I'm looking at this S7 engine block which a local guy is selling dirt cheap, he has told me it has good compression but its been sitting in the bay of his car for a year without running.

What sort of problems might I encounter when trying to restart an engine thats been dormant for this long? I cant test it out as its just the block ( no manifolds etc) . Is there anyway I can check its condition without trying to start it up ? ( aprt from cracking it open )

 

The "poor man's" compression test will let you know if the engine has any compression:

Apex seals can stick over time. Use some MMO in the chambers to work each apex seal (through the exhaust port) before you stick all your components on it.

 

mmo? is that like a 2 stroke?
