Re: Timing Chain Rattle Remains!!!!!!!!
how they function? not very well on the EAs! the major problem (o-ring being sucked into oil pressure passage) was fixed with the 4.0 engine. they have a spring that hold the chain tensioned before the oil pressure builds.. it doesnt do a real good job though so they usually rattle for the first few seconds on startup. perhaps the oil pressure passage in the block is choked six_in_a_row.
