Re: 380SL timing tensioner permanent fix?
Timing chain is a 100,000 mile fix. The single row can fail quickly. THe double row chain should run for 120,000 miles without any service. Change the oil often. The timing chain should not rattle long at start up. Maybe for 10 seconds. The way it works is that thte hydraulic chain tensioner fills with oil when the oil pump pressurizes it. Perhaps you have a problem with the oil supply to the tensioner. Normally the guides get brittle (Overheating is very bad) and when they break they get driven between the chain and sprocket. New guides, tensioner and oil tubes should also be replaced. Broken guides are more likely than the chain jumping. This should not have happened after the double row chain was installed. If there were new guides and tensioner it should run a long time. Perhaps somebody overlooked something during the rebuild?<br>Steve, 107 driver
