Im losing anitfreeze in my 87 4runner with a 22re and i dont know were its going. I cant find a definite leak but its losing like a gallon a day. I quit driving it and still cant find where its going. I did a compression test and as far as i can tell it isn't the head. Any help would be great.

 

Did you look at the heatcore?? does it smell coolant in the truck ??
radiator leak ??Did you look all hoses ??

Just for making sure take a look at you're engine oil if it's mixed with coolant.

hope that can help a bit
