I have a 1995 Nissan altma gxe when I start it the valves make a noise but after it runs for a while it stops
Sounds like an oil problem. Could be a failing oil pump, or plugged oil channels. Do an oil change and try using "high mileage oil". If you're using a different weight oil than Nissan recommends switch back to what Nissan recommends. That may do it as well. HTH. -Jim
