Is draining/replacing the oil from the turbos necessary?
My car is in for service to replace the oil pan gasket. The mechanic recommended that I also have him drain out the old oil from the stock twins. Is this necessary?
The twins have over 100,000 miles on them. Thanks for any info/advice.

Thanks for the quick replies.
Apparently there was a misunderstanding. He said that there was also a leak on the right side of the car and that he had to drain the oil to replace a gasket on the twins also.
So I have two oil leaks, one from the pan, and apparently one from the turbos. I haven't seen any oil smoke, so hopefully it's just a gasket.

Beware!
So far as I remember the only places where oil typically leaks (externally) from the turbos are the oil inlets pipes, (2, each with a banjo bolt and copper washer), and the oill drain pipes, (2, each with a copper washer. I believe these are a very common cause of turbo oil leaks, (to the outside, versus internal leaks which come out as exhaust smoke). I've replaced all of these seals, (copper washers/banjo bolts without needing to drain the oil. Therefore I don't see why he needs to drain the engine oil (=turbo oil) to stop an external turbo oil leak. Sounds like he either doesn't know what he is doing or you're getting ripped off. Removing turbos/turbo gaskets can be very labor intensive, i.e. expensive.
Forum experts - please chime in and correct me if necessary. Maybe I'm missing something here.
You also need to be sure that the leak from the pan is really from the pan and not from the engine rear oil seal - it's sometimes not that easy to tell
Try somewhere else, ideally a rotary specialist.
Good luck!

Thanks again for all the info.
The mechanic calls it the "turbo drain gaskets." He only re-sealed the oil pan. I told him to wait on the turbos since they've got over 100,000 miles anyways and I'll probably be replacing them soon. I'll wait and see how bad the leak is.
