Verified

The 3.7L V6 and 4.7L V8 in very cold climates (below freezing temperatures) moisture can collect in the Positive Crankcase Ventilation (PCV) system and freeze. This will cause various drivability problems and there are revised PCV system components to repair this concern.

    I have lots of yellow pudding in my 4.7 L dodge ram oil cap and some foaming on the dip stick...
    Only stalls on really cold mornings ( below 0'C Degrees ) at stop lights and surging idle freqently... I was worried about a head gasket being blown untill seeing this...will replace pcv next...i've been adding seafoam to crankcase since i noticed this problem.. plus i cleaned throttle body,iac, replaced tps so far..planning to check for vacuum leaks if pcv doesnt fix it..

    Looked like mayonaise inside oil filler cap. Was afraid it drain into motor oil!! Changed pcv valve poured 5oz. Seafoam down pcv tube to clean. Poured 6oz. seafoam in motor oil. Drove the truck to work change oil and filter. Will definetly watch this a lot closer!! Poor design for sure. Dodge has been around long enough to know better. I geuss?
