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.

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 2 / ORIGINAL POSTEROriginal post

Thanks randeria, Might have to take you up on that offer mate. My PPI showed 158psi average across 6 (no deviations greater than 15psi between cylinders), and was stated as within "spec'. However with a 11.3:1 ratio you would think that it might be higher? See how you go and thanks in advance. Cheers Macca the Kiwi

POST 3 / ORIGINAL POSTEROriginal post

Hi Guys, The compression test on my 993 RS reads 158 psi average with lest than 15 psi deviation. The PPI says this is within manufacturers tolerances. How does this sound to other 993 RS owners? 9m - what are your thoughts? Cheers macca
