1997 Ford Contour Engine Noise Coming from Top End

This zetek engine makes an awful lot of lifter noise. How do I tell if they are pumping up? If they are working properly is there a shim that can be installed to take up any play? What else could make such a racket and still allow the car to run great?
Thanks,
Vince


Yes, I was out taking pictures of boats that day.[img:ccff2c1139]http://www.2carpros.com/forum/automotive_pictures/581064_Boat_for_Sale_2.jpg[/img:ccff2c1139][img]
