Engine Squeaking!

My 197 engine has developed a slight squeaking. Noticed it when out of the car, sat idle.

Done 75,000 miles + cambelt, waterpump all changed.

Recently serviced, hopefully you guys maybe have some ideas?

Difficult without hearing I know, a video just doesnt pick the sound up at all :glare:

Cheers

Mine used to squeak when cold and idling, problem stopped after changing cambelt/aux belt/tensioners etc.

Had a few experts suggest it was the aux belt tensioner on mine.

that should be all changed with the cambelt etc
