In the morning

Recommended Posts

Almost everymorning when I start my 1999 Carrera 996, I hear this rattling noise, it sounds like chains or something like that, Are the Variocam chains and tensioners a maintenance item that need to be replaced, My car is now 76,000 miles and runs very good, I track the car about 8-10 times per year any sugestions on what this sound is, it only happens when I first start the car in the morning, any subsequent starts are fine.

It is the oil pressure building up in the lifters. I get it as well, I just turned 91 K miles last week on an 01 996.

Depends on the sound I would think. I have a slight ticking noise and so does a friends 993. After a little while the lifters fill with oil (pump up) and the noise goes away. My friends 993 noise remains (lifter going bad). However, to me, a rattling sound is different than a "ticking"noise I associate with a lifter. I wonder if the chain tensioner is going bad? I assume they pump up like they did on older 911s (after '76). That being said, chains will stretch and it is the job of the tensioner to take up this slack. Porsche says they last a lifetime but I don't buy that. After your out of warranty they don't really care how long it lasts. I have 99000 on my 2000 C2.

I was under the impression as posted here so many times that Mobil-1 0-40W was the correct oil for 996

Correct, that is the factory fill for the last several years.

Should I stay with the 0W-40 or should I go to another viscosity.

Stay with the 0W40.
