possible blown head gasket??? Options

[ian0490]

I got a 94 gt with about 160k on it. Started over getting on me. Looked into the thermostat and it tested fine. No leakage on the floor on the passenger side and no sweet smell in the vents, so probably not the heater core. Before i go into the water pump or the head gasket, i want to check if I'm right. When i emptied out the radiator, the water in it is oily brown looking. Im assuming the oil is mixing in with the water. I haven't dumped out the oil in the pan yet but when i looked at the oil cap it had slimy white gunk on the inside. I'd it safe to say it's the head gasket or am i over looking something?? I'll include pics similar to what it looks like.

Possible cracked head too. Do a block test and it will give you answers. Coolant turns oily brown when its old, but white buildup on a dipstick CAN be a head gasket. Also could be moisture in the crankcase. There needs to be a decent amount to consider head gasket.

Do you have a pic of the dipstick?
