I found the problem....it does have a blown head gasket...... replacing the intake manifold gasket just hastened the demise of the head gasket as it put more pressure in the area that blew..... I was getting a #1 cylinder misfire, so I'm assuming that is the area of the problem..... I do not have the time right now to replace the head gasket, so I used Blue Devil pour in to get her down the road for a while until I can have the time to do the job....probably first of the year.
