Hi guys,

So a few days ago, my engine started to overheat, but there was no visible signs to any leaks. I let the car rest a few days, and drive again, and after a few minutes, the temperature shoots up again. I noticed that the radiator overflow tank was full and overflowing.

I took it to a local shop and they looked at it, and found exhaust gas bubbling out of radiator fluid, which was adding temperature and pressure where the coolant could not do its job.

I wanted to see what you guys thought of it, and typically, how much $$$ am I looking at, to fix something like this (given the mileage ~140K), where the fix ultimately means a new engine block...

Thanks!

Sorry, forgot to mention:
I have a 91 RX-7 Convertible (of course non turbo)...
Thanks!

sounds like bad coolant seals and if u think u need a new block u might as well sell your vert to me

 

That was what the guys said too, but in order to fix that, and given the age/mileage of the engine, their recommendation was to rebuild the engine, but I'm not sure if that's really the best way to go...

 

nope theres not a better way to go. you either rebuild your egine or buy a new one, sorry.

 

complete rebuilt looking at atleast 1k

 

You need a rebuild and 0-3 irons depending if the water jacket broke away and also possibly 2 housings depending on the condition of yours. You wont know what you need till you crack the engine open.

 

let the teardown begin!!

 

Sorry bro time to clear the calendar annd drain the fluids. I think you need to start a rebuild, but now you can think about getting a turbo on there

 

thanks guys! Hmm. Time for a re-build... I got an early estimate of complete engine rebuild including all new blocks and etc for 4500... though they are known for being on a high-end but reliable... what do you guys think?

(Sorry, won't be able to do this on my own... don't have the space/time/resources available yet, but eventually, this would be fun project...)

Thanks!

 

The cheapest quality rebuild would be shipping your engine to http://rotaryresurrection.com/2ndgen/index.html
