    Nope.   We can narrow it down with more info tho:   1. Check for gold sticker on the valve covers. If it has these (they indicate hydro lifters), it came from an 83/84 automatic, or 85-89 Brat or

    Ok - so to summarize (I'll update as people post):     Engine serials / build dates:   - EA81   799337 - 07/81 931272 - 01/82 009899 - 04/82 300305 - 05/83 460419 - 01/84 665918 - 11/84 8

  • We COULD post engine numbers from cars with a build date which would give us a range after a significant number of people posted.

Just checked my brumby rego papers for a 1985 model :

 

VIN : JF3AU5FR01G5 ******

Engine No: EA81 110685

 

Dunno if that helps, but I'm also not sure if that is the orginal engine ... :huh:

 

Ciao, Bantum ...

I have a chiltons manual that list numbers for 1970-88 model subarus. I have all these numbers. Hopefully they are readable

EA71 / EA81  79 to 84  JDM for Leone 2nd gen.

EA71 / EA82  84 to 93 JDM   for Leone 3rd gen.  (then since 94  Impreza with EJ engines)

EA71  78 to 81 NZDM for Brat  1st gen.   (last of 1st gen in 81 had EA81+MT D/R)

EA81  82 to  94  NZDM  for Brat 2nd gen.

 

Understand that USDM dates a year behind in some cases, and the Brat was discontinued in US in  late 80's?

Surely  Subaru USA has a database to find out about its (year) history (engine number ) if USDM.

jf3au5 6/89 build got ea81  882505 [now deceased - autopsy looks like minimal oil/young boy driver with tacho ]

 

Forgot I even posted this up !!

 

OK, no one has mentioned that some EA81 blocks did not have the extra 14mm hex keyed plug at the front of the distributor side block - into the water jacket? I have one without the plug or threaded hole. The crank that went with it did not have the space at the back behind the flywheel for that oh so pricey orang seal/washer/whatever it is meant to be. Came out od my 3/84 sedan auto

 

074839 for a jan 92 made EA81 Brumby , suspect it sounds like hydro ??

 

604825 for 3/84 EA81 this one has the no room for seal on crank or the water plug at front

 

882505 for 6/89 EA81

                             engine no.  :  EA81 153623

 

this was pre VIN days,before this became a requirement.

Best two years with ea81 engines are 1983-4

  • 2 months later...

So after reading all these posts I'm fairly certain I have a very early EA81.

 

Gold stickers on valve covers saying 'Don't adjust Valve Clearance' Hydro lifters I am guessing

 

Serial # on block 002766

 

With a NiiponDenso dizzy

 

Oh On a 86 Brat with build date 12/85.

Here is my dilemma: I ordered tune up parts and got the wrong ones... The original owner replaced the engine back in '98.  Using GeneralDisorder's break down, my engine is pre-81 or post 85. I don't have magical golden stickers on the (blue) valve covers or the previously mentioned 10mm bolts on the bottom of the heads. My Engine # is 889710. It does have a single grove pully. Any idea what  my engine came out of?

bump for more numbers? non original ea81 hydro in my 88 gl sn: 684238

I'd love to play, but before I do I'm having serious concerns my car was factory turbo. 1983 wagon turbo auto, MAF has "83 turbo" written on it, transmission has "84 turbo" written on it, I have no "turbo 4x4" decal on the side and when I looked up a list of trouble codes, it said 1983 carb and 1984+ Injected and my '83 is injected. Anybody know of a way I can make sure it's turboed from the factory? I'd rather not spend money on a car fax just to figure this out. Once I do I'll post my numbers.

 

Thx!!

Factory turbos have a 5 for the 7th VIN "digit".

Use the 84+ injected code chart.
