EAO Case ??

[cary]

Doing research on getting a new case.

The serial # on my case is EAO 26057. It is in the 2.0 L location behind the oil filler neck. What do I have ?

Go to the above link....an EA case is a 1.7.

That's what I think too. But the #'s are in the 2.0 location. Not the 1.7 location. And it's not EAxxxxxx like the chart. It is EAO_26057.

I'm wondering if it has a replacement case ? It's shot anyway with the hole in it. But what crank and rods does it have ?

As I said on the Shoptalk BBS, I think the "O" might be a "0" (zero). The location of the number was used on at least some of the VW applications. I'm betting that the engine case is from a VW 411 or 412. Some of them did have the 914 dipstick and oil filler setup.

Since it's an engine that was swapped in, it's really tough to say what crank/rods/pistons/cylinders it has. If it wasn't rebuilt, then it's a stock-displacement 1.7 motor. If it was opened up, then perhaps the 2.0 parts from the motor that used to be in your 2.0 were used.

Are the heads the proper 2.0 914 type? Do the spark plugs exit the engine tin on the top horizontal part, or the side vertical part? 2.0 heads would be a strong hint at 94mm cylinders, though larger could be used. There is some possibility of a stock 1.8 displacement also, but that's not as likely.

The only way to absolutely be certain is to pull the heads and measure the bore and the stroke.

I have a long list of stuff that was done in the restoration.

It calls out 2.1 displacement. It does have a cast iron oil pump.

Can't remember the sparkplugs. It does have all the 2.0 fuel injection and air cleaner.

I didn't get an e-mail on your Type4um post, sorry.

Came home reread the file. NEW CASE - line bored. Missed the new case on the hand written notes. Not transferred the the typed copy.

Heres a picture of the # and the sparkplug location.

EA motor (that next character is the same as the zero later in the serial number); 2.0 914 heads. Again, the location of the serial number says 411 or 412, and I think it was the "variant" (station wagon) body style that used the same dipstick and oil filler location as the 914.

A brand-new case should not need to be line-bored. I'm guessing "NEW CASE" meant "new to me".

I would assume the same thing. New To Him...........

If I could get my scanner to work. I'd shoot a copy of the restoration list. It's a shame he forgot the distributor washer.

Hello

AFIK the factory moved the engine# location on all 72 on engines to the tower position.

The 914 block is identical to the sedans.
The Variant blocks are identical to the Bus blocks.

If you have a EA case and they listed your engine as a 2.1, the possible combo is 96mm cylinders and stock 2.0 (71mm) crank (2056 cc). The other way is stock 2.0 cylinders and a stroker crank, maybe 74mm (2055 cc). In reality, there are many combos.

The only mod required would be to the case. The cylinder holes would have been machined to accept the 96mm bore. The 2.0 heads will accept the 96mm cylinders without further machining as I remember.

To fix it, use a GA or GC 2.0 case. Or if you use a 1.7/1.8 (W, EA, EB, EC) case, have the cylinder holes machined to accept the 96mm cylinders.

Using a brand new case (green case) may not be the best option. The components of an engine go thru heat cycles in use. Core shift can occur during these heat cycles, creating a slight misalingment from factory specifications.

"Used" cases (seasoned case) have already undergone heat cycling. When machined, they hold the tolerances better as any core shift has already occurred.

If you desire, email me as I have a couple of 2.0 bare cases and several 1.7/1.8 engines.

Ron, the 96es are "slip-ins" on the Type IV. No machining required, unless you are using the thick-walled 96es on a 1.7 engine. In which case you have to have the heads machined, not the case. (There are thin-walled 96es that slip into 1.7 heads with no machining, but they're really very thin!)
