Hi,I have a 2002 Nissan Altima. Cracked Head Gasket probably.

Asked by Asif Aug 21, 2015 at 01:56 AM about the 2002 Nissan Altima 2.5 SL

Question type: Maintenance & Repair

Hi,

I have a 2002 Nissan Altima and I was getting P0302. So I changed the plugs but the
code came back again. Changed coils and now it was giving me a P0300. Suspected a
cracked head gasket so took it to nissan and they said it was a cracked head gasket.

After about a month of still driving, the code went away by itself today. Car was not over
heating and no smokes were coming out. Coolant level is still almost the same and engine
oil still has it's brown look. Battery is a bad battery so could that be doing anything? Or is
nissan trying to get some money from me? Could really use your help here.
