1996 Toyota Tacoma engine problems

ENGINE AND ENGINE COOLING:ENGINE

HEAD GASKET FAILURE CAUSED BY DIFFERENCE IN EXPANSION RATES BETWEEN THE CAST IRON ENGINE BLOCK, AND THE ALUMINUM HEAD. ALUMINUM EXPANDS 1.7 TIMES FASTER THAN IRON, CAUSING THE HEAD GASKET TO TEAR OR UNWRAP. TOYOTA ISSUED A RECALL CAMPAIGN AND REPLACED HEADGASKET AND FLUIDS FREE OF CHARGE.

ENGINE AND ENGINE COOLING:ENGINE

MY VEHICLES ENGINE BEGAN RUNNING ROUGH A FEW DAYS AGO AND WE BEGAN TROUBLE SHOOTING TO FIND THE CAUSE. WE PULLED THE SPARK PLUGS AND FOUND RUST AND WATER ON ONE PLUG. WE CLEANED THE PLUG UP AND REINSTALLED IT AND RAN THE VEHICLE TO TEST IT. IT RAN SMOOTH FOR ABOUT 10 MINUTES THEN BEGAN RUNNING ROUGH AGAIN. WE HAVE DETERMINED THAT THE HEAD GASKET HAS FAILED. WE WENT ON THE INTERNET AND LEARNED THAT TOYOTA HAD ISSUED A SPECIAL SERVICE CAMPAIGN FOR OUR VEHICLE BACK IN 1999 AND AGAIN IN 2001. THE LAST ONE HAD AN EXPIRATION DATE OF NOVEMBER 30, 2004. I PURCHASED THE VEHICLE IN 2002 AND WAS NOT AWARE OF THE SERVICE CAMPAIGN UNTIL WE FOUND IT ON THE INTERNET YESTERDAY. WE NOTIFIED TOYOTA AND THEY TOLD US THERE WAS NO RECALL OR CAMPAIGN FOR OUR VEHICLE. WE HAVE DOUBLE CHECKED THE VIN NUMBER WITH THEIR CAMPAIGN NOTICE AND IT IS A MATCH. WE HAVE NOT REPAIRED THE VEHICLE AS WE FEEL THAT TOYOTA SHOULD MAKE IT RIGHT DUE TO NO NOTIFICATION WHEN THE CAMPAIGN WAS ONGOING.

ENGINE AND ENGINE COOLING:ENGINE:GASOLINE

I COMPLAINED OF A RAPPING, TAPPING NOISE IN ENGINE ON 8/26/97. TRUCK HAD 15877 MILES ON IT. WAS TOLD NOTHING WAS WRONG. I AGAIN COMPLAINED OF NOISE 1/29/98. TRUCK HAD 21851 MILES ON IT. SOUNDED LIKE TAPPING NOISE COMING FROM TOP OF ENGINE . SAME NOISE AS BEFORE. THEY SAID NOTHING WAS WRONG. AT 56500 MILES TAPPING GOT SLIGHTLY LOUDER. I AGAIN COMPLAINED OF NOISE AT BEGINNING OF DECEMBER 2001. I WAS TOLD THEY COULD HEAR IT THEN (AFTER WARRANTY HAD EXPIRED!) THEY TOLD ME I HADNT CHANGED MY OIL AND IT WOULD COST 4400 DOLLARS FOR A NEW SHORT BLOCK. I KNEW I WASNT AT FAULT. I REMOVED ENGINE SO I COULD DETERMINE CAUSE OF NOISE. THE PROBLEM IS A DEFECTIVE CRANKSHAFT. IT IS NOT MACHINED CORRECTLY. IT IS NOT DRILLED THRU TO ALLOW THE FLOW OF OIL THRU THE BEARING. I SHOWED THEM THE CRANK. THEY ADMITTED IT WAS A FACTORY DEFECT. THEY WILL NOT PUT IT IN WRITING. THEIR MAY BE THOUSANDS OF OTHER TRUCKS WHOSE OWNERS ARE GETTING RIPPED OFF FOR THE COST OF A NEW ENGINE. THEY WILL BE TOLD THEY DIDNT CHANGE THEIR OIL. TOYOTA WILL POCKET ALOT OF MONEY. THE OWNERS WILL BE COMPLETELY UNAWARE OF THIS MAJOR SCAM. TOYOTA MUST ADMIT IN WRITING THEY WERE MADE AWARE OF THIS. THEY MUST BE HELD ACCOUNTABLE. THIS IS A SERIOUS SAFETY HAZARD. THE ENGINE COULD FAIL IN TRAFFIC CAUSING SEVERE ACCIDENTS.

THE ENGINE MAKES A LOAD POPPING NOISE WHILE IT IS WARMING UP AND WHEN IT IS COOLING DOWN AFTER THE ENGINE HAS BEEN SHUT OFF. I WAS TOLD BY THE DEALER THAT IT IS THE CHARCOAL CANISTER.
