I tried to search other forums but couldn't find a solid answer
Started the car
Had coolant leaking out of a hose behind intercooler
Tightened it was good
The next morning
green Coolant was comming out of the exhaust
What causes this?

(Radiator and reserve tank kept having air escape I took off the caps to relieve possible pressure)

 

Bad coolant seals. Time for a rebuild.

 

I figured as much since the last rebuild happen in 99
But thought that I would be fine since the owner stopped driving it shortly after and has spent more time sitting

Also this wouldn't indicate any housing or plate inside the engine breaking would it?

 

Yup, or a cracked front iron. Based on your very brief description it sounds like you have a bad coolant seal on the combustion side of the rotor. This will cause the cooling system to pressurize while the engine is running and that pressure will push coolant back into the rotor housing after shut down.

 

Well I hope it's just a seal

The coolant comes out while it's on not just when turned off
Either way
Should I avoid starting it till the problem is solved
Or can I start it to test some things?

 

You can start it, just make sure it doesn't overheat while testing some things.

 

Awesome thanks

 

Dont wait too long or it'll build up rust and youll need a whole new engine.

 

if i dont get to it soon or i will get a new engine as its been part of my plan if this
one doesnt do well because someone messed with it too much

turned it on to do that "champagne test" and i could see quite a few bubbles in there
but back in the exhaust it stopped coming out even when i turned it off
but from the same part the bubbles came out white vapor was coming out too
does this still suggest the same thing as coolant seals broken?

 

Still bro. you should take the engine out and disassemble it. All the parts should be in rebuildable condition since it is currently running. Dont waste those good parts. It'll save you money in the long run.

Let me know if youre going to waste that engine, in that case, ill come pull the engine for you if you let me keep the block.
