cause i think my head gasket is blown but i have been still driving on it...and the leak has gotten exponentially worse....the car has no signs of overheating as the temps are the same....and because unlike most cars it's leaking oil instead of water.....

what are the potential dangers of driving on this for too long...will the head warp?....cause i'm debating if i replace the head gasket, if i will need a new head(1500 +1000head) or buying a much lower mileage used engine($2500)....

i know how this goes on other cars....but then again it is not the ordeal it is on a benz....my head job could cause as much as another car...lol....and it usually doens't take ten labor hours to complete....so any help would be appreciated....
