Tappet Clatter?
 

I have a new 2003 CR-V.
After driving in the hot climate of Southern Arizona,
so the engine is fully warmed up,
if I stop the engine for a half hour or so,
and then restart, I hear what I think is tappet clatter which stops
after a few seconds.

I assume this engine has hydraulic tappets and they are bleeding down
while the engine is shut off. I don't think they should bleed down in
a half hour.

Anyone else?
Comments appreciated.

I think that all Honda engines have solid lifters, hence the 'need' to
adjust them periodically. The noise is probably from the oil pressure
rebuilding after start. Shouldn't last longer than one second though.

I seem to recall reading that this is a normal sound that you don't have
to worry about--just get used to it. Eventually, you will probably not
even notice it.
