I bought this 2015 charger SE (133k miles) 8 months ago and have done regular and proper oil changes since. Took valve covers off for routine maintenance to discover this sludge fest (Pics 1-3).
I did 2 full Seafoam flushes with new oil running half a can into my crankcase idling for 20 minutes each. First flush came out pitch black. Second came out relatively clean. I don't want sludge buildup clogging valves so after the second I took the oil pan off to clean everything. After 2 Seafoam flushes (Pic 4), this is how clean my bottom of engine was. Oil pan was flawless. Darn near no metal, nothing abnormal for a car with 133k. Maybe 2-3 small "crumbs".
I then threw in 5qt valvo restore 1 qt MMO. Running that for about 200 miles and then checking valve covers.
What's the prediction with everyone on how dirty or clean the top will be still?
