2001 JEEP WRANGLER Engine And Engine Coolingengine Problems

I HAVE AN 01 JEEP TJ WRANGLER, I HAVE RECENTLY NOTICED A DROP IN PERFORMANCE ALONG WITH SLOWLY VANISHING COOLANT. SEVERAL DAYS AGO WHILE IN TRAFFIC, THE OIL PRESSURE DROPPED LOW ENOUGH TO SET OFF THE CHECK ENGINE LIGHT. AS SOON AS I BEGAN DRIVING AGAIN THE OIL PRESSURE RAISED HIGH ENOUGH TO TO CLEAR THE LIGHT. HOWEVER AS SOON AS I CAME TO THE NEXT LIGHT THE OIL PRESSURE DROPPED AND THE CHECK ENGINE LIGHT CAME ON AGAIN. UPON RETURNING HOME I LOOKED UP THE SYMPTOMS ON THE INTERNET AND IT ALL LED ME TO A VERY COMMON CRACKED HEAD BETWEEN THE 3-4 CYLINDER. I WAS ALL TOO SURPRISED TO FIND OUT HOW EXTREMELY COMMON THAT IS. *KB

I BOUGHT THE VEHICLE IN MAY 07. 2001 JEEP WRANGLER SAHARA WITH 4.0L. @ MONTHS AFTER BUYING THE VEHICLE I LOST OIL PRESSURE. VEHICLE RETURNED TO DEALERSHIP AND THE OIL PUMP WAS REPLACED. LESS THAN 500 MILES I RETURNED THE VEHICLE TO SAID DEALER WITH A NASTY INTERNAL ENGINE RATTLE. DEALER REPLACED COLLAPSED LIFTER AND BENT PUSHROD. LESS THAN 100 MILES LATER VEHICLE RETURNED TO DEALER AGAIN WITH THE INTERNAL NOISE. VEHICLE TORN APART AND HAD THE CAMSHAFT, LIFTERS PUSHRODS REPLACED. IT HAS BEEN 7500 MILES SINCE MY LAST VISIT. I NOW HAVE A SLOW COOLANT LEAK THAT IS MAKING ITS WAY INTO THE OIL SYSTEM. I HAVE REMOVED THE CYLINDER HEAD AND FOUND A CRACK IN THE CASTING. THE CASTING # IS 0331. I HAVE SPENT NUMEROUS HOURS RESEARCHING THIS SPECIFIC CASTING # AND IT IS NOTORIOUS FOR CRACKING AND SLOWLY LEAKING COOLANT INTO THE OIL SYSTEM. MY JEEP...

2001 JEEP WRANGLER HAS CORROSION IN THE ELECTRICAL BOX, AIR BAG IS CORRODED, PROBLEMS WITH THE WHEEL BEARINGS AND OIL LEAK.*MR ON THE DAY OF PURCHASING THE VEHICLE THERE WAS A BRAKE PROBLEM. THERE WAS A LEAK BEHIND THE PASSENGER SEAT WHICH CAUSED THE CORROSION. *JB

I BOUGHT MY WRANGLER IN OCTOBER 2000, WHICH WAS A NEW 2001. UP UNTIL THIS YEAR, 2004, I HAVE BEEN LOSING COOLANT FLUID FROM THE RESERVE BOTTLE. THE DEALERSHIP WHICH THE VEHICLE WAS PURCHASED, BILL DELUCA CHRYSLER, PLYMOUTH, JEEP, INC., IN HAVEHILL, MA, TESTED IT RIGHT THROUGH MY WARRANTY EXPIRATION. IT WAS NOT UNTIL I BROKE DOWN IN CT, WHERE ANOTHER JEEP DEALERSHIP, GEORGETOWN JEEP DEALERSHIP, TOLD ME ABOUT A DYE TEST SHOULD BE PERFORMED. WHEN I WENT BACK TO MY ORIGINAL DEALER, I HAD TO ARGUE WITH THEM TO PERFORM THE DYE TEST, BECAUSE THEY WANTED TO PRESSURIZE MY JEEP...AGAIN. WHEN THEY PERFORMED THE DYE TEST THEY FOUND THE HEAD GASKET LEAKING AND TOLD ME I HAD TO PAY FOR IT. EVENTUALLY, THROUGH COMPLAINING THE THIS PROBLEM SHOULD HAVE BEEN FOUND ON MY PREVIOUS VISITS BEFORE MY WARRANTY EXPIRED, THEY DID A "GOOD WILL" JOB. I STILL ENDED UP...

WHILE DRIVING AT 65MPH ON FLAT SURFACE AND NO WARNING VEHICLE WILL SHUT OFF, AND WILL BE HARD TO START BACK UP. DEALER NOTIFIED. *AK

CONSUMER STATES THE CAMSHAFT SENSOR IS BINDING AND BREAKING, CAUSING THE VEHICLE TO STALL. *YH

VEHICLE WILL SHUT OFF WHILE DRIVING AT ANY GIVEN TIME. CONSUMER TOOK VEHICLE TO DEALER AND LEFT THE VEHICLE THERE FOR A MONTH. DEALER COULD NOT FIND THE PROBLEM. CONSUMER TOOK BACK VEHICLE, AND HAD NOT DROVE VEHICLE SINCE.*AK

WHILE TRAVELING AT OR ABOVE 40 MPH, ENGINE WILL STALL UNEXPECTEDLY, CAUSING A LOSS OF STEERING AND BRAKING CONTROL. DEALERSHIP HAS EXAMINED VEHICLE AND DETERMINED TAT CAMSHAFT WAS FAULTY. THIS COMPONENT IS ON NATIONAL BACK ORDER. PLEASE PROVIDE ANY ADDITIONAL INFORMATION / ATTACHMENTS.*AK

THE SERVICE REP STATED THE PROBLEM ARISED FROM A CAMSHAFT SENSOR BINDING AND BREAKING. I WAS A LITTLE CONFUSED SO SHE SHOWED ME THE BROKEN PART. THE PROBLEM OCCURRED BECAUSE THE SIGNAL FROM THE SENSOR WAS LOST DO TO ITS SHAFT BINDING AND SOME OF THE FINS SNAPPED OFF. THIS COULD HAVE BEEN VERY DANGEROUS SINCE IT STALLED THE VEHICLE. IT COULD OF HAPPENNED ON THE INTERSTATE DURING RUSH HOUR TRAFFIC 5 MINUTES EARLIER. DAIMLER/CHRYSLER DIDN'T SHARE MY CONCERNS AND STATED I HAD A WARRANTY. COPY OF MY COMPLAINT TO DAIMLER AND REPLY AVAILABLE BY E-MAIL.S. *AK
