[...]would be good if there was a way around this, anyone know?
or will i just have to change IFS back to OLDIFS at the start and end of every function?[...]
Well, it depends. The following syntax affects the IFS only for the read command inside the while loop, so you don't need to worry/restore the previous value of IFS for the statements after the loop.

Code:
while IFS= ...

Sometimes it's convenient to force a sub-shell execution to avoid affecting the current shell environment, but it depends on what exactly you' re trying to achieve.

Please post the exact command(s)/output (just copy/paste) you' re getting.
