What is the loud tic-toc noise after I start a car and after I turn off the car for a few seconds and goes away?

It could be the lifters. Depending on the mileage and care as far as frequent oil changes one o rmor eof your lifters may be making a tickign sound. As the oil pressure builds up..........say after a minute or two does it go away? Try this....just turn the engien on and let it on and see if the ticking goes away when it warms up. If not, then it is probably not the lifters. The lifters are hydraulic and they maintain a certain oil pressure and as they get old they gum up from infrequent oil changes and they lose some of their ability to hold the pressure so they tick.
