Viewing another car today for the missus , Audi a3 tdi and the car drive fine and felt ok being g hadn’t been used for a while. After a 10 minute drive I pulled into car park and had a good look around. Now after pulling very hard on dipstick with two hands it finally came out and it was nothing I’d seen before.
looked like a milky white colour with lots of moisture and looked like it had been dipped in candle wax. Hard / solid deposits also light colour( around dipstick ) . ? From what I would have expected there was no oil in it just some really weird stuff ?
what would this be. I just presumed head gasket and took it back from test drive and said no thanks.

 

Yep that’s water and oil mixed and left standing for a while. You were right to pass on that one.
