Help removing Exhaust housing?

[JDSfastGN]

I have a turbonetics .82 housing waiting to go on my PTE44 for a little more topend but I'm stuck. i can not for the life of me get this old housing off. I definitely don't want to hurt the turbo at all. I've WD40ed it, all the bolts are loose, but it just won't come off the turbo or even clock so I can get the other 2 bolts fully out (the ones near the oil feed and return ) I've tried an air hammer and really uglied up the current exhaust housing and as a last resort I put it in the oven for an hour at 325* and still no luck. any ideas? And what can I expect to pay a turbo shop to remove it for me if I can't get this?

You baked your Turbo

We had a tough time with mine also....we sprayed it, beat it with a rubber mallet, pried it, etc. We ended up making a puller for it, slowly we worked it and it came off...

Good Luck

P.S. Make sure the two bolt's you cannot get out are loose and not hitting,Make sure that is not the cause of why the Turbo will not split.

Take a torch and heat it up. If you don't have a torch get one of those butane/propane torches that plumbers use to sweat fittings...It's carbon that has a hold of it.

Scott is right, when we finally got my apart there was a ridge of carbon I had to sand down

How about GM Top Engine Cleaner and soak that end of the turbo in it. It will clean piston tops overnight in a small bowl. Should cut turbo soot quick!
