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.

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

Wondering if anyone here knows the measurements and wear limits for intake and exhaust valves and guides? Mine seem loose and the add oil then stick finger on top of guide while pulling valve out produces little suction. The only thing I've been able to find are the dimensions of the exhaust valve guides which are 6x10.58x43mm. I've also read that exhaust valve guides can be used for intake valves by shortening by 0.1 inch (2.54mm.) https://eeuroparts.com/product/canyon/V996451 Car was not smoking when running.
