My skoda octavia mk2 threw rod from oil samp

Hello guys.  I have skoda laura  ( Octavia mk2) 

Firstly, in our india  skoda octavia mk2 is named as skoda laura.

We have laura 2008 model TDI 1.9 PD Manual transmission.

It covered about 130k kilometers in odo meter.

Once my car started giving too white smoke and few oil leaks on standing at cold start after a long journey before this happened.  Local skoda dealers said that  bad injector is reason.

After somedays  i had given some throttle/ accelerated on still 5min  cold start and at 3500 rpm out of 5k   a sound comes and engine get dead immediately. And all oil get leaked. 

We found 2 holes in oil samp not in engine block. And we put inside a camera in oil samp without opening it. Here some pics....

I think only my oil samp have 2 holes not in block. But it is required to change block of engine? Or not?   I didn't find any holes or crack in block from outside. But bosch mechanic refuses to open my engine or he didn't want to repair. He just said us to order full engine block and fix it. 

How he judged that block break and change it? Without opening?

But in my way im not rich. So there is any way to fix old block. There is no break  from outside.  I didn't find any brocken rod in oil samp. Just found some small pieces.

Let me know does we fix block? Or change ?
