yah! your colant seal is probably toasted. take it into a gooood mechanic that actually can dye test (a diffrent type of pressure test) it to tell u if it is the coolant seal. sometimes the seals have a slight leak in them and it makes it hard to tell if there is a real problem. it took me three radiators to figure that out.

 

when they rebuilt your motor they probable pinched the coolant seal.

 

hahah i am the new owner of this rx7. i think both o-rings are cracked. the first rotary isnt bad as the 2nd one tho. ALOT of white smoke so its a coolent leak. the car is goin to be fine tho. street port is coming in next week.

 

How much did he sell it to you for?
