porsche 996 noise on cold start

Hello,

 

 

After 5 minuets when the engine is warmed up that sound goes away and I hear this sound here like there is something is leaking:

 

 

 

Please comment and let me know what you guys think.

 

Thank you

The first video is the SAI pump. Needs lubrication or replacement. I can't hear the noise you're talking about in the second video.

Thank you very much I was worried it would was something else. I will look into how to lubricate it. I was even scared to drive it.

Hello Ahsai,

After some investigation I did find an air leak on the vacuum line and fixed which fixed everything and car runs great.

I also found out where the coolant is leaking from as attached in the picture. I just don’t think that’s the job I can do.

After hearing that I will have to drop the engine scared me off.

I will try to take it to a mechanic tomorrow and see how much they will quote me for it.

Your recommendations or comments are always welcome.

Peter

Yes, a lot of things need to be removed. You may also need to LOWER the engine (not dropping the engine). Support the engine bottom and remove the engine mount nuts, then you can lower the engine by a few inches and that creates all the space you need to work on top of the intake manifolds.

I'm not sure that oil leaking from what looks like the oil cooler would make that gurgling sound.

check out other threads on the forum.

How's the coolant level?  Have you put on the updated 997 reservoir cap?

glad you found the vacuum line leak.  Good luck.

The noise is from the SAI pump and I got that fixed just like what Ahsai mentioned. The post I added was from a coolant leak I found under my car.

It’s hard for me to do all that since I don’t have a garage, but thank you for the details. I took the car to reputable Porsche mechanic and they were very honest with me with decent price quotes. They have found more vacuum air leak and they are fixing that as well. I can’t wait to get the car back. I already missed it.
I also hope that I could have some peace after that for a while at least with no issues.
