D3 3.0 TDI engine/torque converter rattle

[SIMI]

Hello,

have D3 2006 3 L. TDI and have really loud sort of engine rattle, i know most of us going to say chain, but was listening very carefully and its coming at the bottom of the engine, sort of where engine joins with torque converter, changed that common problem cam tensioner on right hand bank, but just after that went to look where is the noise coming from. My opinion 3 possible things, either main chain, oil pump or torque converter, then you listening for noise from bonnet open end its sound rattly, but when its on the ramp and try to listen from underneath its very noisy. In the morning or when engine off for good few hours no noise for about max 5 min and then its starts to rattle. Any opinions lads?
