91 camry wagon HELP NEEDED
 

i recently purchased a 91 camry station wagon with 69000kms on it as my day to day car
now this car until i purchased it had barly moved

driving it home tonight i was going over sydney harbour bridge and the car started ticking and loosing power and loosing power
until we could pull over at milsons point by this time the engine had died

when i popped the bonnet there was oil everywhere.... at first i thought a had blown a hole in the side of the block..... i have been unable to find such a whole so im trying to find where the oil could come from???

does anyone know if there a oil hose on the outside of the block or what could have happened
