Stripping the front of my car currently as it's a write off, and after taking out the rad, I noticed the left side of the cam casing was cracked and underneath what appears to be broken plastic pulleys. [pictured]
How can I check what other damage is done if any?

 

probably got a few bent valves...

 

take engine out and remove heads to check for more damage, probably vales, valve guides.

 

Thanks.

The engine will be coming out providing parts from it are salvageable but I won't be stripping it down or removing the heads.
What's it worth in it's current state.

TBH, it's not worth a great deal if it has bent valves. - Ideally big-end shells need replacing after this type of failiure, as when the piston hits valves, it tends to 'squash' the shells, and more than likely causing a bottom end failiure in the not too distant future.
