Can this be possible?

Hi all I'm fairly new here and would like some advice if possible?



I recently brought a 2.2 DCi Espace 3 with a leaky injector washer! Well normally these can be a pain in the ****, but when I got to the injector in question after removing the air filter!



The problem is it seems not to have any bolts in it!! (After nicking my wifes makeup mirror) it's presently done almost 500-600 miles to get it home as didn't know about the lack of bolts but it not let go yet!



Now my question is can I just rotate the engine, or do I have to remove it?



Any other suggestion would be gratefully received



Thanks in advance.
