so my z is having overheating issues. now my uncle and my dad think its a blown head gasket so did i but i dont have loss of power smoke isnt coming of my exhaust theres no coolant leaking everywhere. this means something else is the issue i bled the air out of the system. i drove around for a bit and stopped to look under the hood. im hearing a sound from the passenger side of my engine like escaping air and its not from the air relief valve i tightened it pretty well so im thinkin that my head gasket is messed up what do u guys think

 

Check to see if the radiator cap has the complete rubber gasket, my rubber piece on my radiator cap tore and was doing the same

 

If you hear escaping air. Its probably escaping air. Id look into any rubber hoses that hold air or very hot fluids.

 

^^^^^^^^^^^^The bleed valve is on the passenger side - you might start there. And bleeding can be a biatch some times - I know some pretty techie 350 folks who had to do it 2 or 3 times.

 

op, you have multiple shops in the city who specialize in our car.... why not bring it to intense or conceptz or 350z motorsports? ( havent checked on 350 to see if theyr are still biz in awhile tho).

or..... just take it to a dealership or any Brakemaster... no guessing please..cmon now.

 

ok so it turned out it was just air in the system i didnt really realize how much of a pain it was to bleed it out until well i let it run for a good hour with the cap off and now its fine
