1991 TOYOTA PREVIA Engine And Engine Coolingengine Problems

I HAVE A 1991 TOYOTA PREVIA LE. THE DISTRIBUTOR O-RING AND VALVE COVER GASKETS WERE LEAKING OIL, AND THEY LEAK RIGHT ONTO THE HOT EXHAUST MANIFOLD. I REPAIRED THESE PROBLEMS, AND ALL IS WELL, HOWEVER, I HAVE SINCE SEEN MANY INSTANCES IN VARIOUS FORUMS ONLINE WHERE THIS HAS HAPPENED TO OTHERS, AND HAS RESULTED IN A MAJOR VEHICLE FIRE. I BELIEVE THE WORD NEEDS TO BE SPREAD TO OTHER OWNERS OF THIS VEHICLE TO CHECK FOR THIS PROBLEM BEFORE IT IS TOO LATE. IT IS A SERIOUS PROBLEM, CAUSED BY THE DRYING OUT AND CRACKING OF RUBBER SEALS. I DID, IN FACT, HAVE FLAMES WHEN I NOTICED IT, BUT I WAS ABLE TO EXTINGUISH THE FIRE BEFORE ANY DAMAGE WAS DONE. PLEASE SPREAD THE WORD. *TR

ON A RETURN TRIP FROM CA. MY TOYOTA PREVIA JUST STOPPED RUNNING. IT WOULD NOT START AGAIN SO HAD TO HAVE IT TOWED TO LAS VEGAS NV. ABOUT 50 MILES. IN TAKING THE VAN TO MY MECHANIC HE SAID THAT IT WAS TOTALLY OUT OF WATER AND ALMOST OUT OF OIL .THE FIRST PISTON HAS NO COMPRESION THE REST ARE BELOW 100 PUONDS. THE VAN GAVE NO WARNING THAT IT WAS OUT OF WATER OR EVEN LOW ON OIL, ALSO THIS VAN HAS EXTRA OIL UP UNDER THE HOOD, AND IT HAS A PUMP THAT SHOULD HAVE PUMPED OIL INTO THE ENGINE, IT DID NOT IT FAILED. ALSO THE WRANING GAUGE DID NOT INDICATE THAT THE ENGINE WAS OVERHEATING. THANK YOU FOR YOUR TIME RICH IN VEGAS. *AK
