Overheated 1997 1.8t. My son drove it w/ no coolant. New head or new engine?

When you pull the head you will be able to see the side walls of the cylinders
you can see then if you need to replace the whole engine or not. If you warped the heads there is a good chance you wrecked the rings too.

It will not tell you if the rings are bad - if the head is warped. You can't isolate the cause
leak down tells you if it is rings or valves - or if you have a warped head/ bad gasket but not if multiple things are bad.

I don't see how he's going to be any better off with the leakdown.
I still think he has to pull everything apart to get a clear picture of what condition the engine is in. The leakdown doesn't really cost anything, but I don't think he'll be in a better position to make a decision as a result of it.

The pressure will find the path of least resistance...
but if that happens to be a BIG leak (say in the head), the air may never find it's way into the crankcase. So now he commits to a head gasket and whatever needs to be done with the head...but when he pays someone to take it apart, he finds there is more severe damage than originally thought. Or worse...everything else *appears* okay, and upon reinstalling the head, there is still no compression and leakdown #2 confirms another issue went undiagnosed.
If he was doing the work himself, it's not such a big deal, but if he's doing the diagnosis, and paying someone else to do the work, he's opening up a lot of liability for himself imho.
I've been down this road, and it bit me in the a$$...

So, this is the big question....... With this particular engine, is more likely...
With this particular engine, (1.8t)is more likely that a severe overheating would damage just the head, or would a severe overheating be likely to cause other non head damage?
Does anyone know anyone with this engine who has had engine damage due to overheating?
