I had coolant/oil leak while car was under warranty. At 100,000 miles it developed a major external oil leak.
Repair is a new head and timing chain cover gasket. While the parts are not too expensive ($75.00) the time to remove and replace the head is about 14+ hrs. You will need special tools for some operations. If you are not a mechanic, don't even try it. This is common problem with the 6 cyl engine and oil leaks occour at the right side of the timing chain cover and the head gasket.

Just bought a beautiful 1994 E320 for $3000 for my gf who just finished cancer treatment. Found oil in the coolant res. Mechanic offered to buy it for $500 bucks when it finally dies. Doesn't overheat, doesn't blow white smoke. How can I extend the life of this thing? I really blew it by buying from a curbside charlatan, who had no interest at all in trying to make the deal more equitable. Damn it.
Interfluid mix, car overheating, oil leaked. Head gasket was replaced.
