looks like a crack at the bottom of the cylinder? perhaps just more broken piston? regardless, need for new sleeves and to deal w big chunks of metal flying around the bottom end. my price was premised on bad crank as stated in the post. i was also talking Cdn $; presume you understand that, although called 'dollars', they are not the same as american $. yes, you may be able to 'shop around' for better pricing, but should avoid confusing shopping around with doing things half-arsed, such as only sleeving the damaged cylinder, filing the burrs off the crank and slapping it back in, etc.

$5k is a good price, newart should take it quick.

Fair call
It is always easy just to assume everything is broken and spend way more than necessary.
That was my only point.
Break it down and analyze parts individually.
I think all of us would really love to see what's inside

You know, I was actually thinking about the shuttle and the incredible post-accident investigation just earlier as I was posting on this.
Crazy

Just pull out all that broken stuff and bolt it back together as a 3.0L 5 cylinder.

Hahaha..... did that once with a datsun pickup. 3- cylinders for months. Wouldn't climb the hill to my house, so I had to come at it from the other direction. Haha

Yup, 1/6 power loss, or 16.6%. In my case, with 268hp, i would drop 44hp,
The bigger issue would be balance, and the car would vibrate apart methinks given its a flat 6.
Good things to ponder tho

Check engine light would probably be on with a million codes running on 5 cylinders, ha ha!

Is it time for an update on the Youtube channel?
The PORSCHE BOXSTER as seen by NewArt

I know this is not a happy moment, but a video tour of the engine carnage would be very informative to those of us who follow.

Brighter days ahead.

Yes, I am documenting the 996 teardown. I will post it on my YouTube channel when I have split the case.

So, here's the update. Structure looks okay. Sleeves are a bit wanting. Better than I thought. Crank looks fine, but what do I know?

Wow, that is something.
From Pelican...

Cylinder Liner Cracks: In an effort to reduce costs during production, Porsche utilized a type of insert-mold casting process to directly incorporate Lokasil cylinder liners into the case. While this is a neat way to reduce the total number of parts used in the engine, this design basically casts a wearable part into the engine case. There is no factory replacement for the liners: when they wear, the factory expects you to buy a new engine case. In addition, the design of the cylinder liners allows them to "float" within an area filled with coolant.

Excess vibration and twisting from the normal operation of the engine appears to be causing some cracking in these liners, resulting in a small chunk of the liner breaking off. This "D-chunk" problem seems to ironically occur mostly in gently driven cars. Boxsters that are driven hard at the track or on the street do not tend to see this type of damage. At least with respect to the track cars, one theory is that these cars tend to have their oil changed much more often. The problem affects mostly the 2.5 and Carrera 3.4 engines: the 3.2 Boxster S engine appears to be unaffected because it has thicker cylinder walls than the 3.4 engine. When this failure happens, you will see oil and coolant begin to mix together, or a slight unexplained coolant loss.

If your engine experiences this failure, it can be rebuilt using LN Engineering's Nickasil liners installed. They take your old case, machine out the cracked or damaged Lokasil liners and install an aluminum Nickies insert which is stronger and more reliable than the factory cast-in liner. In addition, with the installation of the liners it's fairly easy to increase the bore of the cylinders which translates into increased displacement and more horsepower. If you go this route, you will also need to use some aftermarket pistons and perhaps update the software in your DME to accommodate the change

Well, maybe I can get $ 20 for recycled aluminum. I do have a pair of cylinder heads/valves/cams that I can put on eBay...

Wow that must have been some knock before the engine blew! Do you understand what happened? My understanding is the IMSB problem should have thrown the timing off, leading to pistons hitting valves and then other bad things. But you say the heads and valves are OK???

Perhaps you can find a used case half ? Are cases a matched pair ? Size, obviously, sure, but wonder if you can find just a used half.
Or , this option here:

Case halves are matched, so no go for mixing them. The link that you posted is for re-sleeving, so it needs a core, one of which I have not.

Grant, the heads and valves “seem” to have escaped damage but I’ll have to take a close look.

Weird. I wonder why folks sell case halves singly. All over Ebay.
