Noisy Hydraulic Tappets can be cured by simply pouring RESTORE into the normal engine oil.  If you have worn valve guides and cam bushings and cam lobes we recommend removing the rocker cover (also called the valve cover) and pouring a few drops of RESTORE directly onto each moving component (you need to get the RESTORE onto the valve stems i.e. through the springs) and cam wear surfaces.  An old plastic syringe works well (don't use it for anything else afterwards of course).  This normally takes care of valve guide problems.  RESTORE will not be able to rebuild a cam lobe that has been ground away by low oil levels though.  You may need to add shims if the cam lobes have been ground away by a low oil situation, or change the camshaft.

Rattle that starts at 3000rpm - suspect low oil having caused hydraulic tappet damage and subsequent  rattle noise  try some RESTORE and make sure to keep the oil level at the top of the dipstick. If the oil level drops the rattle will return at 3000rpm or 60 mph..
