I am having oil coming out of the overflow on the motor. I read someone said they had the same problem and it was an injector and the problem happened while they were driving. My problem happens after I park it for a few days after working all week. It is a 2500 2004.

 

Is the oil level overfilled? It's normal to have some oil come out the overflow and leave a splotch or 2. If the oil level is not changing, have an oil analysis done to see how much fuel is in the oil.

 

This happened about two weeks ago. So I changed the oil and filter and ran it for 1000 miles checking oil every other day. It was ok for first 500 miles then got bad. Who does oil analysis.

 

Blackstone for the oil analysis. What do you mean by got bad? If you have an increase of oil you may have a cracked injector body, loose cross over tube, or a seal leaking on the CP3 injection pump.

 

Yeah how bad is Bad??

If you have fuel in the oil please do NOT drive it any more!!

 

Small puddle under truck setting all weekend. Not while driving it is fine. I guess I need to take it to a shop.

 

Start the engine and turn your oil fill cap upside down on the fill hole....if it blows off then you're losing compression from the rings which will cause you to have oil come back up through the top end and out the vent tube. Just a thought.
