Ok here is my problem, my 1994 Z28 keeps losing antifreeez, not lots of it but i have to fill it every couple of days. Now it does not show any signs of a head gasket being blown (i.e. white smoke, antifreez from the tailpipe, mileshake looking oil, a guy i work with was putting a intake gasket on yesterday and said he saw two spots right where the head meets the block (i.e. the gasket). so i figured i would look at them to see what i saw, the spot by the front on the head was not even that big maybe the size of a pin head and the secound i could not see, also i am not getting any heat out from the vents and when i do get some its only luke warm and lasts about 4 or 5 mins. So my question to everyone is do you think it is a head gasket or something else? just can't figure out where the antifreez is going to. any help would be great. cause i am stumped.

 

Do you smell antifreeze when the heat is running?
When the car is running?
Is there a puddle/small drips under the car ever?

Have you properly bled the cooling system?

 

no do not smell anti freez at all, not in the heat or at any point when car is running. also there is no spots on the ground after car has sat. and not getting any heat at all when i turn heat on. sometimes i get luke warm heat but most of the times it goes to cold air. just replaced heater control vaule and it was clogged up but that did not fix the heat, so im thinking the heater core is clogged up, and still can not figure out where anti freez is going.

 

Yeah you could have a head gasket failure, make sure it's not wet under the battery.

Pull the plugs and look at them, you may have to do a compression check.

 

did you try totally bleeding your system .and do you have any low rpm studder.

 

the heater hose at the firewall drips on the exus evaperates at least thats were my leak was.

 

I'm going with no on the head gasket if you have no smoke, and no water in the oil, no miss your probably good... Heater core maybe...
