Just curious to how long or how good a car will run with a blown coolant seal, not sure what my problem is though, gonna get a pressure tester today I think, I just put an oem thermostat in and after about 20 min of drive time it starts to over heat, but if it just idels it won't over heat?

Sounds like the new thermostat is not opening. Was it OEM, or standard cheap replacement?

Get it sorted before you overheat the engine. Rotaries do not like to be overheated, so don't toast your motor over a $4.00 thermostat!

He says oem. Was it overheating before? Could be a bad thermostat, or maybe you put it in backwards?

How long they can run with a failure depends on how bad the failure is. Sometimes they start very slow and progress slowly, and you can drive these for quite a while. Sometimes they fail more suddenly and deteriorate much more quickly, and then you have to stop driving them. You know when this happens because they get to the point that they overheat and blow out all the coolant within 15 minutes of starting up, making it impossible to get anywhere before you have to shut down. Or other times they will be bad enough that they flood the internals with water when you shut down and then it's very hard to restart them...so obviously you can't continue to drive them that way, either.
