Nissan 350z secondary timing chain tensioner wont compress

Hello i am working on some timing work on my 2008 350z
touring. The tensioner on the passenger side cam timing
assembly wont compress. The drivers side will easily
compress down, i can use 1 finger and it will compress all
the way down. The other side i will push down with lots of
force and it will barely even budge, and after it does move
down just slightlyyy it wont budge at all. I would really not
like to remove the tensioner as i am pretty inexperienced in
engine work, and with the tensioner being stuck all the way
out it will be a huge pain to slide the chain off because you
have to remove the chain, and gears to even get to the
tensioner. I'm already suprised ive made it as far as i have
without breaking anything. But i also realize that timing is
something you want go be extra cautious.
Does anyone know if there's anything i can do to get the
tensioner unstuck?
Would it be fine to leave alone because its stuck out so it
will keep the chain tension?(i know it probably wont but
cant hurt to ask).
If i do have to replace for the tensioner how will i get the
chain off with the tensioner all the way out, its already hard
enough to get the chain off with the tensioner all the way
compressed.
Any help is appreciated! I apologise for any stupid
questions.
