4.7 Milkshake

[Logan Klein]

I check the oil in my engine very religiously, since it does have a small seepage coming out of the front bottom side of the engine, between the crank pulley and the oil pan. I checked my oil recently and saw the smallest bit of the feared "Milkshake oil". There was just a tiny tiny amount of the milkshake on the oil cap and fill tube, but when I changed the oil the old stuff looked perfectly fine. Thoughts?

Could be condensation if you are in a cold climate and are doing “short runs”. My hemi always had a little in the winter because it was only a 7 mile drive to work when I lived in the north east.

Oil analysis would tell you if you have coolant mixing with the oil if you want to be 100% sure.

4.7 is a sludge pumper in colder weather when you don't get it hot. Oil analysis would be good to ensure no head gasket issues.

Also listen for start-up knock as you close in on 140K, that goes away as engine warms. The 4.7 has a history of failed oil pumps at roughly that age.

My truck has almost 240k on the clock. No knocking, no valvetrain ticking. Where I live it does get fairly cold though, during the coldest month the temperature will dip below zero on occasion. I have thought about the sludge in my engine, there's definitely a good amount for a 23x,*** mile motor. Any suggestions on a product I could use to clean the sludge out?

The only problem is if you “loosen” something up and it runs through the oil pump and bearings!
