We have a nasty oil leak in the VVT pulley on our Volvo V40. A quick search on the net brings up nothing. Would there be any place to get one other than the dealer?

 

Google volvo followed by the part number. Example: http://tinyurl.com/4o8q6a2 (no idea if this is the right part # for you its just an example)

Other than that, the most common places that I get my parts from and compare prices are:

http://www.eeuroparts.com/Main/Home.aspx
www.autohausaz.com
http://www.koperformance.com/
www.fcpgroton.com
www.myvolvopartsonline.com
www.swedishautoparts.com
www.partsgeek.com
www.amazon.com
www.rmeuropean.com
www.volvowholesaleparts.com
www.rockauto.com (probably not so much for the VVT though)

Just bang the Volvo P/N into their respective search and boom!
If you checkout the www.taurusclub.com fourms, theres usually a discount code posted for rockauto there somewhere.

Happy shopping!
