picture with the pan dropped and front cover off so you can see the pickup tube does come out of pump to allow the pump too be pulled off of the crankshaft.

Can you get the oil pan out to replace the gasket with the k member in place?

Thanks
Jack

No, you can't get the oil pan out. You can only drop it about an inch and a half. I know that very few will be interested in doing this, just thought I would share some information if anyone was. My car is different because I bought it used and bought it pretty cheap because it was a hurricane Harvey car with no warranty from Ford. Since I did the work myself, I thought about $400 and a weekends work was worth it for the piece of mind.

The chicken or the egg approach......

Damn hummingbird engine.

Yes yes, it's about Coyotes but the same concept applies.

Did they actually confirm the fact that it was your OPG?

I guess not yet, but I'll let you guys know Monday. The service manager said that it's PROBABLY that.

They will never officially confirm that. If they do, ask for a copy of the report.

Will do. Why do you say they would never confirm that though?

I would suspect lawyers? Everyone who has had an engine replacement could never get an official cause of the problem. I dont think you will either.

My OPG just failed and I never rev high until the engine oil temp is showing 180 or higher. Take that for what it’s worth.

To say that your OPG have failed is a little premature at this point.....

I can't think of a single instance where anyone has gotten confirmation of an OPG failure. You turn it over to Ford and they don't tell you anything except that the motor was replaced.

I sure wish we could view some of those internal reports

Tom, I completely agree.

As soon as a Ford rep. determines the cause of a catastrophic engine failure..... they simply instruct the service advisor and the tech. to replace an entire engine. The cause of a failed component is often hidden.....

OPG upgrade is often associated with the use of Forced Induction..... Otherwise, I really do not see a pattern here with a N/A engine shattering the OPG. However, there might be a few isolated cases.....
If anything, I can see a more likely failure such as a spun bearing....... in the case of ’MulhollandMonster’.

I haven't heard of any proven OPG failures, but on the other hand, I did experience the AC failure first hand.

You’re absolutely right. While A/C failures are fairly common .... OPG failures are not.

Yes, you are correct. Ford (smartly) is not saying anything about the causes of failures. My 17 suffered a catastrophic failure the first time tracking last year. Ford does not let the dealer do any investigation other than dropping the oil pan to see if there is debris (mine had two broken rods at the bottom of the pan!). After the failure, we checked the oil right away, and there was enough oil. However, right before the failure happened I immediately lost oil pressure. My own deduction (as well as the dealer's thesis) was that it was the oil pump failing but again this is just using process of elimination.

It totally makes sense that Ford asks the dealers to not muck with the engine and ship it back to Ford, who sends a new one back for replacement. Much easier to deal with problems one by one then to reveal everything and fuel more speculation and open the company to liability, especially if a defect doesn't show up that often. So far, it looks like Ford has been pretty good about honoring the warranty, so long as the car isn't modded.

These seem to be the two most consistent failures of this otherwise fantastic car. Do either of these gremlins give you concern or do you just keep your fingers crossed? It sounds like there should be a recall for these two items.

You should avoid these cars like the plague, they are absolute crap.

Some people's cars can't drive around the block without going into limp mode, others burn quarts of oil every 500 miles, the rear bumpers sag and fall off, and if you do work up the nerve to get on it the oil pump will grenade your engine and Ford will deny your warranty for racing.

For the love of God, Montresor! Stick with your BMW or Porsche.

The problem on OPG failures is it's difficult to know whether the OPG failed first, or if something else happened which led to the OPG failure. Just because your engine ended up with a damaged OPG doesn't mean that the OPG was the cause of the failure or that a stronger OPG would have prevented engine failure.

Very true. There's a lot of stuff that's all directly connected to each other in the short block. Was it a blown piston? Or did a ring give up and shatter the skirt? Did the OPG fail? Or is there a crack in the balancer that sent a bad harmonic through the bottom end and killed the OPG? Was it a bearing or an idiot driver that baked the beans while the oil temp was at 90 degrees? Etc etc etc.

21,000 miles on my car in 17 months of ownership including winter. Daily driver. Its driven every single morning even when it was -20F outside with wind chill. Lots of days where oil temp never goes above 165 even after an hour of driving (this is with taping all the front grills with the exception of small opening).

No issues with the engine or OPG whatsoever. Did an oil change after the cold, lab results are spotless. Oil consumption is actually lower now (2000 miles per 1 qt vs 1250 miles before).

AC did fail in 6000 mile mark but it has been fine since.

This is actually THE most trouble free car I have ever owned. In 21,000 miles, car went to service just once and that was AC. All my other cars, all BMW M cars before, which i thought were trouble free, would go to the service for small issues every few months like cigarette lighter port going bad, windows not working, trunk springs going bad, etc. I never had major issues with those M cars and I drove them hard but they would still have things broken here and there. GT350 on the other hand is bullet proof.

It sits in my garage now covered with probably several microns thick road salt
