By measuring how far the tensioner protrudes you can determine how badly the chain has stretched. I seem to recall that 9 mm is the chain replacement limit. I have 2 9000's, a '92 Turbo with ~90k miles and a '93 CSET with 120k miles. I had the head off the '93 for a headgasket and inspected the timing chains and sprockets and the chain was right at the wear limit so I put a new one on. The '92 was making a lot of chain noise so I pulled off the timing cover and found the chain tensioner was completely extended and the chain was still slapping around. Obviously the PO didn't take care of it quite as well as I do... I also inspected the sprockets on the '92 and found the crankshaft balance chain sprocket had worn teeth so I put a new one on along with a new balance chain. All the rest of the sprockets looked fine. I think the balance chain crank sprockets were a weak point on some of these earlier engines (91-92's) as I have read other accounts with the same problem. If left too long the balance chanin could be thrown which would take out the timing chain which would then bend the valves (rebuilt head time) YMMV, -Fred --- Outgoing mail is certified Virus Free.
