Subject: Re: Do I have to change 2 chains and 4 gears inside my 1996SAAB9000AERO engine?

Hi, If you're not confident in the mechanic's diagnoses, seek a second opinion, but do it sooner rather than later. You have two chains, the timing chain and the counterbalance shafts' chain. Timing chain noise can be heard clearly at the top of the engine. Noise from the chain for the counterbalance shafts will seem to come from lower down in the 'chest' of the engine / timing chain cover. If the chains do need replacing this soon it would be prudent to replace the chain guides and inspect the tensioners for correct operation. I know its a lot of money, but its a lot less than having to pay for a new engine, which could be what you're faced with if the timing chain breaks or even just jumps. Good luck.
