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.

So I got a Cel telling me that a o2 sensor in my 2.7 Boxster was on its way out so I pulled it and replaced with a new one.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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 1 / ORIGINAL POSTEROriginal post

So I got a Cel telling me that a o2 sensor in my 2.7 Boxster was on its way out so I pulled it and replaced with a new one. Upon pulling it out I noticed that it was discolored and white as opposed to it being black like it should be. I have been losing some coolant but it has not been a large amount. No sludge in the oil filler tube. However, after reading up on the issue it appears that the buildup on the o2 was caused by something silicone based such as coolant. The engine has had no work done to it besides regular maintenance so I can't think of anything else that this could be besides coolant. I am not comforted by the fact that the 2.5-2.7 Boxster engines have about the same track record as the 3.4 911 engines. What do you think guys? Is my engine on its way out?

POST 2 / ORIGINAL POSTEROriginal post

opps, meant o2 sensor in the topic line. i was a little out of it last night.

POST 4 / ORIGINAL POSTEROriginal post

hmm, works for me. it is just a picture of an o2 sensor with a whiteish/greyish coating on the sensor tip. after doing some research I am convinced that it is ok as many have said that it is common to remove an old sensor and find that it is discolored.
