om602 N/A injector removal - '86 190D
Looking to get my injectors serviced and am having a few issues getting the fuel injectors out on my normally aspirated 190D. Do you know if the entire intake needs to come off to get the best access to the injectors? I've got the 27mm socket to get on them but couldn't get enough leverage to make them budge without worries. Really don't want to break anything and they feel super tight. Any tips or suggestions are welcome.

They’re tight. Breaker bar should probably do the trick

Breaker bar and a 3" extension. Tall enough to clear the valve cover or intake manifold without busting your knuckles but not so tall that you risk breaking something or shearing something off.

Penatrating Oil sprayed around the threads (PB Blaster is sold out here at Home Depot, Kroil is supposed to work even better but I have no experience with it) and letting it soak several day.
I think the 602 Injectors are treaded into the prechamber retaining ring. If they are badly stuck in place there is some chance of loosening a prechamber retaining ring and you will need a special tool to tighten the prechamber retaining rings and a torque wrench that can go a lot higher then the torque if the Injectors to re-tighten the prechamber retainer rings. Injector torque 70-80 Nm and prechamber retaining ring torque of 150-180 Nm. So there is an advantage to making sure only the Injector comes out. Loosen the Injectors when the Engine is hot. You need at least a 1/2 inch drive and a breaker bar 2-3 feet long.
