1990 626 with a single valve knock.
Do the valve's have adjustable lash or hydrolic with shims only?
If adjustable what is the gap set to?

they are HLAs
perhaps you have a bent valve?

Thanks TheMan, will crack open the cover and take a look. With 150K+ miles and a little oil burning I suspect the rocker arm is shot and out of round at shaft or a bad valve spring.
