So I discovered why it was not turning over.

Started by removing the head but there is a bracket on the front behind the IP that needed to be removed so the IP came off.

As soon as the IP was off I could see the problem.

It seems there is a crank inspection hole, I.E. non factory installed hole in the front of the block.
It apparently also has some non factory installed quick release rods as one of them is sticking out the inspection hole

On the good side, the head appears to have been rebuilt recently. Clean clean.

So the search for a hydro 1.6 block ensues.

Why do you think the hole with the rod was there? Seems very odd.

Perhaps the same crank inspection hole with the quick release rods as this guy ?

my first guess would be poor reassembly.

the inside of this engine looks brand new, like it was just refreshed.
The #1 rod let go.
I'm preaty much going to have to replace the entire bottom end.
Crank
Balance shaft
Balance shaft pully
rods/ pistons

In my air-cooled days I drove a Beetle with an impromptu crank inspection hole for a couple hundred km... you could actually watch the piston go up and down and everything. Finally just for laughs I drove it to my favorite VW shop and asked if they had any Crazy Glue... when he asked why I took him outside and started her up... "it started making a funny noise a week ago".

Did the rod let go at the big end? I have seen a patch welded on the crankcase below the water jacket on such an event, mind you not on a VW but an ancient Brit machine and it worked too.

Well I've not got it tore down far enough yet to see how bad it really is so I'll have to report on that later.
You are correct however, repairing blocks really isnt that hard.

Lock-N-Stitch lock comes to mind. Good stuff right there.
