I think there is about 67 steps to taking the head off and getting it back together im shure if you have a detaled problem some one will know your solution, now is a good time to replace lots of stuff that is hard to get to with the head on. when you take the turbo off check the housing for cracks, and wiggle the turbine to check for play, you dont want much. if you have the money get the turbo rebuilt. it will upgrade to a T04E.
here is a good start but look for all the gaskets in the top end including head gasket. the time it takes is up to you and your part delivery time it could take 3 days or a month. man im pissed i payed 145 bucks for my arps here is some for 90
