Guest FBody Addict Posted July 29, 2004 Report Share Posted July 29, 2004 Girlfriend has a 99 cav with the 2.2l L4 engine and i am trying to figure out if it is OHV or SOHC and trying to figure out if a ticking noise is valves in need of adjustment or what Quote Link to comment Share on other sites More sharing options...
SVTCobraGuy Posted July 29, 2004 Report Share Posted July 29, 2004 Crap, MSN Autos just says "OHV". I usually lookup stuff there. Most newer cars use engine oil (hydraulic) valve lash adjustment. I know some of my previous cars had a slight tick that came with age. Cars running hot got also get a valve tick sometimes. Mechanic's stethoscope (Autozone - $10) might help you pinpoint a noise. Maybe try a little thicker oil for the summer? Hope this is of at least some help. Quote Link to comment Share on other sites More sharing options...
