Yes, what Big3 pointed out:
Engine tick. A slew of 1998-2004 3.2L and 3.5L Chryslers (build date prior to 3/31/03) may produce a ticking sound from underneath one or both valve covers. Chrysler says the noise usually occurs on cold startup, lasts for only a few seconds and is most likely due to excess slop between the cam and exhaust rocker arms. Replacing the swivel pads and swivel pad retainers on all the exhaust rockers with updated parts from a kit (Part No. 05135237aa) should eliminate the racket.
Vehicles that are prone to the noise and can benefit from the upgraded valvetrain parts are 1998-2004 LH-cars (30OM, Concorde, Intrepid, LHS), 1999-2002 Prowlers and 2004 Pacificas.
