Bye oil, bye motor.. Now what?

Alright it's a freshly rebuilt 1.6 naturally aspirated diesel just did rod bearings main bearings piston rings fresh hone, did all the gaskets and seals basically just a mini rebuild I was driving it and one of the oil cooler lines got cut by the radiator fan ( I have a oil to air cooler) and I was going down the highway and it ran out oil I noticed that it ran out well maybe a minute or two after all the oil was fully gone because no oil pressure at that point I pulled over and parked it fixed the oil line and put fresh oil in it started back up and had a nice little knock and the head gasket was going I can tell because I saw it bubbling pretty sure it over heated obviously when it ran out of oil... Just about to pull it and start tearing it apart what am I going to be looking at? Could I get away with a new head gasket rings and bearings? Or is it going to need a bore, crank, plus all that I already said?

There is absolutely no way anyone over the interwebs is going to be able to reliably tell you what your engine needs by looking at a picture, and if anyone tries to tell you you're best to ignore them completely.  

The damage is dependent on many many factors... you'll need to tear it down completely, mike everything, and start making a parts list.

No I understand no one can tell me what to do I guess I was just looking for insight I've rebuilt a few motors but nothing ever like this normally I give it a nice hone and all new everything( not to experienced with a caliper and mike) I have the bently with all the measurements now what do I need to start measuring? I know I have to check the head it did get pretty hot.. But for checking the crank and  cylinders what do I need?

invest in a working oil pressure system for the next engine maybe?

Lol yea it was working ( not the warning indicator) but the gauge was I had been having problems with over heating and the oil would get very thin when hot so I unplugged the indicator, the day before this happened I had fixed the over heating problem and just hadent plugged it back in. 8(
(also I didn't drive it with the over heating issue I had unplugged the indicator while working on it)

Just my opinion, but if you have a good machine shop available I'd recommend entrusting them with the measuring part.  You'll need several hundred dollars worth of micrometers and bore gauges to do this well (the same couple of hundred dollars a machine shop will charge.. if not less) but what you'll be missing is the "feel"... particularly for using the bore gauges.  A shop that does a lot of engines will be able to quickly make the required measurements accurately and reproducibly and then advise on a course of action... those of use that have only rebuilt a few engines just don't get enough practice, sadly. 

I've personally bought all the tools... but very quickly realized my machinist will do a much better job than me... working in 1/1000th of an inch can be tricky for a weekend warrior.

I would do the rings for sure. I have heard stories of guys draining the oil and running an engine for several miles trying to get a warranty. They would fill it back up and just have low compression and oil usage. VW's seem to do really well on the rod and mains, but you said a slight tick so ... check your head . Make sure there isn't aluminum trying to become one with the cam. The rings basically get tempered and aren't as good as they used to be before no oil.

Seeing the picture though and knowing what a pain everything is to put in you should do the nessesary things to make it go the distance while out. Unless you have a plan for putting something else in rather quickly. It isn't that much more to pull the pistons after the block is out and you have already taken the crank out to look at the mains.

If you could have dropped the oil pan and looked at the rods before pulling the block that may have saved you some time. If they looked good then the rest probably would...risky but worth a shot maybe.
