1999 ISUZU TROOPER Engine And Engine Cooling Problems

99 ISUZU TROOPER 3.5 ENGINE BURNS OIL EXCESSIVELY. I AM ORIGINAL OWNER AND REGULARLY SERVICED PER OWNERS MANUAL. AT 50K MILES, ENGINE OIL LIGHT TURNED ON 2,500 MILES AFTER OIL CHANGE AND WAS OVER 4 QTS LOW. ENGINE NOW AT 60K MI AND BURNING APPROX. 1 QT PER 600-700 MILES. SEEMS TO BE COMMON ENGINE DEFECT KNOWN BY MECHANICS AND OWNERS, BUT ISUZU UNWILLING TO ACKNOWLEDGE PROBLEM. THOUGH MONITORING CONSTANTLY, I AM JUST WAITING FOR SIGNIFICANT ENGINE FAILURE. *TR

I GET FREQUENT OIL CHANGES IN MY 99 ISUZU TROOPER AND HAD JUST GOTTEN ONE LAST MONTH. I HAD AT LEAST 2700 MILES BEFORE MY NEXT ONE. I WAS DRIVING DOWN THE FREEWAY AND I SAW SMOKE COMING FROM MY HOOD AND ALL MY DASH LIGHTS CAME ON LIKE A CHRISTMAS TREE. I PULLED OVER AND FOUND OUT THAT MY ENGINE WAS ON FIRE. I CALLED THE FIRE DEPT TO PUT IT OUT AND GOT IT TOWED TO MY HOUSE TO LATER FIND OUT THAT THE PISTON HAD GOT THROWN FROM THE ENGINE BECAUSE IT LOCKED UP DUE TO NO OIL GETTING TO THAT PISTON. SO NOW I HAVE TO GET A NEW ENGINE WHICH COST ABOUT THE SAME AS THE CAR. *TR

FROM THE TIME I BOUGHT THE VEHICLE WHEN IT WAS ONLY A COUPLE YEARS OLD, EVERY TIME I BROUGHT THE VEHICLE IN FOR AN OIL CHANGE, THEY SAID IT WAS ALMOST EMPTY OF OIL. I BROUGHT IT IN TO A DEALER SEVERAL TIMES SINCE IT WAS UNDER WARRANTY. THEY COULD NEVER FIND THE REASON FOR IT BURNING OIL. EVERY DEALER SAID IT WAS A COMMON ISSUE WITH THE ISUZU, BUT THEY COULD NOT FIX IT BECAUSE THEY COULD NOT FIND THE PROBLEM. *JB

DT: THE CONSUMER STATES THAT VEHICLE USES TOO MUCH OIL. THE VEHICLE IS A 1999 ISUZI TROOPER. THE CONSUMER GOES THROUGH OIL, OIL AND OIL. THIS IS WHAT THE CONSUMER SPECIFICALLY STATES. THE VEHICLE HAS BEEN TO THE DEALER AND THEY SAID IT WAS NORMAL. THE MANUFACTURER HAS NOT BEEN CALLED.*AK

1999 ISUZU TROOPER RUNS OUT OF OIL. MY 1999 TROOPER THAT I BOUGHT NEW IN FEBRUARY OF 2000 AND HAVE MAINTAINED THROUGH REGULAR OIL AND FILTER CHANGES EVERY 3000 MILES SUDDENLY WAS FOUND TO HAVE NO OIL IN THE ENGINE BLOCK. THE VEHICLE HAS NEVER HAD A LOW OIL PROBLEM OR NEVER SHOWN ANY SIGNS OF LEAKING. ON MAY 30TH OF THIS YEAR AS I WAS DRIVING UP MY DRIVEWAY LEAVING MY HOUSE IN THE MORNING THE OIL LIGHT FLASHED ON AND THEN WENT OFF WHEN I REACHED LEVEL GROUND. I HAD RECENTLY HAD THE OIL CHANGED AT 72K AND THE CURRENT MILEAGE WAS 74.5K SO I STOPPED TO CHECK THE STICK. WHEN I PULLED THE STICK IT WAS DRY! AFTER DUMPING 4 QUARTS OF OIL INTO THE VEHICLE THE OIL FINALLY REGISTERED ON THE STICK! I POURED ANOTHER QUART IN TO MAKE IT 5 QUARTS AND COULDN'T BELIEVE THE...

