Wife has a 1997 Taurus LX w/ the Duratec 6.  I own a 2002 Explorer w the IRS.  Never owned a Chevy (would before a DCX, now), DCX product or anything that uses minute rice (never will).  I've NEVER had an engine problem.
ONLY mechanical problem I had was a locked up slave cylinder in my F-150.  Take notice, don't be love muffin and puddle-jump when it is -10 below out 

.  Had to push the diddlyer myself.  
They might be from formula 1, but a part that old, toejam, it wouldn't be worth it.
