I am replacing the injectors in my 77 240d with rebuilt injectors bought from this site. After removing the old injectors I did not find any heat shields in the pre-chamber, or at least it seems there are none. There is certainly nothing that can be picked out using the little angle pick sent with the socket kit.
Is it possible that the car did not have heat shields? Or am I just not trying hard enough to get the old ones out?
Here is a link to a picture showing one of the pre-chambers. Can someone tell whether I am looking at the bottom of the chamber?
