Do these require adding oil to the strut housing ?

I believe D. Clay has those shocks.  He'll give you first-hand knowledge.

Do these require adding oil to the strut housing ?

I cant remember where i read this, and just looked for it again without luck..

If it's an Bilstein Upside down construction it's my understanding that it's recomended against adding oil to the strut housing, as the shock seals are contained inside the strut, and the oil could damage the rubber in those seals.

The upsidedown construction can be considered like an ordinary shock except that it's the bottom that sticks out , usually this is very thick to acomodate the valving. And the strut is sealed with a large screw with a rubberseal.

In other words, the piston is fixed inside the strut, and the cylinder is what moves in relation to the piston.

Where on a standard design its the other way around.

Hope to help..

My struts were oil coated on the inside but I didn't add any oil. I did put anti-sieze on the collar nuts.

This exact same discussion just reached a pretty inconclusive conclusion (?) on Bimmerforums:

The right answer seems to be...ask Bilstein and let us know what you find out.

Unfortunately I can't get ahold of Bilstein ,at least I haven't found a way to contact them. I have emailed Turner Motor Sport and asked them since they are a distributer of Bilstein.It seemed like a easy question.:confused:
I'll keep you posted .

I had to go to yellow book .com to get a number for bilstein in california.
I spoke to the installation guru and he said no oil required for the touring struts.
Alrighty Then
Case Closed

He came up with the same answer on Bimmerforums:  "I got ahold of Patrick at bav auto and he said No Oil Required with the touring struts.  Thanks everyone"
