WAS TOLD INTAKE MANIFOLD GASKET FAILED. OVER A THOUSAND DOLLAR FIX WITH RELIGIOUS OIL CHANGES AND COOLANT FLUSHES, SHOULD NOT HAVE HAPPENED. I HAVE TALKED WITH MANY MONTANA OWNERS OF DIFFERENT YEARS AND ALL HAVE HAD THE SAME PROBLEM. THIS CANNOT BE A SURPRISE! THERE IS SOMETHING WRONG HERE... EVEN TWO DIFFERENT REPAIR SHOPS SAID THIS IS A "COMMON" ISSUE OF THE PONTIAC MONTANA. I WAS TOLD THEY WERE SURPRISED IT DIDN'T HAPPEN SOONER AND THERE WERE SIGNS IT WAS IN THE MAKING FOR AWHILE. PLEASE LOOK INTO THIS! ITS NOT A CHEAP FIX! *TR

INTAKE MANIFOLD GASKET IS FAILING...AND GM KNOWS OF THIS WIDESPREAD PROBLEM AND REFUSES TO FIX IT OUT OF WARRANTY. MY COOLANT WAS LEAKING OUT AND THEY WOULD NEVER FIND THE PROBLEM UNDER WARRANTY, AND NOW THEY REFUSE WITH 4 MONTHS OUT OF THE WARRANTY. AMAZING.*AK
