Hey guys got another question! I have had my 03 lb7 duramax for a little while now and it has leaked a tiny bit of oil daily since i bought it. I finally took a good look at it and i found that the oil is coming from a single pipe. The pipe comes from both my valve covers from and "t's" off into a single pipe that shoots straight to the ground with no where to go? Seems to be a pcv breather pipe or a blowby pipe of some sort? What do you guys figure? Im not very familiar with diesels yet. It only leaks about 10 drops of oil if it sits for half a day? Thanks for any input!

Your describing a PCV reroute, it's normal to have some accumulation of oil dripping from it. Mine rarely drips but has an accumulation of wet oil at the end of the tube. The dripping at rest is just blow buy slowly dripping down the tube. Some trucks have more blow by than others, some that have a lot are fine but some have alot and have a motor bout to fail. If it's not eating oil or blowing out the hose with pressure and hazing while running I'd say your good.
