2.5 L Atkinson motor Hybrid has Solid Lifters.

[Red Eyes - Wide Shut]

Be aware of this when you buy the Hybrid. At some point the lifters may need replacement if there is a problem. There is no adjustment. A super expensive cost due to tear down.

Called , Direct-Acting Mechanical Bucket Lifters. (DAMB) For damn expensive! Had I known at the time of purchase I would have passed. What about you?

The 2.5 drivetrain is extremely reliable and this knowledge does nothing my happiness with my Maverick.

Sell yours now while it still has value and get into a vehicle that you’re comfortable with.

Most 2.5's last 400k-600k miles. It's a non issue.

Well, hopefully consistent and timely oil changes will help. If you don't do that, it is a recipe for disaster and shorter life anyway. It kind of really surprised me when I found out. I've learned now to look much harder and deeper at a new vehicle before purchase. I am looking at getting my wife a Hybrid. I've gone through all the SUV options and Toyota is the number one hybrid system hands down. Ford copied and Mazda put the whole drivetrain in there new model. The Honda CRV and KIA use a terrible set up and don't have a hug improvement on mileage. Although our last 3 SUV's have been the CRV which never dies and is super reliable with a high resale. Maybe I've got the jitters because of the massive amounts of recalls and well known quality issues with Ford. It's been 40 plus years since I purchased a Ford truck due to the failure and short life of that one. Have had many trucks and still have a full size.

The Sky is Falling. Hand wringing over that and also the carbon buildup on the EB is ridiculous. With proper maintenance of todays modern engines, several hundred thousand miles without issue is common. If you scared or worried, there's options out there that you could trade it in on that "might" be a better fit for you.

Carbon Buildup on the EB shouldn't be an issue on the 25 and up.

Ford did not copy Toyota. They codeveloped various parts of the hybrid system together and then split off for the rest.

Can you link to any examples of the Ford Duratec 2.5L Atkinson experiencing failure due to the solid lifter design? Or is this just something you’ve decided to worry about and dread when no issue exists?

The 2.5 uses a "shim and bucket" valve train. Nothing to worry about in my opinion. Very reliable. I had a 650cc inline 4 Yamaha back in 1980 that had the same set up. Easy to adjust. I did it when I was 19. Pop the valve cover off, measure the clearance between the cam and shim (when valve is closed), put a thinner or thicker shim in to get the clearance correct. Ran the hell out of that Yamaha at the strip, no issues. Don't make a mountain out of a mole hill. You are worrying about a silly little thing that dont add up to nothing.

Phew, I thought you were gonna tell me it had hydraulic lifters that would leak and give it lifter tick after 150,000 miles.

Or solid lifters with an adjustment screw that you have to do every 60k or more often if they loosen up.

You've got 99 problems and solid lifters ain't one.

Shim/bucket drive trains have been around a long while. Had it on a '98 Tacoma 3.4L engine. That was a quiet engine and easy to check and correct clearances. The main cause of wear is oil change interval not adjusted for the way you use the vehicle.

Didn't even know this was a thing, certainly not on my radar as something that will matter. Realistically these are just regular old disposable vehicle that if they last 150-200K miles, maybe a bit more with vigilant maintenance + little or no road salt, they did their job. I have pretty high confidence the core of the powertrain will make it that long. All the vehicles these days with small displacement + turbocharging...way bigger question mark. Was just watching a car wizard video that popped up this morning with a 1.5L EB disaster.

Unlike Toyota's that have used them for years - it's not even in the maintenance schedule.

And the lifters aren't replaced - the bucket spacers are.
Well - unless you waited way too long listening to a terrible sound not checking things out.
But my guess if you do that - you are having bigger issues happen that truly are more expensive by ignoring them making noise too.

Yeah these new vehicles are all like that, even the Maverick. So many single use fasteners for no reason other than to rack up the bill for dealership profits. I feel bad for that BS owner.
