A couple a months ago we notice that my engine coolant been leaking a little and just today its starting to leak more and when its idling I can smell the coolant and when its parked and the engine isnt running it leaks to the grown alot.. I cant see where it's coming from and I would like to know where or what to do?

    My first guess would be the classic intake gasket leak... Do you smeel the coolant as its burning or just leaking a puddling up?
