It worked great on my '08 BMW X5 3.0i (E70). This part saved me the expense of replacing the entire valve cover.
First, I watched some YouTube videos to get a feel for the task at hand. Then I removed bthe plastic engine cover, cabin filter, cross brace, and two coils from back two spark plugs... to get good access to the old PCV valve. Then, I used a paint removal electric heat gun to heat the old part for several minutes in order to free the adhesive. Next used a large screwdriver to pry up on old one usig the valve cover as a fulcrum, and it finally popped off. I was careful to save the old spring for reuse on new part. I cleaned the joint area with carb cleaner and sand paper, making sure that all old adhesive was off the valve cover interface and made sure that the surface was smooth I test fitted the new part several times until right. Then, I used a 2 part epoxy and spread it evenly around the seat of new PCV unit and after positioning the spring I seated the new part firmly on the valve cover, tapping it down gently with the handle of the screwdriver, makingsure that it was seated all the way down. I let it sit and cure overnight. I reassembled everything else the next morning and tested it out. Engine ran great, and no more loud squealing noise.
After inspecting the old diaphragm, I found it to be cracked, which was causing the squealing problem.
Very satisfied. Took me a few hours, but this job saved me at least $1K in parts and labor.
