Let the rebuild begin!
This is a '99 cabriolet that was taken out by dragging it's belly on a gravel road. I straddled a ridge of loose gravel which made contact with the oil pan area and broke a hose clamp on one of the water hoses. The water leaked out and the engine overheated and then quit when my wife went to drive it the next day. When I tried to restart, both exhausts were dripping coolant. Now, after a year of procrastinating I have gotten started on the repair. What I've got to move forward on this project is: A core motor that I can use should the heads be cracked or unrepairable. Also, the shortblock could be used as a core should I need to purchase a factory rebuilt bottom end. I've got my shop set up with a reasonable set of tools including a 996 cam alignment kit, a lift and a hydraulic table. I've got a Bently manual. The only skill set I bring with me is a basic knowledge of mechanics from high school autoshop and about a dozen or more prior engine builds/refresh on my racing cars over the years (mostly v-8 and some imports).
Please chime in with suggestions as I proceed.

Looking forward to following the project. Let me know the parts you may need since I took apart my failed 3.4 last year just to learn and have all of the parts. I will be happy to contribute parts as long as you post all the work you are doing and pay for my shipping. Hate to throw good parts away but I need to start getting rid of the stuff...would love to help a good cause.

But, what are you going to do about the road and the chance of the same happening again?

Looking forward to watching this unfold. I'm only a hobbyist mechanic, but happy to help in any way I can.

If I were in your shoes, I'd take the Knowledge gruupe online re-build/engine course. I think it would be $400 well spent. Good luck with the re-build!

Thank you for your interest and offers. The original motor had just been rebuilt/refreshed with bearings, hone/rings, updated rod bolts, IMS, valve job, gaskets/seals, waterpump and starter at the time of my purchase. The seller had receipts totaling $14.5K. I put a couple thousand miles on it cruising over the summer. I hope that the cyds remain round and are not cracked. If they visually look good I will take the shortblock to a machine shop to check for oval, taper and ?magnuflux? (unsure how to adequately mag an assembled shortblock?) :
Lowpue: It's nice to know that someone has spare parts, should mine be unsalvagable.

I did look into this. Are you referring to the online, or the in-person workshop? What I surely will need help with are things like bearing clearances (?.0025 rods/ ?.003 mains?), bore specs, ... also, I've never set-up valve timing on a variable timed engine. It looks like you just trust the Porsche tool to get it right, rather than using a degree wheel? ... I'm sure I can get it apart. Getting it back together will be the journey!

You won't be able to Mag anything until each component is disassembled, best part is you will have some great help in this forum.
