i have a 1990 Mazda rx7 GxL...everytime i turn on the car, it starts vibrating and making this really weird noise..and smoke comes out of both mufflers...i checked under the hood and it was completely out of coolant...but, i had added coolant two weeks beforehand...so my father says that i have a leak in the gasket...if its true...more or less..how much would a gasket cost for an rx7???

 

if i were you i would take it to a specialist. It sounds like your car has a cold and needs a check up!

 

is the temp gage rising??? have u checked under the car to see if you have any puddles of coolant? check what's actually causing the leak

 

If it blew a coolant seal you probably need to rebuild it. Check the oil, I believe when coolant gets in there it makes a white froth ontop of it or something *shrug* It of course all comes down to where it is leaking...

 

yup....drox is right...check the oil..it makes it look milky..if nothing there..then you should check somewhere else for the leak...hopefully its just a hose or something

 

You might need a good rebuild...cuz if your loosing coolent thats not good.

How's the temp gauge looking? HOT! If you most likely your screw.
Sorry for telling u this...

but i now how you feel tho...
