Hey Rob,

Just wanting some more info about the Hydraulic Lash Adjusters...I have them on my truck and and everything from the head up is new but it rattles like crazy when right after it starts then goes away until i go above 3000rpms...what gives? Ive read something about neg. pressure but what do I need to do to fix it? Ive replaced them but they still do it

Thanks J-cub R ( talk) 23:07, 19 June 2009 (UTC) reply
