Om60x breather

[OM602Turbo]

I've pulled the crankcase cover of my OM602 Turbo engine because the breather diaphragm was leaking, it works like this, and the diaphragm has got the following part number A6010180033, Mercedes don't sell it anymore, I found one on autospares.lv but they aren't replying and want 50£ for postage.

I believe the diaphragm is the same on turbo and non turbo, 4, 5 and 6 cylinder engines.

Has anyone found a alternative, the diaphragm has a exterior diameter of 82mm

If I remember this engine was used in the w124, w140, w126, and sprinter T1 between 1993-1996.

Thanks in advance
