My luck with the Mustang continues. Friday, on my way to work I'm heading up the freeway onramp and hear a noise. Car continues to run normally with no apparent issues. Boost is ok, temps are ok, no smoke, engine is smooth. I get to work and smell that sweet coolant smell. As I lift the hood, there's a slight hint of steam and a good puddle of coolant forming from the block near the turbo. My coolant reservoir is half gone at this point.
I head over to AutoNation Ford in Tustin. It's less than a mile from work I can't risk getting to the Ford dealer closer to home with that leak. At the end of Friday, they were unable to find the source of the leak in the obvious places, and since there's no oil, smoke, or abnormal tailpipe emissions, we're confident the oil/coolant barriers have not been breached.
Saturday afternoon, they said they found the leak. Somehow the block cracked, on the passenger side not far from the turbo. This kind of a crack would not have been caused by anything else I've seen online, and definitely NOT related to other EB failures people have had recently. The car has about 7,800 miles on the clock. :tsk:
The dealer's conclusion is that there may have been a (very rare) defect in casting on my block. They're ordering an entire new engine on Monday, pending Ford's write-off. I'm sure shortly after my engine will be on its way back to Dearborn (or more likely Allen Park) for Ford to dissect and figure out what went wrong. This type of failure is very rare, and I haven't found any prior case like this with the 2.3L engine.
This type can't really be attributed to 'first year' or 'second year' problems, since the block itself isn't new. It's been used for the 2.0L EcoBoost and various Mazda engines (it's a derivative of the Mazda L engine) since 2001. :shrug:
Meanwhile, I've got a rental... a 2016 F-150 XLT 4x4 Quad Cab with the big 3.5L EcoBoost. It's a fun truck for sure. But damn, my car has to be cursed. :frusty:
TL;DR: Block cracked in a fluke defect, allowing coolant to leak profusely. Engine internals are OK, dealer is ordering a new engine.
Lastly, please do NOT attribute this to ANY OTHER problems people have had with this engine reported here. This is a completely different failure and has nothing to do with the others. The last thing we all need is some stupid "EcoBoom" thread of bullshittery.
