Also, changed the IMS bearing to an LN product, clutch and rms 5,000 miles ago so I can exclude that.

Just wanted a gut check (or ear check) before I start tearing into it and diagnosing things that you�re all hearing something unusual here as well.

Hi everyone, I recently changed my oil (M1 0w-40) on my 1999 996 with 80,000 miles in it and added a bottle of ceretec, just to try out.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

2 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

Hi everyone, I recently changed my oil (M1 0w-40) on my 1999 996 with 80,000 miles in it and added a bottle of ceretec, just to try out. I have some �clatter� at start up which I feel is pretty normal, but wanted to see if the ceretec would help. It seems to have helped a little as it�s quieter at startup, but now I hear a new noise. Not sure if I�m just being hypersensitive because I�m listening for for subtle changes or if there is a real issue. Also, changed the IMS bearing to an LN product, clutch and rms 5,000 miles ago so I can exclude that. Here�s a quick video... hopefully the sound comes through. Almost sounds like something on the accessory circuit vs the engine because it�s not in sync with the engine Rpms. Water pump? Tensioner? Lifters? Bore scoring? Piston slap? Catastrophic rod knock... Or is it all in my head? Just wanted a gut check (or ear check) before I start tearing into it and diagnosing things that you�re all hearing something unusual here as well. Thanks for listening!

POST 2Original post

I don�t hear it over the noise of the alternator and/or secondary air pump. Can you take another video under the car and try to get as close to the noise as you can?
