Well... after two years I think it is dead. It got me around for quite sometime; I can't let it go. I'll probably swap a TII in it in a few months. I just want to double check and make sure that the coolant seal are causing this problem. Radiator = full, Overfill = full. It is boiling for some reason and I can't figure any reason other than the coolant/apex seals being f'd. It is fine sometimes but then other times it decides to overheat partially. On the stock gauge it manages to show between medium.hot sometimes.... I thought it was impossible. I replaced the thermo and checked external leaks, but as stated it isn't running low; just boiling for some reason. It ran fine all night and even had to run it hard for a few mins to make a girl realize that my 20yo sports car is > than a 5yo mustang. Anyways, do you guys think that it is just the coolant seals finally gone all the way or maybe an apex seal cracked? The engine has 143k on it and more than 20k miles has been put on it since the radiator cap failed and a coolant seal was blown. It still has good front rotor compression and has A LOT of power. I can still hit 0-60 in 8 seconds. It was fine tonight but I'll drive more tmrw and update if it starts overheating every twenty miles again. Just trying to get an experts' advice on if it is actually done now or if I can squeeze some more milage out of it.
I might have had a bit to drink when I typed this but I've spent 47 straight hours trying to squeeze more time out of this car. It reminds me of myself... 20 years oldd, nobody believes it can amount to anything, but it keeps trying.... Just sounded a bit bent.

 

how did you bandaid your coolant seal? might have some closed off chambers filled with seal/gunk.

 

wow two years on blown coolant seals? i was able to last about only one year before the engine became unreliable for daily use. do the coolant seal test and see how bad it is.

 

I been on a coolant seal leak on mine for like the whole time ive had my car, i overheated the motor unintentionally after installing it after it was rebuilt and come to find out it was my fan , not even something i did wrong..so nothing i can do about it now..but yeah i got like 20k miles on it in the 5 years the coolant seal leak may have been there.

 

does it have the original rad? it could be done, what kind of coolant? what kind of shape is the clutch fan in? does it still lock when hot? Do you still have the undertray on? is the a/c system still in?

does it overheat while cruising? or at idle

 

Everything is original and it has the ac still. 50/50. Undertray is still there. Everything is operating correctly, and I didn't really "bandage" the coolant seal I just changed the coolant every 2k miles or less because it would get a lot of combustion gasses in it. Oil every 2k miles or less also because it would get milky....

 

sounds like it finally bit the bullet. dont feel so bad though i spent 2 years dropping in a t2 motor and tranny and rear end into a 86 gxl and the motor was a mazda reman with 20k on it and it runs over half the temp gauage on a regular basis and its stock. i just gave up and drive the damn thing lol
