Suggestion · Original poster
Since buying it two years ago I have been taking all the recommended steps to stave off further damage, but know that the engine is on borrowed time.

If a shop is doing it add 4k - 5k to remove and replace the engine/transmission .
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.

Hi All,
I regretfully have to sell my 911 as I'm selling my house and moving to a condo. I am looking for valuation advice. It is a 2004 40 Jahre with 90K miles. It has been diagnosed with scoring in two cylinders, burns about a quart of oil every 600-700 miles, and has a tick in the engine noticeable at idle. No smoking yet, and still pulls strong. The interior is mint, the exterior very good with some stone chips in the hood and a dimple in the back bumper. OEM wheels with minor corrosion but look great. Has new Bilstein dampers, water pump, and fresh brakes & rotors. Since buying it two years ago I have been taking all the recommended steps to stave off further damage, but know that the engine is on borrowed time.
Question is, what's a reasonable asking price for the car? The value seems to be greater than that of a roller, but what interest would be there if I ask more than what a roller is worth?
One point of reference: 112k mile 40th Anniversary 2004 996 with blown IMS (needs full engine rebuild). Asking $15k. Seems a bit low to me, but it's been for sale since 7/29/24, though price may have been reduced recently.

My personal opinion is 12k - 15k . Why ? Because of the expense to rebuild the engine the right way . Nickie cylinders along with new pistons . All new bearings . No one in their right mind would rebuild and not replace the AOS . New water pump . New coolant tank while the engine is out . And on and on . Easily a 20k - 25k rebuild cost . If a shop is doing it add 4k - 5k to remove and replace the engine/transmission . Now you're at 24k - 30k for a quality rebuild assuming there are no surprises . Unfortunately it's not cheap to play in the Porsche sandbox.
You could swap in a standard 996 motor from a junk yard for probably $10k -$15k or so, and maybe even swap over the x51 components from the existing motor. But I doubt the car would fetch 40th Anniversary prices for a car with a junk yard motor, so hard to say if it would be worth it financially to do that. With a quality rebuild, you might have a better shot at those $40-$45 prices you see advertised, but after subtracting the cost of the rebuilt (maybe, $25 -$30k, IF you stay focused), you get right back to the asking price on the car above. I might be inclined to put it on an auction site and see if you get lucky -- a mechanic doing all his own work might be willing to pay a bit more and still end up with a bargain.
