Ok Thanks. Still waiting on tech here to get back to me with any info. Not helping my anxiety level or instilling confidence.

Without the sooty left pipe I would not worry about this.

I recommend taking it to CARMAX and walking away with a check. Time to get another 911 without the headache.

And let some unknowingly poor dolt deal with it after they have the car of their dreams?

That's what the unlimited CarMax warranty is for.

Did you happen to drive in all weather conditions, including very cold? Below 20 degrees? There are some threads about the coincidence of cold weather and scoring.

I can't tell you what to do OP, only what I did, which was get an RND engine. Offing the car knowing it had a serious issue was not an option for me ethically. Buying a used engine I felt was a crapshoot. No doubt there are fine indie shops out there who can do a fine rebuild. The problem is, all shops will probably tell you they can. If you do consider having an indie rebuild it, I suggest printing out the list off RND's website of all the things they do to their engines, and make sure the indie will do the same. I did that, and got told that many things were overkill...yet the cost from the indie was the same. I see nothing wrong with overkill, especially when it doesn't cost any more than the bare essentials? One thing I can say is RND and SSF (the company in charge of sales and distribution) have some of the most awesome customer service I've encountered in a really long time.

How do you know it's a scored cylinder? Without a bore scope you're just guessing. It could be a bad valve or lifter too couldn't it? Just trying to think positive here.

If you can swing it I would go with the RND option.

I will second Tuners RS in Coral Springs. They rebuilt my 2004 after IMS failure. Great guys to work with and the price was reasonable.

Anyone here expecting a Happy Face for this post? Sorry. As per this AM:

There is a longitudinal score running the length of the #6 cylinder bore. This after 48K miles of obsessive maintainence, upgraded oil, 3k oil changes, and TLC bordering on fanatical. A fatally flawed product.

I am exploring options for replacement engine. RND is favored by repair shop. Not have firm cost yet.

I am so f'ing pissed I am close to certifiable at this point. Just thought I'd share that.

To be continued
