Trucks been sitting, oil change produced white creamy oil. Coolant was filled before oil refilled. Drained right into the engine oil pan immediately. Never overheated. Never white smoke. Only rough idle.
Do you
have the same problem?

I suspect we have a warped head or head gasket that has failed. Take a look at these guides that cover this information. I would suggest we start with a compression check to find out if we have a sound engine or what cylinders are suspect. Let me know if you have questions. Thanks

I would like to add that the truck has been sitting, and not running. When I put the coolant in the reservoir it immediately went through and out the oil pan. Immediately, like no resistance with the truck off and not even warm. Would this indicate a head gasket? Or cracked block? Could it possibly be a leaky gasket at the water pump? Up until I parked it a year ago. It was running without overheating or white smoke. It hasn't even been started in over a year. For it to go directly to the engine literally as I poured the coolant in.

Yeah. This would indicate a connection between the head and block that is not supposed to be there. This is most likely a head gasket that is allowing a coolant passage access to the cylinder and the coolant is just pouring past the rings and piston into the oil pan.

I would run a compression check and I am sure you will find the issue.
