Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Discussions that contain suggestions: 1

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

Suggestion
I'd second the use of an ozone generator - but don't leave it running for a week with the windows closed - ozone can be damaging to plastics and particularly rubber components.

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.

4 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1Original post

Hello, new owner here. I’ve had my Cayman Base for 3 weeks now. I have scoured these forums and have yet found the answer to my question. Everyone knows the S engine is prone to bore score due to the coating coming off the piston and scraping the cylinder. The 2.7 has a smaller stroke, cast pistons and supposedly doesnt have bore score. my question is, is it confirmed that the 2.7 does not suffer bore score? Or is it just much more rare? the previous owner clearly neglected this car, I found out it was originally silver repainted red. Interior smells like a casino from how bad the smoking was and just overall abused. I am trying to fresh it all and bring the car to my standard and wanted to see if a 2.7 borescore should be a concern or not.

Welcome!!! I know Don will visit here and suggest you move this to the "New Member Intro" section My thoughts: 1. Don't care about bore scoring - I also have the 2.7 (2005) - based on my research before my purchase (I do not have statistics or hard evidence, which is good) 2.7 engines seem to be "safe / safer" so I am not going to lose sleep over it (no news is good news to me); i don't think anyone / Porsche can "confirm." 2. I would buy an ozone generator (see amazon ) to get rid of odor Good luck!

POST 3Original post

I watched this video from Porsche Club of America before purchasing my 987.1 2.7l: Go to 9:45 for the specific part on the 2.7l. They explain how bore scoring happens in the M97 engine, and how the 2.7l doesn’t have this issue. Bore scoring is an issue with cars in colder climates, but I also don’t think this is as common of an issue as the 3.4l, due to the same reasons in the video. I’m not 100% sure about that though.

And yes - I'll suggest the OP write an intro, with photos of his project Cayman , which he can update as he sorts it out with new photos. @Whozaka - please visit: New Member Introductions and tell us about you, your Cayman and post a few pics. I'd second the use of an ozone generator - but don't leave it running for a week with the windows closed - ozone can be damaging to plastics and particularly rubber components.
