You can open up the valve cover to do at least a visual on the timing chain and determine whether it is stretched or worn. Take a good look at the TC tensioner to see if there is still play on the tensioner rod. Replacing the timing chain is not a job for the weekend mechanic. You don't act on suspicision. Plus it being a chain, is supposed to last. I know. My 94 CS has the chain slipped on the crankshaft at 105k miles. The reason it did was the TC sprocket walked on the crankshaft because the bolt holding the harmonic balancer, the balance chain sprocket and the TC sprocket wasn't tightened after a routine maintenance. Otherwise the chain and sprocket were like new. I opened it up after I got a 69k miles replacement engine installed. I wouldn't replace the chain at 130k miles just yet. Open the valve cover and take a peek first. Yaofeng
