I have heard that not everything that ticks is bore scoring and then there is the theory that says change your oil often and drive it till it dies and then sell as a roller or do a rebuild at that stage

Buying it, using heavier oil, and waiting for the inevitable engine death is absolutely an option, just not a smart one in my opinion.

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.

It sounds like a ticking to me but I am still not sure about what are correct Porsche engine sounds

POST 1 / ORIGINAL POSTEROriginal post

Looking at a 996 with a friend. These are recordings from below the engine below the oil reservoir. It sounds like a ticking to me but I am still not sure about what are correct Porsche engine sounds Thanks You Tube

POST 2 / ORIGINAL POSTEROriginal post

Trying to insert video but not working

POST 3Original post

Yes sir, that is some piston slap going on. Others will opine shortly. Run away.

POST 4Original post

Yes, bore scoring. Would likely sound louder if the microphone was under bank 2.

POST 5Original post

Yeah not sure, but it doesn't sound right. Agree with Coop above. Place phone beneath exhaust headers on passenger side and record for 15-20 seconds.

POST 6 / ORIGINAL POSTEROriginal post

Unfortunately we left already so likely not able to get it today. Due to distancing we could not take it for a ride but I guess we will move on. It was a nice car though 2003 75K miles and very well taken care of. Owner had never heard of bore scoring and told us it was the belt rotating. Buddy got hooked with my 996 and he is on a quest. I wanted to sell him my Targa but he does not want a Targa. I love my Targa but am yearning for a 997.2. Kind of hard to shop for cars during Covid Thanks all

Yeah my belt doesn't sound remotely like that.

POST 8Original post

There are any number of videos out there with cars with obvious signs of bore scoring. If the worst is confirmed, then a rebuild is 5 figures. Then there's also the "while you're in there" costs. There's no such things as a cheap Porsche.

POST 9 / ORIGINAL POSTEROriginal post

Is there any other explanation for that sound. I have heard that not everything that ticks is bore scoring and then there is the theory that says change your oil often and drive it till it dies and then sell as a roller or do a rebuild at that stage He is only looking for 14K for the car and I am wondering if it is not bore scoring whether it might make a killer deal. Just trying to play the devils advocate

POST 10Original post

A well-kept 996 with 75K miles for $14K? The seller is fully aware of the engine issues. I have never heard of a "killer deal" when it comes to a 996 making weird engine noises. It's dying and will require $.

POST 11Original post

Buying it, using heavier oil, and waiting for the inevitable engine death is absolutely an option, just not a smart one in my opinion. Hadn�t heard the �its just the belt� explanation before, its usually �its just a lifter�.

POST 12 / ORIGINAL POSTEROriginal post

Thanks all, very helpful. I have convinced my buddy that we need to walk. Will keep looking

The explanation I've heard the due to the wear surface on the piston being compromised the piston "rocks" twice at the bottom of the stroke making the easily identifiable "ticking" sound. As wear continues the ticking gets louder and almost sounds like a rod knock. Ends up looking like this...ask me how I know...
