Agr tdi start -14°C low compression due to bent connecting rods

Afrer turbo crash at high speed oil residues remained in IC. I forgot to clean it so after turbo replacement oil gots into cylinders - inreased compresion ratio and caued damage of connecting rod. This happened at aprx. 3000rpm at full trottle maybe 3 times because i didnt know whats happened and I was testing what going on.. Strange sound was realy annoying. Engine is now working without any problem, expect starts at low temperatures because of low compression on 2 and 3rd cylinders.
