I’m pretty good managing money and making money related decisions. I am not going to force my decisions or opinions on anyone, what I can tell you is that for 8 years, fidelity, vanguard, fisher and a bunch of others have wanted to manage my assets and when we sit down and do an apples to apples 5 year return evaluation they can’t beat my returns. since I dealt with people from over 110 countries worldwide, I learned that is always easier with OPM ( others people money). Anyway, on my car we are going to do a leak down, compression test, and reruns the cam deviations, fuel trims, plus pull the plugs to make a fair evaluation of the condition of the engine. It runs great feels strong, accelerates hard and I’m approaching 7,000 miles of ownership. Just want to know where I stand at with this motor, and again I ain’t going to track it, I’ll take it supersonic every chance I get.

Managing the money over the engind repair.
Like I said you do whatever you want to do. I’ll make a decision, post the results and let the gallery decide. At the end of the day is whoever owns the particular car decision. Remember I had engine builder racing experience, engine lab testing, tearing apart motors and ratting them for deposits, sludge , ash whatever the parameter where. Yes I’m not an M96/M97 engine expert. I have my basics covered.

One of these days, we will need to update the spreadsheet that originated a few years ago about rebuild options. More shops are coming out of the woodwork offering various options for lots of situations, and there are plenty of situations, including get it running and sell it. Certainly not my choice as a seller or buyer.
Quite frankly, there are more options today than ever.

Thanks for the update
that’s a good result and makes me feel like I’m in excellent shape. With taxes and what work I have done to my car I’m at less than 20k. It’s a coupe with 408s . Anyway, we just don’t know what was done to my engine. It’s running top notch , squirrel 🐿 hook it up to the durametric Saturday and everything is great. We believe by the mileage definitely at least the chain pads etc were already done. The IMs, rear main and clutch were done like 33000 miles ago.

Flat 6 Innovations gets reports of these types of failures daily. That's why Jake strongly recommends getting a pre-purchase inspection. The 996 is still the best 911 value, but at 22+ years old, inspecting the engine is vital with any purchase. And, I'm not talking about popping the rear deck lid and pointing a flash light into the engine bay. I'm talking about checking camshaft deviations, rough running index, over-rev report, readiness status, manometer test, fuel trim, sump inspection and even scoping the cylinders.
OP, sorry for the loss. Sucks. You're not alone. Happens a lot. Unfortunately.

Found a couple or relevant posts from other threads that are worth adding to this thread:
And then the one that puts it all into perspective about PPIs and the current market:
Work_truck makes a great point about how it's difficult to even get a seller to do a PPI in today's market given the demand.
What you should look for when buying a 996:
From GC996
Here are the big issues and easy solutions that can help prevent engine failure.
1. Intermediate Shaft Bearing Failure - Replace with either IMS Retro or IMS Solution.
2. Water Pump Fan Blade Shattering - Replace with new water pump.
3. Bore Scoring - Change your oil at least 2X a year. There are other things you can do but IMHO the biggie is change your freeking oil often. You show me a garage queen with 60k miles and I will show you a car that most likely had only 4 oil changes in 20 years. This is the main culprit of bore scoring which is then amplified by bad gas, low oil levels, bad fuel injectors, starting the car with bad oil and low oil levels in sub-zero weather.
4. AOS Failure - Replace with UAOS.
There are other issues that are track related such as oil starvation/oil pressure stability and the need for more oil and water cooling, but these just like the 4 issues above are easily preventable with the right bolt-on parts.
So all you gotta do is find a car you like and...
1. Make sure it has all its service records so you can see if the previous owners did the service they were supposed to, and how many oil changes its has. If there are no records, run away.
2. Have a Porsche shop that knows what it's doing perform a thorough PPI. This will tell you the condition of all the parts. If no PPI, then run.
3. Have the same shop perform a borescope from the spark plugs and from the bottom of the sump. This will tell you if you have bore scoring. If no borescope then run.

With regards to PPI, remember as you're gearing up to spend $2,000 to have your sump dropped and your bores scoped that there are probably 5 other buyers ready to buy without that due diligence.

Thanks for the words of encouragement. I originally bought my 996 C2 from the money I got from my stolen BMW S1000RR (back when prices were reasonable for 996s). While I have always been interested in sports cars and followed the scene very closely, when it came to ownership, I always saw motorcycles as a better value proposition for the experience I was looking for. My time driving my 996 and various other 996s, 987s, 997s has really opened my eyes about future Porsche ownership. It was a heck of a journey for the two+ years I owned it. I racked up about 6K Miles and definitely never babied it. I also leveled up my gear wrenching skills considerably which can be carried over to other aspects in my life. I'm out of the game for now and will be back on two wheels for my next "for the weekend" purchase. However, I feel my hiatus from Porsches is only temporary and I see myself sitting behind the wheel of a now dying breed of NA 911s or a Cayman in the near future.
