I am getting ready for my swap out as well but let me know how yours goes it said in the report you needed to reprogram the cpu. let me know if you have yours reprogramed. I may not change my valve cover if yours works out, but have notice a little oil in the pcv valve hose.
Nothing i have not seen in other cars but again it is a plastic manifold or part plastic.Thats about as bad as plastic radiators.

Anyone else uncomfortable with the PCM reprogram. The reprogram prevents the associated pinging that results from the carbon buildup. So I'm assuming the reprogram retards timing, maybe just in certain situations, that will probably prevent pinging but at the expense of MPG and performance.

Also as far as the new valve cover goes, I think it probably reduces the oil passthrough to some extent but does not prevent it entirely. If it prevented the problem entirely then the 2001 and newer Windstars wouldn't have the same P0171/P0174 issues since they came with the redesigned valve cover, but they do have the problem. Maybe just not as quickly with the new valve cover.

I did replace my valve cover on my 2000 in hopes that it might delay the repair for a while.
