oil in the water??

Could go either way. It depends on where the the HG fails.

 

*edit* That's not to say you have a blown HG. The fact that your rad has just been changed is the obvious thing to check out first. Are you 100% certain its oil? Have you got any water in the oil? Mayo on the dipstick or oil filler cap?

no overheading etc, just that the rad got squashed when i hit the car and i got the rad replaced.

 

i understand that the rad also has oil in the bottom of it? is it an oil cooler as well?

 

maybe from before when it got hit...the rad split inside?

If the car is an automatic it will have had a transmission oil cooler in the bottom of it. If this ruptured transmission oil (fluid) will get in the water, but much more worryingly, wat will get in the auto gearbox, which can cause massive damage.

Auto boxes and water are terrible combinations, it causes break down of the facings on the clutch plates and brake bands in no time at all, and corrodes the valve blocks, which are made to tolerances of microns. It emulsifies with the fluid virtually instantly, and although the temps may be high enough to evaporate some off, it just condenses on the cooler parts of the casing, like the tailshaft housing, and re enters the lubricant sump. The vent is tiny, not big enough to allow rising water vapour to escape. Any bigger and the thrashing fluid would also escape.
