1993 TOYOTA COROLLA Engine And Engine Cooling Problems

EXHAUST MANIFOLD HAD A LATENT DEFECT IN THE FORM OF A CRACKED EXHAUST MANIFOLD. AS TIME PROCEEDED, THE CRACK BECAME AN ENTIRE SEPARATION OF THE MANIFOLD NEAR THE CENTER. THIS SITUATION ALLOWS POISONOUS EXHAUST GASES TO ESCAPE WHENEVER THE ENGINE IS OPERATING. THESE GASES ARE PRIMARILY CARBON MONOXIDE -- AN UNSCENTED AND DEADLY GAS -- ALONG WITH OTHERS LESS HAZARDOUS. SINCE THIS IS AN INHERENT DEFECT, EITHER IN THE DESIGN OF THE MANIFOLD OR IN THE QUALITY OF THE MANIFOLD (OR BOTH), I DEFINITELY BELIEVE THE MANUFACTURER SHOULD RECALL THE 1993 TOYOTA COROLLA VEHICLES WITH 1.6 LITER ENGINES AND REPAIR OR REPLACE THE DEFECTIVE PART. *JB

I HAVE REPLACED THE EXHAUST MANIFOLD THREE TIME,THE MATERIAL USE TO MANUFACTURE THIS PART WAS CHEAP CAUSING IT TO CRACK. *NM

FOURTH CYLINDER WAS DAMAGED BY A LOOSE VALVE, REQUIRING REPLACEMENT OF ENGINE. DAMAGE MANIFESTED AS I WAS MAKING A RIGHT TURN AND REACCELERATING. CAR BEGAN TO SLOW DOWN, STEERING WHEEL BECAME RIGID, A CLOUD OF SMOKE CAME OUT, AND THE CAR JUST DIED.*AK

DEALER TOLD ME THAT EXHAUST MANIOLD CRACK WAS VERY COMMON WITH 1993 TOYOTA COROLLA. EXHAUST MANIFOLD CRACK CAUSES INPROPER AIR MIXTURE AND EXCESSIVE AIR POLUTION. CASUES IMPROPER AIR/FUEL RATIO IN CATALYTIC CONVERTER, AND DANGEROUS EXHAUST FUMES IN CAR'S PASSANGER COMPARTMENT.

ENGINE ROD "BLEW-UP" THROUGH ENGINE BLOCK ACCORDING TO DEALER. THANK YOU AND HAVE A BETTER DAY.

DESIGN OF EXHAUST MANIFOLD CAUSED IT TO CRACK, DUE TO LACK OF VENTS.

EXCESSIVE EXHAUST FUMES ENTER INTO VEHICLE, UNABLE TO RECTIFY PROBLEM.

OIL PRESSURE SWITCH IS IN A BAD LOCATION, THE LOCATION ALLOWS THE ALTERNATOR TO HIT THE SWITCH WHEN GOING OVER POT HOLES, CAUSING FAILURE OF THE SWITCH.

THE EXHAUST MANIFOLD HAS CRACKED, CAUSING HEADACHES AND ALSO THERE IS A NOISE IN THE FRONT OF THE VEHICLE BEFORE THE CAR HAS WARMED UP. PLEASE DESCRIBE DETAILS. *AK

HARMFULL LEVEL OF CARBON MONOXIDE FOUND INSIDE THE PASSENGER COMPARTMENT OF THE VEHICLE CAUSING PERMANENT INJURY TO DRIVER.

EXHAUST LEAK CAUSES HEALTH PROBLEMS.

EXHAUST FUMES INSIDE VEHICLE. *AW
