Hey guys. Im having trouble with coolant lose in my VE 3.6ltr. Cant find a trace of a leak anywhere. Have hardly been driving it because of the issue. Have been told its done an inlet manifold gasket but no coolant passes through the inlet manifold. Another mechanic said its blown a head gasket but i heard thats pretty rare for the alloytech. Its using a fair bit of coolant and have to top it up at the cap after i drive it. Have taken inlet manifold off and taken spark plugs out you can see that two on the passenger side are clean like water has gotten in. What do you guys think.
