997.1 Piston Slap and the heartbreaking decision

I agree, universal average is a silly and misleading concept in the first place. It would only make sense if it was much more granular like universal average for the exact formulation of oil you are running (not just brand and type, the formulation can change over time too which would need to be controlled for) and for the exact same engine. Also I have literally never seen a negative comment from Blackstone... it's always "another great report!!! your 911 is awesome!!!" even when it's just an average report or has more wear than I would want to see if it was my own car.
I just use them for the quantitative #s and interpret the results myself, essentially ignoring the commentary.

I particularly like the ones where we see viscosity shearing, a high TAN, and they tell the owner things look great and they should extend the mileage interval on the next sample when they've already run the current sample too long.

I know how you feel, pretty much the same thing happened to me about year and a half ago to my 997.1 C2S.
For me it was a both a financial and emotional decision. My car is a daily driver and my first Porsche. I had not done too much to it except an aftermarket exhaust. What I really wanted was a GT3, thought one day I'd get it... then the bad news.
With prices the way they are for those cars and likely will be for a while, I decided to keep the roller and rebuild. That was going to be a lot less expensive than the GT3, also giving me the peace of mind knowing that it would be a well sorted car and at the same time making it exceptionally fun to drive.
So I went crazy with it: 4.0L Nickies, IMS Solution, Bilstein coilovers, GT2 folding bucket seats, factory Momo steering wheel,... it's an event every time I drive it now, super engaging, loving it more than I ever have, simply an amazing ride.
Whichever direction you go, best of luck, sending good vibes and encouragement!

I chose Slakker based on the transparent pricing of the packages, the more reasonable lead times and the quality of the mechanical approach with the Hartech kits.

How different is the Hartech solution compared to the LN engineering solution? I am considering selling my '88 and replacing it with a 997 but want to have a plan in place when bore scoring occurs. I spoke to LN and their part of the work seems very reasonably.priced but then I talked to the shop they recommend here in DFW and they quoted 30-35k for their part of the work. Its VERY respected shop (they've built several track only 911s for a good friend of mine) but that seems like a lot of money, on top of the price of the car purchase itself. For comparable $$ could easily find a 996 Turbo with a bulletproof engine.

You are correct about the 996TT. The 997 is an awesome model but would require these modifications/investment to be as bulletproof as a 996TT out of the box.

LN and Hartech solutions are fundamentally very similar. The differences (closing the deck, etc) are what I would consider not significant.

I agree, the 997.1TT also uses variable vane technology to reduce turbo lag. I have not been close to the market prices of the TTs recently (I just looked quickly at the history on BaT) but to me it would come down to the price differential and details of the 996TT vs 997.1TT I was looking at. If you can get the 996TT for way cheaper it is ultimately the same as far as the engine goes (both bulletproof stock) so to me it would come down to how much money I am saving vs the trade offs.

Will you be sending your car to Slakker and having them do the engine in/out? You should do a writeup and let us know how you like the 4.1 when its completed!

996-GT3 would be even better than a 996TT but costs much more so that's why it didn't enter the conversation. If you look on BaT the ones that just sold recently, both 2004s, fetched nearly $150K. That is a different price league......

997.1 TTs do have engine issues!
