Has anyone tried oil additive to restore valve stem seals?
as most of you aware about valve stem seals issue on v8 e60 engines this is a costly repair to replace them. has anyone tried any alternatives to fix it such as oil additives or different oil? I understand it is not permanent fix however if it works why not go for it. my 550i has this problem. I am looking to try LUBEGARD BIO/TECH any feedback about this product?

valvetronic is fine I have bad valve stem seals. LUBEGARD claim it can restore seals by softening rubber. there many pros and cons about additives I think I will give it a try

Problem with those products is that they soften every gasket, not just the ones you want them to. I wouldn't do it.

Yeah, there are some theories that the ridiculous 15K oil change intervals could contribute to seal problems. The V8s really need to go no further than 7500 on a change to at least help keep the problem at bay. There is a gentleman on the boards (BMWOEM1) that will change those valve stem seals out for $2500 if you can get the car to him in New York...
