Hello all,
Ive been visiting this site for years and years ever since Wayne introduced himself on Porsche Pete's many years ago...tremendously useful and a huge asst to the porsche DIYer. Thanks

I need a little help diagnosing a problem with my 98 boxster. 78k miles. regular oil changes at 3000 miles since I bought it new.

For the past two summers (I store it in our michigan winters) my car has let out a nasty rattle noise at cold start up only. Lasts a split second then all is normal. Drives fine. When it began i thought it was my starter solenoid sticking but it has gotten louder and a little longer in duration this year. Defintaly not a starter. Either chain tensioner or? It used to happen only if thr car sat for a few days, then last year after sitting over night. Now whenever its cold, sometimes even if I ran it earlier the same day. I have read everything I can find about it including replacing the tensioners as outlined in Waynes book. I also switche to a thicker oil without luck. I also found some tiny pieces of brown plastic in my last oil change (chain tenstioner slippers).
I have a recording of the sound which I think will be diagnostic when heard by the right person....but I cant figure out how to upload it!!?? The attachment icon (paper clip) is grayed out...

Any help would be greatly appreciated.

Thanks!
