so I found a T II engine but its lost compression. I have no problem rebuilding it but if its lost compression is it possible the housings and rotors could have been destroyed?

 

you won't know until you have opened it up.
You can try the ATF trick to see if the seals are dried up or sticking.,The seals can actually be felt with your finger through the exhaust ports.Check to see if the seals are Bouncy and Evenly Structured.If they are jagged then you can bet it would have caused housing damage.
But if it has lost Compression,it is usually going to need a rebuild.

 

You have to open it up and see.

Why buy a blown engine?

 

well its a pretty good price. all he said was he had it running then he parked it for a year and it wont start now

 

More then likely its just stuck seals then. Pop off the exhaust manifold and press on the apex seals, if they don't spring back then they are stuck.

 

exactly what i wanted to hear thnx man
