Ticking at idle

It is entirely normal for valve clearance to increase when the temperature is in single digits. The book calls for clearances to aset at less than 100 F (38C). It doesn't say but we were always instructed that the temp should not be less than 68 F (20C). Obviously, if the temperature of the valve system is less than 68F the clearance increases enough to hear tapping. However, that ta[pping should go away as the engine comes to operating temperature. The longer that takes the longer the tapping. As long as you don't thrash the engine you're OK. Thr reason for setting at 68 to 100F is because that insures the proper clearances at the realoperating valve train temp - somewhere in the 200 to 280 f range.
Out of curiosity, Suzuki has automatic valve clearances by an innovative floating bucket system so valve adjustment is unnessary even though the 1300 will rev to 13,000 rpm.. Wonder why Honda doesn;'t do that.

Yes, the Suzuki valves are hydraulic just not quite the same parts as Detroit's. When hydraulic valves leak, Oldsmobile or Suzuki, the clearance increases and you get valve rapping.

Sorry to bump this but it's related. My 08 had 96xxx mi and had been ticking for some time. It also had an off-idle, small hesitation that felt a little like clutch slip. I had the valves adjusted and the ticking and the hesitation went away. Now, with 99xxx mi and the ticking is as bad as ever though the hesitation isn't. Valves out again or something else? TIA
Edit: I should add that the car runs fine and still gets its usual gas mileage, 36-37 mpg. It has started using a bit of oil, maybe a quart between OCIs.

.So not being an idiot, I'll take the car home and use a block stethoscope to see if I can pinpoint the location of the ticking. BTW, I rarely exceed even 4000 rpm.

I probably pass 4k rpm almost every time I run through 1st gear. So like a dozen times a day at least. Granted it's often gradual or linear acceleration, and not launching it all the time. This is a Honda, they want to wind out to red line every so often.

I'll report back on the ticking when I have more info for anyone that cares.

The Fit is my DD also. My other car is a 2.0L meth junky with a 65lb/min turbo hanging off it.
