smoke???
 

this may be a stupid question but here goes anyway after drivin my cherokee if i pop the hood and open the oil filler cap on the valve cover it smokes quite a bit what would cause that??? is it bad for the jeep ???
its a 89 auto 4x4 4.o thanks in advance

This is perfectly normal when hot oil meets with cold air. It is oil that is vaporizing. No big deal at all, Bro. :thumbsup:

good peace of mind thank u
