loosing engine oil... on 2004 Chevrolet Express 2500

Gradually I have been loosing oil...I replaced the oil I lost...Its really cold here in Oklahoma.I started the van the other morning an it had a purring noise/vibration sound. It vibrated till it warmed up and it stopped. Got in it today. Same vibration. Drove it about 10 miles. Stopped and had oil going everywhere. No Watt in oil.No high temps.But I have had issues with oil pressure low. When oil started shooting out president was pegging 40. It hasn't pegged 40 in a while. All help is greatly appreciateed. This is my work van. No van no work...Thanks

No way to tell from here where the oil is coming out of you 2004 Chevrolet Express. If the oil is leaking a bad as you say, it should not be to difficult to see where it is coming from. Make sure the crank case if full of oil, and run the engine at idle and see if you can tell where it is coming from. You may need to clean off some of the oil and recheck.

Oil caked around filter...Thinking the filter isn't being changed when oil is.Changed oil and filter myself. BLACK & THICK..I can't find it leaking any where now. Do u think filter gotplugged and went past seal.

Your leak could have been at the filter. Please keep an eye on things to make sure there are no other leaks.
