Hey guys I am in the middle of swapping turbos and thought i would swap some gaskets while i was at it. I am having a hell of a time trying to get the whole turbo return gasket (return line to the block) off. I have tried using a single sided razor and soaking with a penetrating spray. The engine is still in the car but i did remove the exhaust manifold to replace the gasket and make more room. Which was a good thing because apparently it was leaking at the 4-5 cylinders. What have you guys done to completely remove this gasket?
