Thanks for the replies fellas.I have driven the truck over 500 miles and when I put the engine together I primed the oil pump and engine as you described so it's not that.Hey David now what you told me is a strong possibility.I changed the oil a few days ago and I think I recall seeing a hole there and for an instance wondered about it.Also back when I was putting the engine together I also think then I saw a threaded hole inside the oil boss and wondered then what it was.Well to solve this I'm dang sure going to remove the filter tomorrow and look.Thanks alot again for your insight.I will let you fellas know the outcome.Take care all......Sincerely,Gerald
