Just finished replacing the head gasket and main wiring harness on my 1980 245DL (thanks to the advice on the Brickboard for helping me complete the job)...As I went to refill the cooling system before firing it up for the first time in 3 months (long story...), just as I had the system topped up, I heard "drip, drip, drip" onto the paper under the engine. The coolant is coming from the rear of the engine - the exhaust side is dry, the intake side looks dry (at least down to the head gasket), the heater hoses are dry at the firewall. I only replaced the upper heater hose (the bottom one wouldn't budge). The temp sensor and sender fittings on the head are dry too...So I figure the causes could be:

1) I screwed up the head gasket during assembly (quite likely)
2) The metal tube to the lower heater hose is cracked
3) Coolant is leaking from somewhere that I don't know about...

Am I missing something, are there other possibilities?

Stay tuned, there might be a 1980 245DL with lots of brand new parts for sale...The thought of redoing the head gasket makes me want to drive the car into a wall.
