just like the title says. i bought my ac a year and a half ago and the engine was supposedly rebuilt, and i do not remember what all was put in the B18B. how can i tell if it was rebuilt, or if it has actual quality stuff inside it, and not stock internals. someone help please.

 

i know this sounds like newby question, but come on now. TO THE TOP

 

by doing a leakdown and takling it apart...
