Why the holdup?

To answer the question that I am sure all of you blog readers are asking…no we have not moved in to St. Mary’s, GA permanently. Very soon we plan on getting underway again and heading for the Bahamian islands.

Our engine has been continuing to exhibit some strange behavior with very inconsistent oil levels. It would go up for a little while and then it would go back down, and we decided to take a little bit of time to get it completely sorted out before we leave the country. The engine troubleshooting indicated that our oil level would go up while the engine was not running, so we found a good secure anchorage next to our friends on Anthyllide and proceeded to not run the engine. After about a week the oil level had risen very significantly, so it was time to drain the oil and see what was in our oil pan other than oil.

We managed to pull out this liquid

This is water that was sitting in the bottom of our engine oil pan! YIKES! Thankfully we didn’t run the engine with this much water in there, but it indicated that we have been collecting saltwater and then evaporating it out of the oil for a while now.

The good news about having water in the oil is that there are very very few options for how it can get there. The mostly likely cause is our cooling water pump. It bolts on to the front of the engine and has the possibility that if seals fail then it can leak into the timing case on the engine.

We had a problem with this pump dripping previously and a rebuild had appeared to fix the problem, however now it looks like the rebuild just changed the location of the drip to a location where we couldn’t see it. We currently have a disabled engine, but have a brand new raw water pump in the mail. While it is shipping we are going to continue to monitor our engine oil level to make sure that disconnecting this pump actually fixed the problem.

After identifying the fact that we had salt water in our oil we changed the oil and oil filter twice to try and remove any salt from the system. After we reinstall the new pump we will run the engine for about 25 hours ( not continuously) and then change the oil one more time. Hopefully this will end our engine excitement for a long time!

Meanwhile we are enjoying the reasonably warm weather here in St. Mary’s. The town is full of very friendly people who have made us feel very welcome here. We even met another boat registered out of Portsmouth. The owner Ron has sailed his 33ft steel boat around the world in the high latitudes around Cape Horn. He has amazing stories and is giving up cruising (at least temporarily) to bike around the United States. If anyone is looking to join us we can check out his boat for you…I’m sure we could delay another week before we get under way.

One thought on “Why the holdup?

  1. Nasty looking stuff! The other place water can get in is through the exhaust mixing elbow. This can happen if your vented loop is not working properly. In fact, water should not be able to get in anyplace after the engine is off if the siphon break in the vented loop is working. Some installers don’t even put one in…..I have drained a few engines full of water over the years where the vented loop failed or was not installed correctly.
    Good luck and have a safe trip to the Bahamas.
