I noticed that my 98 Caravan was dripping oil. Only 3-4 drops after I shut off the engine. When the engine iddle and is warm enought, there is some light smoke coming from the front of the engine, probably caused by the oil leak.

My question: Where can be that leak from? Cover valves gasket or head gasket?? Or maybe somewhere else??

Thanks,
Bill

 

Might be the oil sending unit.

 

where is the oil sending unit located on these vans?

 

try tightening the valve cover bolts that might they tend tend come loose see if that helps

 

Smoke? Sounds like the oil is getting on the exhaust manifold, in which case the leak has to be above that location. One such location would be the valve cover gaskets.
Are you sure the leakage is oil and not transmission fluid (red in color)?
