Blown head gasket or oil cooler

[power=dsm]

well not to long ago, i got in a little accident and drove my car for 5min with little or no coolant. The temp never even went close to the hot it went about 3/4to the top.
Well today i noticed that my radiator light came on so i checked my reservoir and it was empty. Then i saw coolant on the head which is leaking from my valve cover along with oil. So i checked my oil and there was coolant inside.

Now my question is how long can i drive like this before getting it changed? What can happen it i don't get it changed soon(well it hurt the turbo because it's oil cooled? the weird thing is the car isn't smoking at all, which is why i think it's not the head gasket??? no white smoke !!this is on a rebuilt motor with less than 13000km on it

i'm missing some oil aswell, can this be casued by the headgasket or the leaky valve cover

your headgasket can still leak without being totally blown, or blown into the cylinders.

so the only way i'm gonna know is if i pressurize the cooling system

could the headgasket be blown but its not blowing steam because that part of it is still intact?

ok so i just checked my compression and it turned out all the number are 150's which is lower then the last time i checked 160's
now my car started to smoke white at idle and there was condensation on the floor near my muffler. But why is the compression ok if my head gasket is gone??

how do i check my oil cooler to see if it's causing the problem??

k well i emptied my oil today and there is little to none, water in the oilt probably just from condensation.
So i started my car after changing the oil and to was good for a bit then it started to smoke white again, and i noticed that there is coolant coming out from the muffler? so i have to think that’s it's coming from the turbo and it just being shot out the muffler?
