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

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.

Straight from the National Highway Traffic & Safety administration. This problem has been around for a while, and affects 2.2L S10s, Cavaliers, Sunfires, etc. I hear them every day.

Dealer says this noise is normal, however can be corrected by using an updated timing chain
