1998 Jeep wrangler exhaust manifold cracked. Contacted dealer to check about recall info after repair shop said this was common in 1997 and 1998 wranglers. No such luck. Had it welded at my expense and have since spoken to many other folks having the same problem. Should be investigated. *Nm

I have a 98 tj jeep 2.5Lt with on it 57,000 now. What I experienced was a major power loss in the while getting on the freeway. The symptoms were as follows. The engine would rev up but the rpms & speed would rise slowly. I though maybe the clutch was slipping and pulled off the freeway and drove it back home . I noticed it got worse and the engine was running poorly at idle and if you gave it gas it would bog down and die. I also noticed strong exhaust fumes and very little pressure from the exhaust pipe. So I...

INTAKE MANIFOLD CRACKED. *AK

Exhaust manifold bolts are snapping off in the block of jeep 2.5 4 Cyl engine. This problem is documented by chrysler as a design fault problem but they will not cover it. The problem has not been repaired yet because chrysler will not cover it and it is a very expensive fix that can't be afforded at this time. The problem is also a safety problem due to the fact that the exhaust is leaking from between the manifold and head and could get into the vehicle. The problem was first noticed in about jan 02. The vehicle...

EXHAUST MANIFOLD LEAK. *LA

1998 Jeep wrangler, 4.0L. These two issues are on service bulletins, but should be recalls. The first issue occurred as my wife was driving when the valve springs snapped, stopping the car in the middle of the interstate. Discussed in detail on service bulletin 182298, initially issued before I even purchased my car. It was very frustrating to find out that jeep was aware of such a dangerous issue and did nothing to prevent such failures from occurring. The second is a very widespread and documented problem...

1998 Jeep wrangler 4.0L, exhaust manifold crack at 30,000 miles. Jeep/chrysler refused to fix, stating only catalytic converter covered under warranty. Crack occurred in a weld joining the two pipe, almost 3/4 of the way around the pipe, causing cosiderable noise, and loss of power. Guages fail periodically, but come back on there own, after a few minutes. Air conditioner drains onto floor inside vehicle on long drives and can even short out the radio. The steering column also sqeals like an old door when its cold outside.*Ak

A cracked exhaust header caused exhaust fumes to enter the passenger compartment of the vehicle. *Nlm

I have had numerous problems with my jeep wrangler 1998. This is a partial list I sent to chrysler: I bought my jeep with just 3600 miles on it from a dealer in 1999. From day one I started experiencing problems. Many of them I returned to the service department. Some they were able to fix, others, after many return trips, they were 'unable to duplicate the problem'. 1. Gauges would stop working while driving - I brought the vehicle in 5 times before they were able to duplicate and finally fix the problem. 2. ...

Exhaust header cracked & broke in two will not pass state safety inspection or emission

Cracked exhaust manifold. The crack could have resulted in carbon monoxide entering the passenger compartment. Repair facility reported that this is a common failure in 1997 and 1998 jeep wranglers. Manufacurer paid for parts. Dt

The mannifold has cracked twice. The first time, jeep fixed it, stating there was a "design flaw". Now, approx. Two years later, and another 32,000 miles(roughly) the same thing happened again. This time, they would not fix it, due to mileage. However, I feel as if there is a design flaw, and this happens every 30,000 miles or so, someone should be aware of the problem and attempt to correct it. I just had it fixed for the second time and the cost was $600.00. Nlm

EXHAUST MANIFOLD CRACKED NEAR THE FLANGE.*AK

I took the jeep last year to get the rattle fixed. They fixed it, but on the 1/12/02 I took it back for the same rattle. I don't believe they fixed it, just tightened the linkage up. My wife and I spent 7 hours at landers without anyone contacting us about what the problem was. They also broke a bolt off in the block that holds the exhaust manifold on, again we weren't informed. Our warrenty covered the exhaust problem, but landers said that the linkage wasn't covered even though they had worked on the linkage less...
