Hi guys.
Thanks for input. Found at least 1 lifter malfunction and decided to change them all.
Went with CC high energi hydralic set. 1 start up and no sound. Cross my fingers it will stay that way.
Sell those old ones 'as is', some guys dont care if it rattles for a minute or 2 at startup...like me. Could also shim those hydros and make them solids.
