I`ve begun the process of winterization and have a problem. I have a `08 5.7 Gxi-j VP. I have attempted to draw my engine oil out of my pan after warming, but am only getting a couple quarts before I start pulling air and it just sputters. I have used two types of pumps a vacuum and a mechanical . Both do the same thing. I also used two methods, sticking the tube down the tube method and have used the screw on adapter method, same results. When inserting the tube I make sure that it bottoms out. I believe the pan was full as my dipstick has always read a slightly high reading. I had the boat at level.
Is there something that I am missing. I believe both pumps are working correctly as they pulled the first couple quarts easily.Is there a trick that would help? Could my dipstick reading be off? I bought the boat used from a dealer so I really don't know the engines history.I ran fine all season without alarms and produced the power and speed expected. I cant get to the pan bottom without pulling the engine, just too tight. Any suggestions what to try to get the last few quarts out.
