The white smoke alone is a good indication that you have a leaking headgasket. Also this type of repair requires you buying special tools and that alone could cost you minimum $500.00
You can do most of the work from the top but it is a very complicated procedure. The cam cover holds the cams in place so you need the special tool to press the cam cover back down on the cams. Also you need to have an organizer for the tappets because they all need to go in the same spot. Each tappet is a different thickness to allow for valve clearance. Also you need to have the special tool to lock the cams in place to remove the cvvt hub and install it. There is no guide pin to install the hub and you will need your friends to be familiar with installing and aligning the cvvt hub. When you have the head out, send it out to a machine shop to check for any cracks and warpage. Most likely your leak is at #2 cylinder where the misfire is happening. I really recommend you take it in to a shop for a big repair like this one. But if you are willing to do this repair then get a repair manuel or see if a Volvo tech will be willing to print out the removal and installation instructions. Also if the head needs to be replaced then you will need another special tool to check and adjust the valve clearance. Good luck to you and if you need any help just send me a message.
