Strange sound after service + repair

Morning.
I've got a 94 Celica (2.2L).
I had it serviced about 2 weeks ago, and at the same time the rocker cover gasket was replaced due to a leak(s).
Since then the car has been making a strange sound, it almost sounds like air escaping from somewhere. It gets faster the more I rev the engine, and it seems to be getting louder. Its also louder when warm.
It sounds kind of like a tsu tsu tsu tsu tsu tsu sound.

Any ideas what it could be?

Perhaps a vacuum, intake or breather hose somewhere has come loose or has accidentally been forgotten about when reassembling things. Check for anything obviously loose or if you aren't confident, take it back to where it was serviced and ask them to look at it.

Check tightness of spark plugs
