Thanks I've had a look at that thread about pcv valve so I best get it sorted out since I've been ignoring it for a while now . How much should a garage charge to replace it roughly?

No need to get a garage to replace it, it's literally a 30 second job: pop the old one off and pop the new one on.
Giving mine a clean fixed the squeaking noise, so I'd do this first. If that fails, replace the o rings around the bit that plugs into the manifold. Failing this then I'd replace it.
Here's the replacement part. (£36.25)
