Putting Turbo in oven?

Not as crazy as it sounds...
I have a TD05 turbo I want to take apart, unfortunately the big circlip that holds the compressor housing cover on is a little rusted and won't budge.
Can I safely put the turbo in the over to about 180 deg C? This is low enough not to affect aluminium heat treatment, but will it kill the seals etc? Normally the core is water cooled, but I don't know the temps involved in normal use.
Alternatively, does anyone have any goof suggestions on how to remove said clip.

my clip was mint....however, when removed, you will probably find the sections of housing are stuck proper too
would have thought seals will be ok, as even on a car, you cant touch the thing after driving, they can reach 800 degrees or more, even when cooled by the water.

Yes, will try again tonight, been busy on other things of late. I wouldn't mind cleaning up the turbine housing a little while it's off.
BTW Townend Garage supplied me with some water hoses and banjo bolts for just £10.

WD40 didn't help a great deal, but heating the cover with a blowlamp did the trick.
Just getting hot enough to release some of the grip on the clip, probably about 150'C as it hissed slightly when I touched it with a wet finger.
I stripped the whole lot down to check it out. Good job I did as the previous owner (of the turbo) obviousl had a piston go, as half of it was still in the turbo.
Bearings are all okay, seals are mostly metal on metal, only rubber ones being o-rings for main cover, and plate behind the compressor wheel.
I will get some pictures up together.
I might have a go at porting it a little, as there are plenty of casting flaws that can be removed.

naa, i don't think it quite warrants it yet. But now I know how to get the exhaust side off without disturbing the rest, I can do it any time. Need to get to my folks place, where the garage is equiped with mill, lathe, pillar drill, welder etc etc.
I think that will be done in conjunction with the "big job" which I am planning for next year, when I don't owe as much money. Head swap, pistons, rods, clutch, hybrid turbo.
I think 400hp should be the target for any self respecting estate car owner. (proper estate, not your impreza wagon stuff).

Out of interest, was the engine / turbo still working before you took it off ?
As with engine bits embedded in the turbo it would be massively out of balance
Please post some photos if you get the chance
