Suggestions???

Hey guys I need a little info. I have a 95 Milli that is eating me out of house and home... I have replaced so many things lately that I am saying no more. The car now has problems with the the rear cylinder leaking oil around the valve stem seals. other than that the car is sound just needs a paint job. I want your thoughts whether to just sale the car or to try and recoop some of my money by parting it out. I don't mind to wait on getting my money, just wanted your thoughts.
