Why is my Volvo 850 camshaft sensor leaking?

your rear camshaft seals are old...they are about 15 dollars at your local dealer. replacing them is a pain. like two to three hours worth of work...well I am referencing my 94 85 turbo anyway....

buy the hanes or chilton's repair book and you should be able to do it yourself.

Dealer price? 400 dollars plus mostly labor money...
