Default Re: valve noise or pinging noise?

ok, i let the car sit for hours then i went and started it up and took it
for a drive. turns out it didnt make a single sound the first ten minutes,
when the car warmed up it started pinging . i say pinging because i know
that pinging is caused by hot spots and it makes sense that it would get
worse as the engine got warmer and you cant hear it at all when the engine
is cold or warm.
No i never used a timing light because i dont have one, i figured if i got
the mechanical timing right nothing would change. I also figure the engine
is running to0 strong and smooth to have a valve problem and i think valves
sound worse when the engine is cold anyway. i will retard the timing
tomorrow by ear until i get a timing light, i really dont have to drive much
this week anyway.
I guess im very very lucky to have no valve damage . i read that only 25
percent of honda timing belt breaks end up with no damage. from now on im
never going to let a timing belt go past 60k and i will check my belt every
10k.

i believe i didnt get bent valves due to the fact that my belt didnt
actually break, instead a few teeth on the belt just came off. there was a
six inche strip on the belt with no teeth. also, there was a lot of oil and
grime in the bottom of the timing belt cover, i believe that the belt
slipped enough to shut off the engine but not enough to cause the pistons to
crash into valves. the belt that i took out was honda oem, that's probably
why.
i should have bought a honda oem but i dont think i will have this car when
it hits 290k. it has 230k on it now and it looks great and runs great.
