Great sound clip -- reminds me of the sound of my green and mighty 1974
Volvo 245 station wagon (a.k.a. The Zuke) sounded when a valve stem broke
and jammed and its pushrod bent. (Not really sure of the order of
things.) In my case, however, the clacking sound was very high energy and
I couldn't tolerate listening to it for more than a few seconds each of the
times I started the engine to try to troubleshoot. I can't tell from the
recording how harsh that "clack" sound is.
Before proceeding with Dennis' recommended valve cover removal, you can try
putting your hand on the valve covers while it is operating. You may find
a difference in one side that really convinces you about which way to go
first - ?
In my case, I believe the complete repair was about $100 (Vancouver Island
Dollars).
hope this helps,
gabby
