For about three or four months now I've been hearing a clicking noise
from the engine of my 2000 Accord (4 cyl; EX) whenever I accelerate the
vehicle. The noise is not loud, but I can reproduce pretty reliably
every time the car is under high load, e.g. AC on, hot weather,
accelerating up a hill. It happens around 3000 rpm or higher, and as
soon as the car shifts up, the noise is gone, only to happen again when
I reach 3000 rpm again.
I took it to the dealer who replaced the spark plugs, telling me that
they needed to be platinum and the ones in there were not. The
transmission also seems ok. One other honda dealer I talked to in town
said that I might need a valve adjustment. He said these cars needed
one at every 30k miles. I have about 66k on my car, and I don't think I
got a valve adjustment at the 60k service (I did not have it done at a
dealer), if ever I needed one.
I have searched through this forum, and I have seen both answers, i.e.
that this model does not need a valve adjustment until 105k+, and that
it needs valve adjustment every 30k.
Can anyone tell me if its necessary? Or if the problem is something
else? The dealer said it would cost me $100. The other dealer told me
to bring the car back when the noise is louder (he couldn't hear it on
the road or reproduce it in the shop).
