Yes, but does that mean total rebuild or something a lot less expensive?

The term "rebuild" is really a dirty word here, it does not describe what we do in any way. "Rebuild" means take it apart, clean it up, fix the problem by using the same regimen and components that the factory used. That never happens here.

No matter the failure, at the minimum level this whole engine is coming apart to facilitate any repair.

You are right. Sorry, I'm an old Chevy guy. I keep forgetting this is a whole different world. Swapping blocks or heads (especially heads) was fairly common because it didn't add much to the cost. Plus, the big valve heads added quite a lot of performance. My gut feel is I don't really belong here.

Don't worry. I'm an old Ford guy. To me, for it to be called a "rebuild", almost everything EXCEPT for the block and heads should be replaced or machined. If I had a Dollar for every used car I looked at where the owner advertised that the engine had been rebuilt, then could only provide receipts for a new set of gaskets, I could retire.
As for the Bronz' car, Jake's posts are starting to read like a bad detective novel. Let's skip the teasers and cryptic references. It's ok if you don't post until there are actual findings from the teardown.![Wink](https://rennlist.com/forums/images/smilies/wink.gif)
And I hope Bronz does release Jake to tell us the whole story. I, for one, am extremely interested in what's going on in that engine.

It would be interesting to understand the root cause, especially as you may have seen this before. Is it an inherent weakness in the early 91a and something they all are potentially subject to? Or perhaps related to colder temps, oil weight and/or bore scoring? If I recall correctly the OP's car was from the south before moving to the colder north-midwest. We know there are many 997.2 on the forum with well over 100k so trying understand if this is just bad luck, owner maintenance or an engine design issue like the BMW M3s that needed to replace bearings proactively.

@sandwedge But it's all good, will be fixed better than new and has a clean Carfax, right?

My wager based on Jake’s latest comment (not said with any mirth or malice at all) is that either a valvetrain component wore out and got strewn all over the engine (scoring some bores and/or oil passages in the process) or that the new theory for why bore scoring disproportionately affects cold climate cars is the case here. This theory postulates that fuel injectors fail first resulting in poor fuel spray patterns that wash away the thin oil film between the pistons and cylinders leading to more scored bores. Now I just hope that we get to know the real diagnosis and some ways to try and prevent it from happening.
