Hi my trucks stock and has 10,000 miles on it . Is it normal to have a visable amount of blow by ? ( by Blow By i mean , with enigne running at full temp, i remove the oil fill cap and smoke is coming out .
blow by I see is alot more common on the 7.3L powerstrokes - most all do it to a degree. Never really noticed it on any of the 5.9L cummins like the fords. Anything is possible. What are you using for oil?
