Yep, sounds like a blown head gasket. If there is a failure between the oil
and coolant ports the oil will enter the collant since the coolant is at a
max psi of 15 by the rad cap and the oil can be any where from 25 to 75 psi
depending on the oil type and health of your engine. Water can enter the oil
through the same failure when you turn off the engine because the coolant
presure remains while the oil pressure disappears. If you get a failure
between the cylinder and coolant port the coolant will get presurized and
can also be forced into the oil (but that is usually accompanied by white
smoke at the tail pipe from coolant drawn into the cylinder during the
intake stroke. Basically, once there is a failure in the head gasket you can
get any combination of contamination symptoms.

On the way home today i suffered a total loss of oil pressure
when i got home i checked the oil level and found none in the engine after
topping it up started it up and had pressure for a few seconds then lost
all oil again.I then noticed the coolant system was pressurized upon
checking it found the coolant full of oil. Has this happened to anyone else
usually when a head gasket went before the coolant ended in the oil .
thanks
