I'm not sure what gives. was a running car pulled into garage. 2001 audi tt engine code awp had a code for vvt failing to reach upper limit. I did timing belt kit and chain tensioner replacement. rolled engine over by hand afterward, all marks checked out so I pulled the tensioner pin and reassembled the front of the engine. tried to start it and the engine made a squeal and seized instantly. I believe the squeal was from the starter cause the engine didn't even make a quarter rotation. it is now locked in both directions. ill be stripping it back down to the timing belt when I have time, as of now not sure if its the top or bottom that is stuck and generally confused as to what happened.
