View Full Version : Flushing engine oil

" I have a Chris Craft "K" engine that has been to the bottom and back. Have changed the oil several times but it still gets milky when run ( it runs fine by the way). Is there a solvent, like varsol, that can be run through the engine to flush out the contaminated oil? "

" There are engine flushes available in quart cans at most automotive stores, but your situation sounds like you have a water leak into the oil system. Most likely culprit is the exhaust manifold, or if the engine went down hot, it may have warped the head. You may have a lot of crud in the sump holding on to the moisture, but if the oil still gets milky after several changes during several hours of running, you probably have a water leak. "
