How hard is it to do seals on a turbo?

[Sweet6]

My 63E turbo smokes occassionaly. The turbo works prefect and only has about 8K miles on it. I was curious if I could redo the seals myself?

Thanks

Steve,

I've done a few in my day. I could help.

I'd have to go dig up the torque spec for servicing a Garret.
