Need help, oil in anti-freeze 80 240d! - PeachParts Mercedes-Benz Forum

I am not happy, just finnished replacing head gasket including flush and refill of Dex-Cool (Yeah the expensive kind!) anti-freeze, ran it around the block and the nice orange color was black! When I did the head gasket I thought that was the only place for water and oil to mix but there has got to be somewhere else, any ideas? Not running very smooth either. Thanks for any assistance in advance!

Two awful thoughts enter my mind: Cracked block. Cracked head.

Is it possible that there could have been just water in your car's cooling system at some point in the past, and that it subsequently froze?

Not sure what else could crack a block. Could washing a hot engine with cold water do it?

Good luck with your 240D...

I have only had the car a little less than 2 weeks. I drove it to work 2 days after I bought it then it started doing this. Possible that it wasn't where it should have been on coolant protection I guess. It does have an oil puddle under it so I'll be checking that out in the morning. Thanks for your thoughts!

Any reason to think that the PO was trying to get rid of a known problem?

Not really, worked fine when I looked it over the first time but had been basically sitting for several months. I continue to hope that it is something that I can fix without replacing the engine. Is the water pump self lubed or does it use oil?

Never saw a water pump on car lubricated by anything other than coolant or sealed bearing. Allow that I have led a sheltered life though. Seems Funny that car is not running well though as leakage is between oil source and coolant. Nothing to do with combustion space. Unless crack or whatever is quite extensive.Also cannot remember any oil/coolant heat exchange device on this model outside of block/ head area. Wonder if you checked head and deck but mostly head for flatness before completing gasket change. When you were flushing /cleaning did you turn heater on to get any trapped oil out of heater system? Or just turn on during drive with new coolant? Own a couple of these and would be pretty disturbing to have happen. People with more experience will probably give much better advice especially about most common failure on these as there are a few 616s around. (hopefully oil pool on ground is from head to block joint area as you might get a break locating the problem) ( if automatic make sure leakage is not between auto transmission cooler and radiator forgot to include this) (one last thing is to go over old gasket you changed for any evidence of failure or poor contact)
