Yes, try to get the chain back in time which may require removing the rocker arms to completely close the valves. Then put compressed air in the cylinders using a compression test gauge adapter to see if there are leaks and where they leak.

Worked on two 240D's with broken chains that broke the cam tower/supports but did not bend valves so removing the cylinder head wasn't necessary. Both ran again for a long time.

Good luck!!!
