After having a few problems with one of my motors with excess oil consumption, I have found a how to although its for a Supra the basics are the same:

Thread rope into the cylinder and then turn it clcokwise until resistance is felt, then use a Valve tool to remove the cotters and change the seal.
This could be a cheap fix if you think your Turbo is good but still have oil burning
