1996 LEXUS ES300 Engine And Engine Coolingengine Problems

1996 LEXUS ES300; SLUDGE BUILD-UP; EXCESSIVE OIL CONSUMPTION; WHITE SMOKE ON START-UP; DEALER SAYS THE ENGINE NEEDS TO BE REBUILT AT A COST OF ABOUT $7000. THIS IS THE SAME PROBLEM THAT TOYOTA/LEXUS HAS ACKNOWLEDGED FOR 1997 TO 2001 MODELS WITH THE V-6 ENGINE. WHY WON'T THEY HONOR THE REPAIR TO THE ENGINE FOR A 1996 MODEL? *NM

ENGINE CHECK LIGHT INTERMITTENTLY ON, BLUE EXHAUST IN ENGINE SMOKE, ABNORMAL OIL CONSUMPTION, GELLED OIL OR SLUDGE PRESENT INSIDE VALVE COVER BELOW OIL FILLER CAP. CALLED LEXUS AMERICA, BROUGHT CAR INTO DEALER, THEY TELL ME I MUST PAY $2,071.06 FOR REPAIRS AND PRETEND NOT TO KNOW OF THIS COMMON 3.0L V-6 ENGINE PROBLEM THAT IS EXTENSIVELY DOCUMENTED ON THE INTERNET AND THAT LEXUS HAS ALREADY STARTED REIMBURSING CAR OWNERS STARTING WITH 1997 MODELS.*AK
