Just a guess.  My hoses were clean at 55k when I checked them.  I use
synthetic oil, and use zero oil between changes.  If you use a little oil
between changes, some of the oil you burn would get into the hoses, adding
to the clogging problem many people report.

Seems on some Explorers, the stuff in the hose burns, and melts the hose.

Anybody else whos psyhic?
