Hi all I have a mazda rx7 engine out in a 1984 rx7 which is loosing coolant from out of exhaust after being over heated

engine will run strong after being push stated. is this a big job to fix what seals or gaskets have failed? thanks for any help I receive

is it a big job? the simple answer is yes!



you've done one or both of two things: (1) busted the water seals and/or (2) warped the rotor housing. either way, the engine will need a rebuild and it will more than likely require housings in addition to the seals and springs.

thankyou for your quick reply shame its a lot of work to fix as it was a really good engine I have another engine from a early rx7 about 1981 but this car was really slow and didnt perform as well I will try looking for another replacement

well, if you plan to replace as opposed to rebuild, let me know what you're going to do with the engine coming out. where are you located? good luck either way and if you have any questions throughout the process, just ask.
