d series honda's used solid tensioners for years and years and they never had issues. i think the recommended replacement interval is around 160 000 km's or 100 000 miles in normal conditions.
D series Honda engines use a spring which constantly applies pressure to the belt.

The K's use a chain, and chains stretch at a constant, even rate with use. A belt should only stretch once, and only a little. Like I said, how many Hondas have you ever known to need the tensioner reset, ever?
But Honda still equips those engines with an automatic self-adjusting tensioner. I will admit I do not know how much or for how long a timing belt will stretch.

My OPINION is that no street or daily driven car should use a solid, non-self-adjusting tensioner.

Beat me to it. Its a spring, just like a 1.5L Mitsu. Love how simple it is.

Since it is a spring, it is also an auto tensioner!

for clarification...

the 1988 - 2001 Honda civic d-sieries (1.5L-1.7L) (and also similar year F-sieries 2.2L sohc) they did use the spring to help set the INITIAL tension on the belt. Once you tighten down the 14mm tensioner bolt it locks the eliptical tensioner in place. This is why they have a access hole in the lower timing cover to access the tensioner bolt so periodic re-tensions can take place (which are never done usually). So those tensioners are a solid one that does not adjust tension overtime unless someone accesses the timing cover plug and does it themselfs.

The 2002(3) + D's (till they changed to the K's and R's) civics used a different style tensioner which would allow the eliptical tensioner to still move even when the tensioner bolt was tightened down so the spring could account for stretch in the belt without needing adjustments.
