Is this any cause for concern? Cannot hear the ticking sound with the doors closed. Car drives fine.

 

does it increase if you rev the engine a little? I'd guess a bit of a noisy lifter. They are self adjusting so if they get a little crud in there they may not come up to full oil pressure and they tend to tap a bit.
Not a concern if so, but you can run some engine cleaner thru it right before your next oil change, often cleans it out. a can of Sea Foam is what I've used.

 

There are no lifters in the AJ33. The bucket rides directly on the valve stem, a shim sets the clearance and the cam directly contacts the bucket. The clearance is manually set. There are no self-adjusting hydraulic mechanisms.

 

Well thanks David, I was under the impression it had hydraulic lifters. Learn something new each...

 

i was reading one thread about this where the symptoms were pointing to the purge valve. I just replaced the PCV valve , and have a new purge vale. cant seem to locate this. can somebody please point me in the direction? my tapping sound does not sound engine related , but as one of the members said , can hear it in the lower left dash when idling. its PM# IJG151BB

thanks
