I heard a ticking in the engine and after closely looking at it, I discovered that the bolts had broke off. So I just carefully removed them and replaced them myself. Not a big deal.
same problem with exhaust manifold bolts breaking needed repair is 800+ why wont dodge warrenty this problem?
truck made a loud ticking sound when starting it up and then would only hear it when hitting the gas peddal...found out it was the manifold...found out there was two sides (driver and passenger side) and that it was going to cost me close to 300 bucks to fix! GREAT!!!!
Bolts broke off manifolds replaced them and it did it again!
BOTH GASKETS LEAK AND BOLTS BROKEN REQUIRES LIFTING ENTIRE ENGINE AWAY MOTOR MOUNTS HUGE REPAIR BILL I HAVE SPENT OVER 3000 DOLLARS TO KEEP THIS TRUCK ON THE ROAD ALL DUE TO MANUFACTURER CAUSED PROBLEMS.
Exhaust manifold bolts have broke off both sides in the last 6 months
2 Exhaust Manifold bolt broke, paid $ to have it fixed.
Now other side broke bolts, possible law suit.
runs awesome except them two rear bolts snapping off it is a serious health hazard
haven't fixed it yet - the bolt broke off. This should be considered a recall due to the possibility of exhaust fumes entering the cab (health hazzard). One part is cast iron, and the other is aluminum - no wonder they don't expand and contract at same rate.....
I replace the bolt ,and the gasket
I just broke/sheared the 2 rear exhaust manifold bolts! Noticed the loudness of the engine and realized the broken bolts when I was flushing my differentials. The dealer seems to be aware that it is a common problem on Dakotas. This should be a recall due to health hazards and possible fatalities it causes to all passengers and driver breathing in exhaust fumes. This is the result of either poor engineering or poor compatibility of metals used. Seems to be a continued problem on a wide range of years for the Dakota and still not resolved!
maifold bolts o noth sides are rusted and about to snap. The gasket on the LH needs to be replaced to stop exhaust leak. Valves could possibly become warped from issue
Clicking, rapid and sharp, coming from the exhaust manifold region of my 3.9 v6 engine in my 2003 Dodge Dakota SXT 4x4 automatic pick up truck.
broken exhaust manafold bolts
Ticking noise, engine light on and engine dies after starting in the winter. Need to rev engine to keep it going.
Took the truck in for a full exhaust replacement. They charged me for it but didn't think necessary to replace broken manifold bolt.
I didn't update the year in my first post. It is actually a 2005 Dakota, not a 1997 model year.
Truck now makes a very loud ticking on Driver's side at startup in cold weather and gradually lessens during the first mile. Not a valve ticking, but louder.
at a little over 60,000 miles the right side manifold start to make a loud popping sound when cold. Diagnose dby dealer as broken manifold bolts. drilles out and replaced now a little over year later at 75,000 miles the left side is making the same noise adn I am sure they have broken bolt heads too.
Exhaust manifold studs broke off where nut seats on manifold, both sides about half the studs.
first Two bolt on exhaust manifold broke. Removed manifold replaced all bolts and gaskets. No more leak.
