I am very familiar with the beautiful songs our cars sing after switching off the engine. The pings and tinny creaks as the metals adjust and return to normal is very normal and interesting to hear but my 986 starts that singing as soon as the car is started. Initially I was worried it was a rotatory engine sound but I realized that even if I switch of the engine the sounds are there and continue for a while

Is there something I should worry about with these sounds or is it the metals just adjusting from the get go
