jeephack Posted July 10, 2011 Share Posted July 10, 2011 Recently, I have noticed that the amount of fluid in the crankcase has been increasing instead of decreasing and the oil seems to be a lot thinner. Oh! and also, coolant is mysteriously disappearing. Any thoughts? :shake: Link to comment Share on other sites More sharing options...
JeffN Posted July 10, 2011 Share Posted July 10, 2011 most likely is an injector washing out the cylinder walls, smell it and see if it smells like gas. If it is milky colored it is probably antifreeze and you have a blown head gasket/cracked head or cracked block Link to comment Share on other sites More sharing options...
JeepcoMJ Posted July 10, 2011 Share Posted July 10, 2011 head gasket or cracked head. not likely, but could be cracked coolant jacket. either way coolant is getting into your oil. stop driving it. Link to comment Share on other sites More sharing options...

Incommando Posted July 10, 2011 Share Posted July 10, 2011 Not knowing what you are working on, if it is a carb-ed engine with a mechanical fuel pump the fuel pump diaphragm could be leeaking gas into the oil as well. Link to comment Share on other sites More sharing options...
