don_k Posted July 25, 2017 Share Posted July 25, 2017 (edited) I'm on the road and have a problem with oil weeping out of the filler pipe on the valve cover of my 2000 R1100RT. I am nowhere near a BMW dealership. I will have to get a replacement for the o-ring that seals this part against the valve cover at an auto parts store. I looked up the part on MaxBMW.com's parts fiche. The BMW part # is 11 14 1 340 901. But it doesn't say what size it is. Can anyone tell me the diameter and thickness of this o-ring? Also, if there is a general automotive brand known for handling high heat I'd like to know that also as I believe it is the heat of the valve cover that deteriorates this o-ring (from what I've been reading last night and today). Thanks in advance. Don Kramber Edited July 25, 2017 by don_k Link to comment
Michaelr11 Posted July 25, 2017 Share Posted July 25, 2017 There are two O-rings that seal the oil fill there. One on the cap and another on the plastic sleeve the cap fits into. As a temporary fix (maybe), try taking the O-ring off the cap and flipping it over. Take the O-ring into a NAPA or Carquest type of place, not the standard retail auto parts store and show them the O-ring. They probably have a box of a variety of sizes and might have a replacement of the same size. The O-ring for the cap, from the Max BMW Fiche: 11 14 1 340 902 O-RING - 18X4 (that's mm not inch) Link to comment
Jim Moore Posted July 25, 2017 Share Posted July 25, 2017 (edited) It's a #214 o-ring. If you can get one made of viton, do it. Edit to add: I have a bag full of them in the garage. Can I mail one to you somewhere along the way? Donate $5 to your favorite charity and I'll get it in the mail today. Edited July 25, 2017 by Glenn Reed Link to comment