I TOOK MY '99 ISUZU TROOPER FOR ITS REGULAR OIL CHANGE AT ALMOST 3000 MILES TO JIFFY LUBE IN COLORADO SPRINGS, CO ON THE 10TH OF MAY 2005. WHILE IN THE BAY OF JIFFY LUBE THE WORKERS' REPLACED THE AIR FILTER, OIL FILTER AND TOPPED OFF ALL OTHER FLUIDS. WHEN ASKED TO TURN VEHICLE ON, I TURNED THE KEY AND THERE WAS A LOUD CLUNK SOUND AND I IMMEDIATELY TURNED ENGINE OFF AND ASKED WORKERS' WHAT WAS THAT NOISE AND THEY RESPONDED BY SAYING THEY DIDN'T KNOW AND THAT NOTHING WAS WRONG. THEY PROCEEDED TO PUT MORE OIL IN THE ENGINE, APPROXIMATELY ANOTHER 3/4'S OF A QUART AND TOLD ME TO TAKE CARE OF THE CHARGES FOR THE OIL CHANGE, WHICH I DID. MY VEHICLE WAS MOVED OUTSIDE AND LEFT WITH THE ENGINE OFF. WHEN I STARTED IT, THERE WAS A MILD TO MODERATE RAPPING NOISE. I PROCEEDED WITH MY...

I OWN A '99 ISUZU TROOPER. SINCE ABOUT 70K MILES (ABOUT A YEAR AGO), IT HAS BEEN BURNING OIL AT A REALLY HIGH RATE. I HAVE MET PERSONALLY TWO OTHER TROOPER OWNERS WITH THIS PROBLEM WHO WERE LUCKY ENOUGH TO GET NEW ENGINES OUT OF ISUZU, BUT SINCE I WAS OVER THE WARRANTY, I DON'T QUALIFY. NOW I HAVE READ MANY OTHER SIMILAR COMPLAINTS ON THE NHTSA SITE AND WONDER WHY ISUZU HAS NOT BEEN HELD ACCOUNTABLE FOR THIS? I CANNOT AFFORD TO REPLACE MY ENGINE, NOR CAN I IN GOOD CONSCIOUS TRADE IT IN AND MAKE IT SOMEONE ELSE'S PROBLEM. I AM BURNING 3 QUARTS OF OIL FOR EVERY 300 - 500 MILES! I AM AFRAID TO TAKE IT ON ANY TRIPS TO VISIT FAMILY! I FEEL I AM BEING PUNISHED FOR OWNING THIS VEHICLE AND KEEPING IT IN GOOD REPAIR!

DT: EXCESSIVE OIL BURNING ;AND HE CHANGED UPPER AND LOWER INTAKE MANIFOLD GASKETS TWICE IN JUST OVER ONE YEAR.

1999 TROOPER WITH 3.5L ENGINE. AFTER 60,000 MILES I NOTICED THAT AT REGULAR OIL CHANGE INTERVALS, @3000 MILES, THAT THE ENGINE WAS BURING AN EXCESSIVE AMOUNT OF OIL. AFTER AN OIL CHANGE, I DROVE FROM ST.LOUIS TO KANSAS CITY, ABOUT 240 MILES ONE WAY. ON THE RETURN TRIP, 60 MILES FROM HOME, THE TROOPER SIEZED UP. NO WARNING LIGHTS, NO LOW OIL LIGHT, IT JUST QUIT. I HAD IT TOWED TO THE DEALER IN ST.CHARLES AND THEY TOLD ME THAT IT HAD HARDLY ANY OIL IN THE CRANKCASE AND THAT THE ENGINE WAS RUINED. SEVERAL MONTHS LATER AFTER LISTENING TO THE PRICE FOR AN ENGINE FROM THE DEALER $9500 AND REBUILT ENGINES THAT WOULD TAKE SEVERAL MONTHS BECAUSE BLOCKS WERE NOT AVAILABLE, I WITH THE AID OF A MECHANIC FOUND A TROOPER THAT HAD BEEN IN AN ACCIDENT AND REPLACED THE OLD ENGINE WITH ONE THAT HAD AROUND 72K MILES...

THE OIL LIGHT INDICATOR HAD A DELAY IN INDICATING HOW MUCH OIL WAS IN THE PAN. CONSUMER WAS OUT OF OIL, THEN THE LIGHT ILLUMINATED. DEALER HAS BEEN CONTACTED. *AK
