2004 Mercedes Benz E55 AMG – Valve Stem Seals Blown Out, Spectacular Smoke Show Guaranteed
This car is a beautiful, luxurious beast. Its owner loves to drive it fast. The valve stem seals were a good 1 to 2 mm off the stems, producing an incredible quantity of smoke out of the tail pipes.
The balance shaft sprocket “guide wheel” has begun to eat itself – compare old with new.
Also, lots of external oil leaks.
Now, clean as a whistle. Off to the quarter mile.
