Help ID this piston, block, and head gasket

[87octane]

I've got a "mutt" motor assembled from way too many mismatched parts and I need help identifying what each part is so I can order replacement parts. I'm guessing this might be a 1.6 block bored out to 81 mm bore. The stroke measures out real close to 86.4 so maybe that's where the crank came from. Engine calculator gives me about 1780 cc's. The fellow who built it 3 owners ago can't remember any of the particulars. Any help appreciated.

The piston crown:


Piston crown clearly marked 80.985 and "+". What piston is this?
What rings would match this piston? The engine needs rings in all 4 holes, hole 2 is dead at 140psi, the remaining holes are 250 dry/350 wet. They started out all 4 at 380 before the carnage.

Block:


Is this a 1.6 block? A 1.8?

Here's the headgasket:



Is this a "one notch" ? Can anybody count holes and reference me a part # ? or thickness

Wow, someone has clearly installed gasser pistons in your Diesel block...


Looks like a 1.9 AAZ block. Need code off block to be sure though.


Scary stuff..

The guy who sourced the bottom end said something about 1987 Scirocco 16v 81mm pistons cut to clear the crank, but I can't find any matching 16v pictures to back that up. Anybody seen 16v pistons before?

Here's what I can see so far
Could it be an unmolested 2.0 block from south of the border?



How bout that head:



cyl head casting # and other marks:



Obviously hydraulic but is it an AAZ?

[Rabbit on Roids]

those are 16V pistons. a 1.8 gasser is like 1789cc or something like that. looks like a whole 16v bottom end actually. i bet anything its a PL block out of a later scirocco 16v.

[catlin_cava]

Its an AAZ Head

[catlin_cava]

Was that motor running if it had a gasser bottom end?

[87octane]

Where's the block code located?

[catlin_cava]

If it is an AAZ Block, somewhere on the block should say 1.9TD/D. Or if its a 1.6 it will be 1.6TD/D. IF there is somehting else there Post what it says.

cyl head intake ports are D shaped:



Intake manifold ports are oval shaped:



Matching paper gaskets on the spacers:



Is there an intake manifold that fits the AAZ head port exactly (i.e. D shaped intake ports)

[87octane]

How bout the IP. Looks like a 1.6 with the top screw?





Andre in Salt Lake City thought the IP adjustment looked very aggressive, very rich. Haven't touched it yet till I get the bottom end sorted out.

I'm not gonna publish names of those responsible, they may be board members....
Feel free to PM me for private conversation, I have extensive notes.

I limped this dog from Jackson Hole WY to SLC before it expired completely.   
Hey, at least the T3 is good 

May as well get it right while it's on the bench.
Is there a port matched AAZ intake manifold that's an improvement over the 1.6 design.

[Rabbit on Roids]

any AAZ or TDI intake will bolt right on.
the pad on the front of the block, just to the right of the main front oil drain, there should be something on there. whats it say? and is there a D or a 1.6D or a 1.9D or 1.9TD on the back of the block down behind the starter? if it doesnt say any of those, its not a diesel block.

and i really dont understand why people try telling other people that their diesel is running rich. they are pure idiots if they think you can run a diesel rich and lean. the amount of fuel going in controls engine speed, not mixture. there is no fuel ever introduced to the intake charge until its compressed in the cylinder and is almost to top dead center.

I've heard of guys using diesel short blocks for bomb-proof high compression gas engines.  I've never heard of this though... 

[burn_your_money]

Automatic to boot. I'm shocked, and impressed that she ran.

[Rabbit on Roids]

i noticed that too, starter is on the wrong side.
