Warning Hidden Problem on all 993's
I did an oil change today on my 993.
Everything was fine until I was on my tenth quart of Mobil 1.
As I looked down the oil filler spout with a flashlight,
I noticed little bits of plastic stuck to the sides.
I put my finger in there and pulled on the plastic cap that holds a spring
only to find the spring had a plastic cover on it that had deteriorated and had gone into the oil.
I have no idea what this spring does but I'm not putting it back in there.
If someone knows please tell us!
This is my 11th 911 and I do all my own work but I have never come across this before.
I see this as a major potential problem so be sure to check yours before it's too late.
Tomorrow I'm going to do another oil change and I'm going to cut the filters open to see what I may find.
I'm also going to cut the old filters to see if there's anything in there too.
The photo shows clearly what I'm talking about.

Yikes!
That looks like the fill bellows has disintegrated.
It is designed to pull out and flex, making the oil fill easier.
On two of my cars it has been removed. Now I know why.
There may be some particles in the oil tank as well.
That is not good.
Many thanks for posting.

Thanks for the heads up! I have never noticed anything of the sort when filling my 95 but I will certainly double check with a flashlight as suggested. Hopefully it's already been removed!

Mine just cracked last weekend. I usually place a rag under the filler opening to catch overflowint oil but this one time I didn't. I pulled the bellow and began filling. At some point I noticed I had placed half the oil onto the valve covers because the bellow cracked half way through.
Cost was 20.- for a replacement + 1 hour of cleaning up the valve covers.
I considered leaving it out and use a funnel but decided against it.
Just don't forget that rag

Not really, Just look down your filler tube with a flashlight. It's right there about 2" down. If you put your finger in you can just pull on the circular plastic and it snaps off. Then the spring and the bottom cap follows.
If this spring tube is deteriorated, it will spread in your oil very quickly.
After working on 911's since the 70's this has to be the worst mistake the engineers made in choosing a material to use in the most important and very critical part, the bloodline of our cars.
