2.5 L Atkinson motor Hybrid has Solid Lifters.

[Cidecar2]

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?

Run Valvoline ultimate full synthetic. Check the oil bloa on here and you can see the zinc content. Flat tappet motors need zinc and lots of it!

I'm pretty close 60/40 other direction annoyingly.
Too flat in general.

It is really surprising how much rolling or mild hills helps. Sometimes it seems the Interstates are flattened too much for our benefit as the downhills are often too long as are the uphill sections. And, of course no slope at all just keeps the ICE running all the time at highway speeds. I favor rural roads around here when I can. It's not that flat around here and the Appalachian foothills are only 60 miles away. Currently showing about (from memory) 4350/9730.

A LOT of modern OHC vehicles have bucket lifters, especially 4 cylinders. They typically Never Need adjusting (replacing) unless there’s another problem. They literally last the life of the engine even if it’s more than 200,000 miles. Don’t worry about it.

 

[Darryl]

Yup, Ford and Toyota have been using it for years (probably decades?). Nothing new. I'm struggling to remember even a single case of a vehicle needing just a lifter adjustment. Yes a valve clearance job on a vehicle with buckets is a lot more involved than, say, a Honda with solid lifters but adjustment screws instead of buckets.

But realistically, the lifters shouldn't need adjustment unless something catastrophic is looming (like sludge from not changing the oil on time and excessive metal-on-metal contact because of that).

You are right. They typically NEVER need adjustment.

 

[Darryl]

It would be an issue if the hybrid saw a life on track, but thats about it. I remember the old Taurus SHO with the Yamaha 3.0 and 3.2. With how those were driven you definitely had to check valve clearance and shim as needed every 60k or so.

With modern oils especially I wouldn't sweat it.

Toyota, Mazda and Ford have been using this design for decades . When the engine finally wears out and gets tired, it's never the tappets.

Oh I dont disagree at all

Its amazing if you aim to get to speed right around the crest of the rolling hills and let off the throttle for a split second to enter electric only you can milk it for sometime.

EDIT: I'm currently in perfect time of year - no AC, no travel (currently), just city driving in a urban suburb that quickly turns to rolling hills. On pace for a 653 mile tank with a roughly 70% electric miles and 46mpg

I have never had an issue with lifters in any of my cars, all have pushed 150,00-200,000 miles. I don't think it will be an issue here either

 

[icegradner]

Many of those were recognized (probably because he's seen plenty) and pointed out.
I think he made a comment about single-use bolts too, but that may have been when working on a Toyota, because I'm sure he didn't recognize them by sight.

Yeah CCN goes into a lot of detail with his reviews. I suspect he looks at the service manuals as part of the process, since his knowledge goes far beyond the typical marketing notes that most reviews have.

Flat is still fine for gas mileage. You can "surge" on flat ground- speed up a little then 'coast' on electric. At 45mph or so I can get some really good gas mileage!

That's where the "pulse and glide" technique comes into play. I have so few flat areas that I regularly traverse that I almost forgot. I do use this method on long gradual uphill sections also.
Edit: After a while all these techniques come automatically without really thinking about them.

Another data point: Cummins B Series engines used to use solid lifters with inspection at 160K miles. Haven't got my Maverick yet, but solid lifters are a non issue. 37 Year Cummind Retiree.

I like driving the Ozarks/southern Missouri. The rolling hills work the battery/hybrid nicely.

I'm currently in perfect time of year - no AC

Around here we call that "January"
