Coolant leaking on back side of motor
I have a 2004 F350 6.0litre, I get a pool of coolant under the truck when it sits for awhile without being started. It doesn't seem to leak while it is running.I crawled underneath and it seems to be coming from the drivers side,up on the very top corner of the head, it then runs down the motor,onto the bell housing and then drips on the ground.Truck runs fine and dont notice a difference in the coolant reservoir,about 3/4" below the min. mark. I did notice however a chalky white substance around the reservoir cap on the reservoir, where it came from i have no idea.
Any thoughts would be helpful and appreciated!!
