I am working on an older boat that sat out in the weather for years. It had a ton of water in the motor when I did the first oil change. Now that it's running, I think that its picked up more water that was in the oil cooler or other areas of the motor that does not drain out. I noticed a little bit of water in the valve covers after I first got it started, but didn't think much of it. I cleaned it out and moved on.
I only ran it for a few minutes the first time and it was running rough and backfiring through carb. (I now suspect water is partly to blame.) I ran it a little more last night and I could hear the water boiling in the valve covers. So, it looks like I have more water in there than I thought. Water is slowly coming out of blow by. Steam/drip.
So what to do at this point? Should I keep running it so that it boils all the water out? Or should I not run it at all and keep changing oil? I really want to clean the filter and change the oil to get rid of water and certain gunk that's in there now, but I am guessing it will just quickly get water in it again. I have seen all the posts about suggested oil and I plan to keep using Aeroshell. That said, I don't want to dump $80 in oil in there just to have to change it again after 30 minutes of trailer running. Any suggestions on any "sacrificial" cheap oil that I can use with no harm? Perhaps some cheap walmart oil and I could actually get 2-3 oil changes before I go back to aeroshell. (I would only be running it on trailer.)
