just had a 4.7 dakota come in for an oil change... mech drained it and went to put oil in and the valve cover filled up and wouldnt even drain into the motor because of all the sludge

then a few months ago a year old durango comes in with 25k on it with engine noise and still had the original filter and never been serviced once since bought new..... saw it when toredown and you couldnt even recognize half the parts they were so covered in hard sludge.... i just dont understand it
