Hello, i have a 2005 explorer 4.0 liter sohc with 190k miles on it. About 5 months and 2k miles i started to hear a rattle that starts about 10 seconds after i start the engine. Sometimes the rattle goes away when the engine is hot sometimes it doesn't. Now i found out that it is due to a bad timing chain tensioner. I already ordered a new Motorcraft tensioner. My question is if the probability is high that the new tensioner will kill the timing chain and if i should leave the old tensioner in. I would highly prefer to change it but i am not sure about it. I don't know if and how much the cassettes are damaged but there is no rattle for the first few seconds after a start up.
