Subject: Removing balancer shaft chain on 9000 turbo

Symptom:Very loud whining whirring noises from timing chain area of 1995 Saab 9000 turbo automatic.At first,noise seemed to be coming from auto box,(yeah...really),so I pulled the transmission.Stripped,cut open convertor,no problems.Ran engine with box out of car,and noise is still there,but less severe.It seems with the box on,the resonances from the flex plate are worse.Box is now back in car. Pulled cam cover,and,as far as I can tell,timing chain is OK.Probably it's balance shaft chain.Car is UK 2 litre.Definitely has balance shafts.. What's the easiest way of pulling the timing cover? I don't want to remove the head if possible,already spent way too long on this job.Can I drop the sump a bit,and wangle it out,with the head still on? Thanks :-) -- Best Regards, Chris Wilson
