I don't remember the exhaust manifold connection from the rear giving me such a fit the last time I had it out. Seems like the clamp is stuck or something, any tips on getting that sucker off!!!!
Take the nut all the way off the clamp and remove the clamp completely. Works better if you spray some penetrating oil around it first and let it penetrate a little bit
What not to do when disassembling turbo - DO NOT forget to take the base off of the turbing housing before trying to tap out the shaft/turbine wheel assembly, doing so will result in damage to the turbine wheel and will make you feel REALLY stoopid.
