Hey guys, I fully serviced my truck myself, everything. I drove it in a parade about a month ago , 50 -60 miles total. parked it, I repainted the truck and all , I cranked t today to take it out of the garage and let it idle about 15-20 min. I shut it off to change my air filter, opened the can and I see a puddle of engine oil in the housing. I left the filter in place and cranked it again and it drips oil as the engines running from the housing. What would cause that? It has correct oil levels , and oil pressure ,etc. Its a horizontal filter housing.
Engine is a CUMMINS 6CTA 8.3 6CYL .
Thanks for any help guys.
