I think that is the ground wire for the filler tank neck. I did not realize the filler tank neck has a ground, but there it is listed in the ground schematics.
I only know the answer to this as I recently replace the vent valve on my TT. See pic. The ground attaches to the bracket bolt. Chances are the vent valve that attaches to the filler neck was replaced at some point.
Thx guys, this all makes sense. The gt3 did not have the valve because if the accident damage and mine was not in good shape and broke apart upon removal. This is why i never saw the connection. Ill probably just solder on a ring terminal or make a jumper.
That pic is of my new fuel valve so it should be easy to attach.
We can go on for 20 pages of speculation and analysis, and still miss the point. If this happened in the outer loop of Watkins Glen, the air-oil separator failed. Hydrolock broke the engine. If you're tracking a 996, you need the well documented IMS upgrade, and an upgrade to the Motorsports AOS.

Or u can actually read the thread and look at the pics of the dissasambled motor. It had a uaos, with no oil in the resi, and a dual row LNE retrofit ims bearing. It was confirmed with them that it was within its lifespan and waa perfect.
it was not the aos or the ims. It was the classic poor oiling of the rods over the lifespan of a 200mile motor. The #1 rod seized, it snapped, piston dropped below the cyl.wall, it got pushed back up by the broken rod and destroyed the cyl wall.

This is not assumption or speculation.
Lot of ways to kill an engine. Old age coupled with poor oiling is certainly one of them.
Sorry for the lack of updates last week. Even i have to take a vacation now and then. I did get my parts from DC Auto, those guys kick but for used parts. They sent exactly what i needed at a resonable price and packaged read well.
Motor mounts and firewall plate. Vacation spot, the gooldish one is my street jeep.
It’s true. My buddy’s 1980 Polish Fiat needed the alternator removed, so we had to take the exhaust, cooling fan shroud, front sway bar, exhaust manifold - all off just to remove the alternator.
that's what it's like on my 944 turbo engine. take everything off...
cool swap project. Did I misunderstand or do you think the value of the stripped GT3 chassis is worth $20K?

I doubt its worth $20k but it has a lot of value fixed. Ill do the body work on it later this year amd put it up for sale with a salvage title.
There is a bare chassis for sale now for $15k with no glass or doors and it looks like there is interest in it. Its a lot cheaper to swap your race car stuff into a new chassis then rebuild a car thats been put into the wall.

When I commented a few days ago, I didn't mean to make light of the situation, or doubt your conclusion. I was trying to offer more data points for all readers to benefit from. When I mentioned the IMS, it was just to reiterate how important it is to do on an M96, not that the IMS failure in and of itself is the catastrophe, but all the upstream damage it does to the valves/piston etc. Its the collateral damage that it does. Its the same thing with the AOS. When I first read your post,I saw the photo of the ruptured AOS, and without specific reference to the upgraded Porsche Motorsports version. All of the 996's will experience failures of the stock AOS in right hand high-G load corners, whether on street tires or not. The outer loop at The Glen, given its banking, qualifies as a high G load corner. But here's what happens. When the AOS fails, it creates an immediate vacuum that sucks a quart, two, or maybe more of oil from the sump up into the intake manifold. It's the double whammy on the engine; the hydraulic pressures in the cylinder pushing down on the piston/rod, at the same time lots of oil is no longer in the sump, which is already G loaded, created oil starvation. The Motorsports AOS is roughly $1000, where the stock part is around $250. A big difference, but again, if one is taking a 996 to the track, its a must. Every since I put one in my car, roughly 10 years ago, I've had no AOS issues, and I've covered over 25,000 race miles.
I feel bad for anyone who suffers engine failure, including the OP. There's a lot of things on track we can't control. But for the things we can; if the oil pressure sending unit is old and/or suspect, replace it. Its cheap and easy, and where it may not solve a more complex oiling issue, the problem more often than not is just the sending unit; upgrade to the LN IMS; upgrade to the Motorsports AOS.
Your points on the aos and imsb r well documented on this board and in my case had no bearing on the failure. U r correct that these 2 things need to be addressed for track cars.
U seem to push the motorsports aos because it has served u well but i encourage u to learn about the uaos system at about half the price of the motorsports unit and it has better protections.
The blown out aos bellow in the early pics was most likely caused by the combustion pressure escaping cly 1 as it dropped the piston. Its a well sealed motor and its the weakest containment piece if u pressurise the crank case.
