Help needed!

This is the condition of my A4 2007 engine, since yesterday ...

Two months ago i had an incident in a flooded road, water entered the engine...

Driving conditions were always normal, up to 4000 rpm max.

Is this due to water?

Has anyone any idea why the engine base cracked?

 

I did a little recearch since my last post.
It seems that 2 months ago i hydrolocked the engine.
The thing is that the engine was cleared and flushed with chemicals, by an authorised audi garage.
Is it possible that water or chemicals trapped in the combastion chamber?
And if that is the case why the engine block cracked nearly 2 months later?
Please help!!!!!!!!!!!

Looks to me like the oil pan rather than the block. I would be concerned of foreign materials being all throughout the engine.

You haven't bottomed out the car recently, have you?

 

you should not have had it chemically cleaned im pretty sure your model has an aluminum block should always be cleaned with a dry brush maybe slightly dampened.

i would go ahead and guess the guys who "cleaned your engine" did not remove the chemicals properly they mixed with the oil and heated up thus causing the material to crack.

if you can take samples "scrapings" from the inner area on a razor blade and take it to any type of lab and ask for a chemical analysis they will be able to tell you what chemicals (if any) caused the break. After you get the report causually ask the mechanic what he used to clean your engine as him to itamize a recipt then come back and threten a law suit if you find they are at fault.
