before getting into my car i noticed a puddle of antifreeze below it. i drove to my friends house, ride was fine, nothing strange happening but when we investigated, i had no oil, pretty much bone dry, however unlike the puddle of anti freeze, i saw no drips of oil anywhere, or any puddles. i had 2 of my hoses replaced, and the leak of antifreeze isn't coming from either one. Most of it dripped all over my block so my friend thinks i might of blowng my head gasket but not 100% sure. After fillin it with 5w 30 castrol gtx oil, we drove around a bit, punched it a few times, no smoke coming from anywhere, and when i got home, i checked the oil level still fine. Any other ideas on what caused the leak or why i had no oil? thanx in advance for anyone who helps me out
