Got this from tdi forum
Quote"STOOOOOPPPPPP!!!! You pitched the turbo is my bet. You are just damaging the rods and bending valves by attempting to turn it over any more.
First, check the oil level. Low? Bad news.
Second, pull the upper intercooler pipe from the intake. A bunch of oil in it? Bad news.
Third, Pull the glow plugs out so you can relieve the cylinder pressure.
Fourth, if oil in everything replace the turbo once you look at the fins on the compressor side to see the amount of damage. You'll have to crank the engine over a few times to blow the oil out. Make sure you REALLY cover the holes as the compression will blow out the oil with TREMENDOUS force. You might want to possibly pull the pan to see if any rods are bent too."
I will try to do this over the weekend and see what I find Thank -you for your responses
