So when i got my car there was a spare 12a block in the trunk lol. bare with the dizzy. turns over freely but meh who knows. What do you guys think crack it apart to check it out or what. m[akes psht for all three faces and both rotors. I mean out side of that how would YOU check it out???

 

If you have a friend with a bore scope, you can visually check your apex seals.

 

I would feel all 6 apex seals through the exhaust ports. If the spring pressure feels good, and since you say it has even fwoosh sounds, I'd take a chance and use it. Otherwsie, crack it open.
