View Full Version : oil in intake hose after winter

04-27-2010, 11:54 AM
Does anyone have any experience with oil in the intake hose? After opening the raw water sea strainer I found it full of oil. My winterizing was to run the engine on the hard filling the intake hose with a premix of anti-freeze untill it came out the exhaust approximately 1.5 gallons. I'm worried that the oil cooler may not have had enough protection from freezing. Any suggestions would be appreciated.

Which engine?
1,5 Gal seems a lot for the raw water system.
Was the engine running when filling, or did you perhaps even fill up the exhaust system?
