It was out of state, but I had done my homework and learned about IMS, RMS, AOS, bore scoring issues, and talked to a local mechanic who inspected the car and seemed to be aware of those issues as well.

In retrospect, I believe that is true, and that the local mechanic who inspected the car was friendly with the seller.

I'm on the same dilemma as you and hopping to make the right decisions I'm inclining in to buy a short block from porsche and use my original heads.

Suggestion
Installing a spin on oil filter with no bypass could potentially save the crank and cam journals, if you decide to rebuild instead of using a new short block.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

After years of planning and hard work, I recently fulfilled a lifelong dream purchased a '99 Carrera coupe with 71k miles. It was out of state, but I had done my homework and learned about IMS, RMS, AOS, bore scoring issues, and talked to a local mechanic who inspected the car and seemed to be aware of those issues as well.
When I picked up the car, it wasn�t making any worrying noises, but just a couple weeks after bringing it home I heard a ticking sound at startup that would fade away. I took it a local Porsche specialist that looked into the cylinders with a borescope and confirmed scoring on cylinders 5 and 6.
As I understand it, the only fix is to bore-out and resleeve the block - basically a complete rebuild.

As I understand it, the only fix is to bore-out and resleeve the block - basically a complete rebuild. I�ve talked to 4 different Porsche specialist shops, and searched the internet, and can�t find a number lower than $15k to fix this. The dream is now a nightmare. That�s almost what I paid for the car a month ago, and I�m having a tough time justifying spending $30k+ on a car that will likely end up being worth low 20s.
I have two questions for this forum:
1. Is there a way to fix this car for significantly less than $15k (doing the work myself is not an option.
How much is the car worth in this condition?

I swear this site is making me skittish. Like the OP, I bought mine after doing my homework. To get a through PPI you have to pay a lot, and many places will just not do it. I guess they don’t want the liability. I have been discovering issues with mine that the seller did not disclose or just lied about. Nothing I can do now (buyer beware). However, today I just started the car and was planning a short drive and I swear I heard the engine slightly ticking for about 10 seconds as I started it. Now I am worried about scoring on top of my IMS bearing, AOS, and RS. Ugh....I haven’t fragile garage queen. Lol.
I intended to post in the other thread, before I accidentally deleted it, that the seller probably knew about the bore scoring and did not disclose it. The OP stated that he discovered it shortly after purchase. Bore scoring is not that common in the 3.4. I don't worry about it. Unfortunately for the OP, he will eventually have to do something about it. I would fill it with 15W50 and drive it until it starts burning a quart of oil every 1000 miles. Installing a spin on oil filter with no bypass could potentially save the crank and cam journals, if you decide to rebuild instead of using a new short block.
Thats bull****, if they colluded to screw you I would be down there kicking the crap out of the owner, and then the mechanic. If you could prove that you may have a case and could sure them for the amount of a new engine, or your money back? Subpoena the mechanics records of the car lol. My question is why would you have a mechanic friendly with the seller perform the PPI?
Thoughts and prayers to you and your wallet. I went through a similar situation and opted for a full rebuild. Best of luck with whatever you decide to do.
