What to do? Drive the car and kick that can down the road. When investing in stocks and shares, one is only exposed to a loss when you sell an investment that is below the original investment amount. If you sell the car at a big discount you realise a loss. If you don’t and carry on driving the car you won’t be affecting its value, so my advice unless you need the cash is to hang on to it and enjoy.
Should you decide to hang on to it, read, read and read some more about this borescore. Fundamentally you want to understand what the various stages of Borescore are and what is the end game. Does borescore result in catastrophic engine failure for example, what is piston slap? Don’t limit your research to Porsche engines only (note, Cayenne’s, Macans, 991’s and Metzger engined cars also borescore) look at Subaru Boxer engines and other cars that live with piston slap.
I bought a 3.8S in summer - the owner, a wealthy individual, just slashed the price of the car and got rid. The car has sooty tail pipes, uses oil but no more than within the stated tolerances that Porsche set and it has faint tapping from bank 2. I plugged my Durametric to monitor the vital signs, like camshaft deviation - no issues, engine roughness - no issues, long term fuel trims - no issues, misfires - none. So far I’ve driven 1500 miles in the car since purchase, which is about the same mileage the previous owner covered in the previous 2 years.
Does this mean that the car is fine and dandy? No. It’ll need to be rebuilt at some stage or I’ll sell as is - until then I just keep a close eye on the oil consumption and carry a litre of oil with me at all times. I don’t track the car and follow the usual advice on warm up procedures. I also only use 99 Ron fuel; Tesco, Shell, Esso. I’ll open the car up at times to blow out the cobwebs but it’s getting more and more antisocial to rag cars in 2024 especially in and around London so the car is barely stretched these days.
In the end you’ll do what’s right for you and your circumstances. Good luck.
