Hi everone,
Sorry to break up the party. I have an issue that started out being a interesting issue but now is a pain in the butt. First I noticed a rattle comming from underneath the car that sounds alot l i k e a throwout bearing but the problem is I have an automatic. I also have a bad hesitation from a dead stop until about 1200 rpm. I decided to take it to a mechanic and he told me that he thinks its because of all the oil Im sucking up due to the plenum pan gasket being bad. So I got motivated and bought a new intake made by Mopar. W h i le I waited for the manifold to come in I sent the heads to be reworked and cleaned the throttle body out twice due to the amount of carbon/oil buildup. Also w h i l e waiting I changed the fuel pump for the fun of it. After the manifold came in and I reassembled everything and started her up the noise was still there but the hesitation was less. So I was wondering if a oil/carbon soaked O2 sensor can cause a rattling sound? especially with all the burnt up oil that was probably flowing through those pipes. I also forgot to mention that the cat is good and the manifold pressure is also good. I also took it to a muffler shop and got a cat back system manufactured by pypes. Any suggestions would be helpful. Im about at wits end. Forgot to ask, is there an easy way to get the o2 sensor off without buying the socket/adapter? Thaks a bunch for the help

 

I wonder if you are loosing your torque convertor???? How is the shifting????

Is the sound small or loud, could it just be a loose bolt, what about the cover on the Cat????

 

Shifting is better than ever. The sound is pretty loud. The rattle is about as loud as my exhuast. I am trying to chase it with a stethascope and it sounds like its emanating from the exhaust but not to sure. Trying to here a rattle like that is kinda hard since everything freaking ticks. Really not comfortable climbing around underneath the vehicle with it in drive. Not sure if Ill ever find it but Ill keep you posted on pregress. By the way I found why my durango was having issues with taking off ftom a start. I looked over the sensors again and noticed the IAT sensor was coated in crap. Cleaned in out really well and put it back in and it was like driving a whole new truck. Can tell a huge difference now with the new manifold and my MPGs seem to have increase also.
