Any Better Options for Oil Separator Hoses
 

Two years ago I replaced the two oil separator hoses that sit on the back of the intake manifold (2002 4.4i).

While replacing my timing chain guides, VCG, and all of the coolant hoses, I noticed that these new hoses I bought just two years were extremely soft and on the verge of failure.

Is there a better and more permanent hose for this? Is there something special about these expensive hoses? I feel as though a pair of 3/4 radiator hoses would last longer. . . .geez!

Man that is awful to have only gotten 2 years out of a set of genuine BMW hoses. I might even be inclined to take them back to BMW since most of their parts fall under the 2 yr/24K miles warranty. I am not aware of any other alternative hoses for the oil separator.

All rubber hoses are not created equal. Oil can accelerate the degradation of rubber hose, faster from the inside. How fast depends on the strength and material of the hose. I have noticed that some here have complained about different hoses going. I don't recall which ones they were. Since I have not experienced that problem with OE hoses, if you didn't use OE hoses that could be the reason.

I didn't know about the 2year warranty. And yes, I did buy them from BMW. I may try some hydraulic hosing, or polyurethane. I've spent a small fortunate on hoses for this BMW.
