03 7.3 coolant in oil HELP!!!
I have search and nothing quite matched. While on highway with cruise control on at 70 MPH everything seemed fine when I noticed the CHECK GAUGES lamp on and the temp pegged. As soon as I kicked off the cruise and started for the side of the road the temp when right to normal. With engine running I noticed the reservoir empty while slow loosening the cap water surged into the tank after a few slow tries I got it open with and it was nearly empty. I pulled the oil fill and there was steam. I put in water and watched a bit, no exhaust issues and water held. (nothing leaking anywhere either) I continued due to my location. The truck drove fine nothing wrong, in 30 min checked again and it need about a half a gallon of water and still had steam with oil fill off and no oil in water. Got home and searched everything. and thought with 135K on truck and cruising at 70 the water pump cavitated which affected flow which caused the over temp till RPM change and the a cavitation hole was created in the front cover. SO I took off the water pump to find nothing wrong with the front timing cover (damn). I fear I have a head gasket failure that is NOT related to the cylinder area. UNLESS the wealth of knowledge on this site can tell me something else like a weird fault in oil cooler which I thought would put oil in water (don't have that). I have to assume head gasket or crack somewhere that will require me to flatbed it to a garage. ANY HELP WILL BE MUCH APPRECIATED!!!! Thank you.
