So found the two bolts on the turbo oil drain pipe that goes from the turbo to the oil pan, So two things where can I get stronger bolts? and how is the safest way to get them out? I was thinking This

 

are you referring to the two bolts that hold the turbo oil return line to the turbo? Those should either be a hex or torx head so the safest way to remove is to hit with some PB Blaster and soak for a while then use the right tool that fits the head - ie a hex bit or a torx bit on a socket wrench (not sure which it is - I haven't looked at my 850's in years). Not sure why you'd want stronger bolts - just buy some replacements if the old ones are scored up from a prior misuse of tools (Volvo likes to use torx - a pain but still better than those triple squares on older Audis!) Usually its the paper gasket that causes the leaks not how tight the bolts are :-)

 

^^ Good advice. There is no reason to get stronger bolts, just get bolts that are easier to work with. The drain pipe just sits there and lets oil return to the engine. There is no load.
