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.

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.

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

0 acknowledgements have no verified action link; they do not establish a repair result.

Hi guys, new to the forum. Has anyone ever had or heard of a spark plug been blown out of a cylinder head ?

POST 2Original post

:welcome: Wait for Demort to get online :success: :thumb:

POST 3 / ORIGINAL POSTEROriginal post

Thanks hope he can help, I can give him more detail if he has come across this in the past.

POST 4Original post

I remember there was a thread a while back where a member had this problem, get trawling the search function..

POST 5Original post

Ive seen it in the past but not on a Porsche . Has it taken the thread out ? Is the thread a helli coil ? .. this would explain a sudden blow out . The usual cause is it wasnt tightened up when replaced but as these get noisy way before it comes fully undone then its normally spotted before it blows out.

POST 6Original post

Ive had that but only ever once, entirely my fault as well!! Got interrupted servicing my wifes Beetle and thought id torqued them up, had obviously barely nipped one up and ten miles on it shot itself out!

POST 7 / ORIGINAL POSTEROriginal post
