Default Re: 2004 4.0 V6 having multiple issues help

A couple more quick checks:
a. Sometimes a head gasket issue will manifest by air pressure build up in the coolant system so take the radiator cap off and feel for air pressure. If there is a consistent air pressure coming out you may have a blown head gasket.
b. Check the oil on the dipstick and see if it looks milky or a light color of brown. If so same thing as above, a cylinder/ head issue may be allowing coolant into the oil system.
