Okay, this is definitely a problem with the coolant mixing the engine oil. It is probably being introduced into the combustion chamber through the intake manifold gasket and then pushing some of it past the piston rings and into the engine oil that way. There is a possibility though, that your intake manifold might be compromised by a crack or something of that nature, causing this condition. I would redo the intake manifold gaskets and reinstall the intake manifold. If there is still a problem then I have included a guide on testing the intake manifold in your vehicle in the diagrams down below. Please get back to us with what you are able to find out.
