Strange Valve tick after scenic drive

[Jeff]

hmm sounds like you need new lifters.

RTFT

He doesnt have lifters.

Hmm yes he does. Trust me I know. His DOHC engine has lifters. The "rocker arms" in his engine pivot on the cam, and one end is on the vavle and the other is on the lifter.

RJ is referring to "lifters" in the traditional V8 pushrod sense. By this definition of lifters Justin's engine has no such thing. Now if you are talking to TurboDodge or Neon people he does. The reason being is Mopar (and thus most aftermarket companies) call the lash adjusters "lifters." The lifters in a DOHC or SOCH Chrysler engine are not lifters but hydraulic lash adjusters. So you are both right... The lash adjusters pump up with oil pressure and put resistance on the back side or the rocker to keep it in contact with the cam and the valve. If they see low oil pressure the spring inside them fails and that makes a terrific noise as the rocker arm bangs against the cam's roller surface, the valve, and the top of the "lifter."
