i have a b16 hatch. the coolant gets sucked up to fast! i wanna know what can be the issue. I havent has issues with it overheating yet! but i wanna know why its suckin it up so quick and my car is burnin oil i dont smell it but my oil is short for some reason and i changed it like 2 months ago. Another issue i am having is randoms reving up on my car!?! the car will kick up to 4 or 5 rpm an im not hitting gas and not on any gear?? Also is their anything i can do about me goin 70mph and my rph is up at 4500 to 5000, my gear ratio is real short. And i know its cause of the tranny. But it seems like its missing a gear

 

Sounds like headgasket

Trade me transmissions.
