top end of dipstick ,but only after a long run,don't notice when just normal around town driving,but after a 300 hundres mile interstate run,notice it only on the dipstick,near the top(handle end),bottom of valve cover plug,and pvc valve has no residue??any suggestions???coolant level does drop some periodically,??but did that long b4 the milky look on the dipstick started??any suggestions??

 

You already know the answer. Water in the oil.

 

question is where's the source???it doesn't overheat and the pppplugs look good?appears more like condensation?

 

on a 300 mile interstate run, I would think that the oil would get hot enough to burn off any condensation. If its not burning coolant, then I dunno. If you had said you weren't driving it far enough to get the motor to operating temp, then I would say condensation could be the answer, but I don't see that w/ the engine at operating temp that long.

 

sense,this is second road trip that i've noticed this,

 

A functioning PCV system usually controls that moisture very well. Make sure your's is operating.

 

If it were just mere condensation, you would find a yellow film on the underside of your oil cap. This might be a very small head gasket leak. Also check your coolant for "rainbow swirells" meaning oil in your coolant. Any white smoke other than the normal steam? Also look for crappier idle and such. If all this exists, you will need a head gasket job. Its not that hard :P
