Hello I parked more than a month
Now when I drive it I hear like the timing chain is loose
But that sound shows up when I drive !! Not when the car is in neutral, when in neutral and make sudden rpm increase I hear same like loose chain sound but from the torque converter area !! Ideas ??

Later I will take it to the mechanic and hang the rear end so I can put in drive and hear what exactly that sound is . However I want to know if someone had similar issue with our legendary reliable cars
