Sounds like one of the lifters is not happy. How old is the oil? Is the level within the hash marks on the dipstick? I have an old beater four cylinder that makes the exact same lifter chatter noises if the oil gets too low or the oil is past due for changing.

A lower pitch click could be from the cams snapping over center due to slack in a secondary timing chain. There must be at least 10 psi of oil pressure to keep the chain tensioned.
The same sound could also be caused by a leaky check valve in a chain tensioner. Try to identify the source as from the left or right bank. The retainer for the check ball could be loose. If so, the tensioner can be repaired rather then replaced. |

The light for the airbag on my 1990 z, and the seatbelt light on the dash come on while driveing the car. Never has done that before. Unpluged the battery to see if that would reset the computer. Lights are still on after hooking up the battery. Any ideas what could be the problem? Thanks in advance, zr1dave@hotmail.com
