VALLEY PLATE LEAK DUE TO THE FACT THAT TOYOTA/LEXUS UTILIZED THE IMPROPER SEALANT AND USED THE IMPROPER AMOUNT, LEADING TO THE HEAT EXCHANGER LEAKING COOLANT ONCE THE ORIGINAL, INADEQUATE SEALANT BEGINS TO DISENTEGRATE. THIS COULD CAUSE A CONDITION WHERE THE ENGINE COULD FAIL AND SOMEONE COULD GET HURT. FURTHERMORE, ALL ISFS WILL EVENTUALLY HAVE A CRACKED RH MANIFOLD ON THE #8 RUNNER. THIS CAN CAUSE A FIRE HAZARD IN ADDITION TO CARBON MONOXIDE POISONING.
