Just in case anyone asks, i did search, and am certain HLA noise is what i think, just need some reassurance (Daily driver = Fix on weekend = limited time to repair) 

Well, yes, that is hydraulic lifter noise, might be some more noises in there as well. How long has it been like that? Just buy it, suddenly develop?

 

You going to dive in and do what ? I would check oil level, oil pressure, oil quality, oil supply and pot compression  first before diving in to replace them with new or reco HVLA's

classic lifter tick. not a non-sale by any means.

Thanks fellas, this isn't my first rodeo by any means, but when it comes to an internal noise i have never trusted my gut, as for the oil and pressure and what not, the oil is fresh along with a bosch filter, up to proper lever and running about 40 lbs at an idle warm.  I did replace 6 of the 8 HVLA's when i pulled the engine for top end overhaul, so maybe one of the two that did test good might be on the blink.  Ill update when i decide to dive in (dive in I.E remove cam towers and check, file and massage where needed)
