ok my car has a few problems and on of them is this
the hose that comes off of the top of the radiator is its normal temp while the engine is running
the other big hose that comes off of the bottom of the raditor is cold
i changed the thermostat and it still has this problem
and the next day i looked in the bucket i drained the coolant into and it had separeted and there was oil in it
so now i need a head gasket

but before i do all the work to it
could it be that the block is cracked internally and the collant in the water jacket is mixing with the oil in the oil gallery

my friend who is a mechanic suggested that it might be cracked because if the main hose to the block is cold that means the block is getting really hot
but it could have been really hot and warped the head, and not be cracked


if any one could suggest something i would greatly appreciate it

thanks
Ryan
