So you have the plastic intake manifolds that get hot and melt.

What automotive engineer would have ever thought that an engine could get hot enough to melt plastic ?

Just kidding. It's been a good truck except for a few things. That fuel pump was tough to get to.

GM's 3800 series V6 engines have plastic valve covers. They don't get hot, but they do leak

Im not a diehard Ford guy, so I wont defend Ford design decisions. What I can say is that my car has been relatively trouble free. The intake was replaced but it wasnt melted, just warped enough to cause a misfire code. Not the best design but it did last 180k miles. The car is 2008 and now has a shade over 250k miles. It still runs well and is smooth and rattle free.

All the Ford are plastic also. I have changed a lot of ford intakes because the plastic gets brittle and breaks.
