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 performed work without a confirmed outcome: 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.

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.

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

POST 1 / ORIGINAL POSTEROriginal post

i posted a reply a couple of months ago saying how the cylinder liner had gone pourous causing my 996 to hydraulic, this however no longer seems to be the case! After nearly two months of looking for the probelm, it has been decided that the piston rings have gone on my 996. The bottom piston rings have gone inwards, therefore allowing oil to get past and into the cylinder, thus causing it to hydraulic. This is better news on my behalf as it was looking like being an engine replacement before hand. Has anybody else experienced this problem? Migration info. Legacy thread was 105774

POST 2Original post

Glad to hear it is not as bad as it possibly could have been. Any news on what the final bill will be? Migration info. Legacy thread was 105789

POST 3 / ORIGINAL POSTEROriginal post

i think the estimate is around £3000 mark, this is to replace all piston rings (6 pistons, 3 rings per piston) and labour. anybody had this work done before? the mechanic reckons its because the previos owner has used incorrect oil. After readinginto the cracked cylinder liner problems (of which there are thousands) i am very keen to prevent this. is there anything i can do to avoid it? regards a1damuk Migration info.
