So I just bought an e36 328i coupe I am trying to put back on the road. First most noticeable thing under the bonnet was the duck tape'd up hose connecting a very oily oil catch can.
I want to clean that catch can and empty it of all it's oil as it's very full. I was going to clean out the inside with some hot water first and then just let it dry. Is that alright? I imagine when the engine bay get's hot any left over water inside the can might evaporate and I'm just wondering if this could cause any danger the engine.
