I was replacing a heater hose this afternoon in my driveway when i encountered something ive never seen before. When i started the truck up to check for any other coolant leaks i noticed a big puddle of oil gathering under the oil pan, like i had changed the oil and forgot to put the plug back in. By the time i got out of the engine bay and shut the truck off id say about a gallon had spilled from the truck. The leak stops completely when the engine is off and given the rate at which it was flowing im assuming its coming from a pressurized source. It looks like its coming from behind the intake manifold but i wanted to get an idea of possible causes before i start tearing into it again looking for leaks. I thought it might be the rear seal but wasn't sure if itd stop with the engine shut off. Plus the oil starts above where the rear seal is located. Its not a head gasket or anything and there isnt any coolant in the oil or vice versa. So if anyone has some insight into what i might be facing id greatly appreciate it.
