Is there an easy way to fix timing chain rattle on start up without ripping the car apart and messing with timing

Hello, You can try replacing the timing chain tensioner, but that requires pulling off the tmiing chain cover (engine front cover). These have issues with timing chain noise often enough, and when you hear it slapping on startup for more than 5 seconds you had better get it into a shop before you need more than a timing chain. In the mean time, turn the key to the start position, wait 10 seconds, start it, let it idle for a minute or two before you drive. That will save some wear. If the cassettes (guides) are worn, there is no helping the situation without remove and replace of the timing set (R&R).
