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 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
In both the above cases I believe the companies concerned manufacture their own repair sleeves that fit inside the existing block.

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.

POST 1 / ORIGINAL POSTEROriginal post

A friend gave me a 1999 3.4 engine from a Carrera. The engine has a very small crack on one cylinder, but starts and runs fine for about 30 minutes. The rest of the engine is in great condition, it barely has 15k miles. I read about sleeving the block, but cannot find any good tech on this. Anyone with experience? Thanks!

POST 2Original post

Hi There are 2 companies that do this in the UK. You should find more details on the website. http://www.autofarm.co.uk/ http://www.hartech.org.uk/ The key technical person (Baz Hartech) from the second site posts regularly on the Pistonheads Porshe forum and is very well respected given his well informed balanced posts. In both the above cases I believe the companies concerned manufacture their own repair sleeves that fit inside the existing block. Thus, you'd need to ship the engine (or short engine) to them in the UK for repair. Rgds Jon
