Chirruping noise on starting Saab 9-3 - Northern Ken
My 1998 Saab 9-3 2.0l non turbo has developed a strange chirrup/high pitched squeak when starting which vanishes after approx. one second. The timing chains are quiet, it runs with 10w40 semi-synthetic oil and a Saab oil filter. It has only done 72000 miles and is used for a 30 mile round trip every couple of days - no short runs at all.

The noise seems to be coming from directly underneath the rocker cover at the end where the sprocket to drive the front camshaft is.

Any ideas before I start dismantling it at the weekend to have a look?

Could be coming from the drive belts for fan, alternator, steering pump etc.
