I've got a big leak on the pulley/belt side. That's the front mainseal? I will probably have an independent garage/Alfa specialist do the repair, but I do have the option of renting a lift in the garage and doing it myself. Can anyone give an estimate of how many hours the garage is likely to bill for the repair? How difficult is the job to do myself? I'm able to do many repairs myself, but I've never tackled something like this.
