Is it worthwhile to repair or replace the engine?

[Treeri]

Greetings, everyone.
A few months ago, my 2005 BMW E61 3.0 200 kW ceased functioning, and I am uncertain if it is worthwhile to repair the engine or to get a replacement from the market.
I suspected that my engine block cover gasket was either leaking or damaged. During aggressive acceleration, excessive pressure caused several fragile coolant pipes to rupture, resulting in coolant loss; however, normal driving did not lead to any failures or coolant leakage. The mechanic consistently asserted that the issue was unrelated to the block cover gasket, but I remain unconvinced. I entrusted my vehicle to a mechanic for diagnosis. He subsequently informed me that the situation had deteriorated; he discovered that the turbo vacuum pipes were disconnected. Upon reconnecting them, the engine began to rattle significantly while in motion, prompting him to shut off the vehicle. Following this, he was unable to restart the engine; it cranked but failed to ignite.

The situation seems unfavourable.

The engine rotates but fails to ignite. Do you believe it would be more advantageous to replace the engine?

Please do a trouble code scan.

I can do it in around three hours using Ista.
