2004 f150 white sludge under oil cap a problem?
I drive a 04 f150 5.4 3 valve and I noticed this since I got the truck that when it gets colder out I get white sludge under the oil cap from condensation. I put a new thermostat in the truck and it runs at 190-195 and my average drive to work is 22 miles each way. I run ams oil synthetic oil and change it every 5k. Is this normal for these trucks?
