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.

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

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

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

POST 1 / ORIGINAL POSTEROriginal post

cruising @ 75mph, check engine light started blinking, then the idling went rough and tapping noise from the left engine bay-- turned if off and had it towed.. car has 18k miles . owned it less than 2 months. My first porsche. 1999 coupe 996 with tip

POST 2Original post

Loud tapping noise from one side of the engine typically indicates is the hydraulic lifters. Either the oil passage that supplies the oil is clogged or the hydraulic lifter's seal has failed causing it to fail.

POST 3Original post

Find out what code the computer threw. The tapping you hear may be an electrical snapping causing misfire.

POST 4 / ORIGINAL POSTEROriginal post

thankyou so much for the rapid replies-- It's in the dealership-- they just asked for me to authorize a diagnostics test-- to drain oil and pull plugs...3 hrs OUCH! It's like waiting for the surgeons report on that grapefruit size tumor they found beside your left ********!!

POST 5 / ORIGINAL POSTEROriginal post

OIL TUBES CLOGGED-- tubes cleaned, oil changed, lights reset and away we go~~~~

POST 6Original post

congrats on the good news. Now, to prevent this from ever happening again, you need to start driving the car harder so that the oil tubes have no chance of clogging...

POST 7Original post

the harder you drive it, the happier you, and it are! jonny law dosent take too kindly to it though

POST 8Original post

i have the tapping noise its nothing its just the purge valve in the emissons system im not fixing it since i don't care about emissions. it does nothing to the performance and the only side effect is a bad idle sometimes. the purge valve is fine in my car its just doing its job (which is why it sometime does the annoying tapping noise) its just that i have a leak in my emissons system somewhere.
