Need help with m103 blown head gasket

Hey guys,

My friend has a 1991 300E with 74,000 miles on it and a blown head gasket. We have an appointment with Pierre on the 17th to do the job, but need to be able to drive it there and back.

Pierre informed us that it would be okay to drive, but today my friend ran in to a problem and had to be towed. After a 20 mile drive, the coolant hose that comes off the block and goes to the heater core and windshield washer fluid heater burst.

After getting it home tonight, I flushed the system for him twice. We fired it up and it seemed to do okay, lots of brown crap everywhere which we were expecting. However as it approached 100* the coolant in the expansion tank began to bubble a lot, but did not steam. It was as if there was air escaping. Above 100*, it did it even more and now it was nearly 100% chocolate milk shake colored ooze. We shut it down, and it dropped to 80. I flushed it again, filled with antifreeze, and called it a day.

Now it will stay below 100 while driving, in fact it will be at about 85 on the highway. When the hose burst today I'm assuming it's because he had sat for too long, and it caused a build up of pressure.

My question is if we need to make the trip to Pierre's, a roughly 60 mile drive, would we be okay to do so as long as the temps stayed down?

Also the aux fan does not come on, blower is inop as well.

Thanks, hopefully we wont need a tow to get there =[
