Read evidence and context

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.

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

POST 1 / ORIGINAL POSTEROriginal post

Hi, registered here since have some troubles with my carrera. Year ago I had a engine fault first cylinder blew up and its piston little bit bended. Diagnosis - hydroblow. Installed new pistons, new rings, new gaskets - engine started, after mechanic noticed oil smoke. Disassmebled engine again and found 200 ml of oil in first cylinder. Measured compression - 20 in all cylinders sounds good. Logically if oil comes to collector its the easyest way to leak exactly to 1st cylinder, but where it might come from? EGR? Theoretically we can remove it/block it. What else might be the reason?
