I need to replace 2 POC's and the valve cover gasket on my 01 V8 LS. The dealer quote was too high and I am wondering if there are any mechanically savvy people like myself who can tell me the complexity of this job for a do-it-yourselfer. I was a mechanic in the military and am somewhat mechanically inclined, but never got into Lincoln's. If anyone has done this themselves and knows the process and special tools (if any) involved please help. Thanks.
