found a compression spring in my oil filter

[911-ST]

Hello,

I changed my oil today but while I removed the oil filter in order to change it a compression spring fell out. I don't know where it comes from
I looked at the technical drawing of Porsche but ... not really similar to my setting.

I have a 911 1970 2.2. if it help.

Am I missing some parts ?

That looks like a spring from the oil filter's bypass valve (built into the filter itself) - guess it fell out of the filter somehow.

Thanks for the swift reply
I could not find where it came from looking at Porsche drawings. "From the filter it self" is a good explanation for me.

Curious here....what brand of filter?

[911-ST]

BOSCH

Here it is.

Take off the oil console, take a look at the back. Make sure the spring is still there.

[911-ST]

yes it is.




It reminds me the movie "Le Man" when they drop some bolts in front of the Ferrari paddock.

Thanks!

while not statistically significant, that's enough of an issue for me to trash my remaining Bosch filter and stick with mahle filters going forward

I've been using Mahle oil filters exclusively except for one time only. That one time I used a Porsche branded oil filter and it leaked. I'm sticking with Mahle.
