Thanks for the replies guys. I did check both the coolant tank and there is no oil floating, no bubbles bubbling which would suggest a blown gasket. I also checked the oil in the car and there aren't any signs of frothing. So far so good. Again, she starts up on the first crank, although I didn't push it today and decided to just have it flatbedded to my indy volvo mech.

When I did start it and let it run for a bit while I checked everything indicated above, there was no smoke, but definitely stinky rotten egg smell - surprisingly strong. So I am thinking the catal. converter and I'll be visiting that station in the morning to put them on notice. I'll let the Board know what happens and what my mechanic tells me.
