I have the car listed above 325xi E90. I replaced the valve cover gasket and I'm replacing the Eccentric shaft sensor seal that sits on the top of of the valve cover. I ordered the exact parts for the vehicle for the 3rd time now thinking maybe I purchased the wrong size. Every time I tried to put it on. It still wont fit. I have no luck on finding some resource online. By any chance you have any tips or recommend what I should do?

Thanks,
Sebastian

If this doesn't help, is the new sensor the same as the old one?
