Hi all

I have a 2002 CR-V 2.0 ES.
At about 5000 kms a clicking engine noise started. Now at 20.000 kms the
noise has increased to a knocking sound (that follows the revs). Worst with
cold engine but it never disappears totally.

What could it be - a piston thats too small? (I dont think a valve could
make so much noise but Im not sure).
Enyone else with this problem?

Thanks
Henrik
