...all the EAxx numbers? You know, EA81, EA82 etc etc. What the heck do they all mean? I've searched for a thread but find nothing. I'm ignorant about alot..so thought I'd maybe could take one thing off the list!!!

those are engine designation numbers for the old-gen cars (pre 90, or loyale).

 

in most cases here, a certain body style is also refered to by the type of engine it contained.

 

EA81 - OHV, uses timing chain (I think), I don't know much about them since I don't have one, typically early 80s and were carbed

 

EA82 - OHC, uses two timing belts, non-interference engine, used mostly in later 80's cars, and loyales, mostly FI, some where carbed

 

hope this answers a few questions you had.

 

edit: here's a good post that outlines some of the differences. http://www.ultimatesubaru.org/forum/showpost.php?p=153266&postcount=3

MY HERO!!! Thanks for the link. Do you know if you can find the EAXX designation stamped on the engine anywhere?

EA designation is stamped on the engine. Looking down below the manifold on the passenger side by the timing belt cover is where you will find it on the newer engines.

 

BTW, EA81 is a pushrod engine
