1986 MITSUBISHI MIGHTY MAX HAD A RECALL FOR THE EXHAUST MANIFOLDS. DURING THE APPARENT PART RECALL CLAIM, IT WAS SPECIFIED THAT THE EXHAUST MANIFOLD PART WAS TO BE REPLACED BECAUSE OF DANGER OF FIRE AND OR EXHAUST FUMES ENTERING PASSENGER COMPARTMENT.

THE RECALL SEEMS TO BE NO LONGER POSTED ON THE RECALL LISTING, YET I HAVE THE ORIGINAL RECALL STICKER FOR THIS DEFECT STILL POSTED ON MY VEHICLE. AN OBVIOUS COVER-UP TO BUY TIME PERHAPS BY REPLACING A DEFECT WITH THE SAME POTENTIALLY LIFE THREATENING DEFECT.

THE PART IS AVAILABLE FOR INSPECTION AND HAS A VISUAL CRACK WRAPPING AROUND THE #1 AND #2 EXHAUST TUBES WITH A 1/
