83 300D

i was well on my way to replacing my injector nozzles when i got to the actual removal of the injectors. they will NOT budge! the whole engine moves i'm pulling so hard but nothing is happening.

can i spray some pb blaster around them? do i just need to get a bigger breaker bar and yank at it some more? i need to be cautious of catastrophe but i also have limited time to get this done this weekend.

is it safe to assume, because of how hard this is, that i will definitely be needing a vise to take the injectors apart? i was hoping to just use two wrenches as i don't have a vise...
