Just to add that “back in the day” valve lash adjustment was part of a routine tuneup along with distributor points, whatever they are, and applying grease to the grease nipples. My 69 VW van had valve covers that were held in by spring clips and were removable by hand without any tools, and had nothing blocking them. Then again, that was just a glorified lawnmower 😂Over the years, Hondas have received criticism for requiring more maintenance than other cars. Our 1990 Accord recommended valve-lash checks every 6,000 miles.
Can you imagine having to pay a shop twice a year? Neither could Consumer Reports.
So, around the late '90s, Honda decided to arbitrarily increase valve check intervals to 100,000 miles. In other markets, the recommendation was 30,000 miles.
Guess what? The B-series engines in Gen1 CR-Vs often suffered burned exhaust valves. Honda replaced MANY cylinder heads on warranty, most of them on goodwill.
I guess this anecdote emphasizes that Honda never thought that doing maintenance was a 'bad thing'. Some of the maintenance was dictated by unique design of the assemblies.

The RT4WD system was unique in that it didn't require locking clutches/differentials, yet was 95% as effective as those that did. Less weight, better fuel economy than other designs, too.
Driving on slippery surfaces, such as snowy roads, is safer and more secure if the engine’s power is conveyed to the road by all four tires, as even if the front tires slip, the rear tires can push the car forward.global.honda
Now, I have nothing against Porsches (owned one!) and I know that one time, Porsche was challenged to design components that were very robust, and they did it! Would have cost a significant amount more than the then-current prices. (Couldn't find that old article just now)
I have to change my frame of reference. To me my 99 CRV is modern…. 😂So 30ish years ago.. Honda had valve lash problems with their engines. That painful experience probably got factored into future engine designs though.... knowing Hondas historical penchant for continuous improvement in design.
Time to put the "way back machine" away here. The new engines don't really need valves adjusted now days.
In the modern era of maintenance and service, Hondas keep getting better in terms of the amount of maintenance required. However, when something in the vehicle does break, the cost to repair is higher and higher with all the high tech components. Cost to routinely maintain CRVs though is among the lowest in the industry. Of course labor costs keep going up, so it is amazing we can properly maintain a modern CRV at such low ongoing costs.
