What does blue smoke coming from the tailpipe of a 1999 Dodge Intrepid mean?

it could be your oil stem seal rubbers in your cylinder head, or it could be your oil rings/piston rings. your timing chain is about to go. These engines have a sludge build up that clogs the oil holes and eventually oil pressure drops in the combustion chamber which causes the timing chain tensioner to loose tension and thereby causing your timing chain to either go slack or snap. Either of these two malfunctions on the part of your main timing chain will cause your piston heads to kiss your valves. You don't want that to happen. have your engine flushed immediately and use synthetic oil from now on. The blue smoke is a tell tale sign that you need to do this flushing now or you will pay. Hope this helps. Blue smoke means you are Burning engine oil. Either the valve seals in the heads are bad or you have bad piston rings. Or you have a blown head gasket which the 2.7L is known for doing.anyway here are the smoke signals 1:Blue equals oil,2:Black is to much gas,and 3:White smoke, this is my favorite is anti freeze shut it down quickly or the engine will be toast...
