hi folks, 
running an inline ABA� engine with 1.8 head. I've got the original diesel coolant reservoir which are not cheap to replace. this IS a replacement but i can't remember who i bought it off of, although i think it was van-again. the replacement is leaking out of a crack at the base of the top filler tube thingy. What would folks recommend using for a short (long?) term fix before i get another? jb-weld?
