Hello everyone , I have a 2001 dodge ram 2500 with v10. 4wheell drive, automatic transmission, the truck run flat land excellent but when you go up the hill special with a trailer , oh Lord there's is a engine sound like tiki tiki sound like when you run chip gas and I noticed the I have to take out the overdrive off because of the noise, I don't know what can cause that , engine has good oil pressure in flat land run beautiful even with cruse control , I don't know , please any help I really thanks you guys

 

Welcome to DF!

I suspect what you are hearing is spark knock. So, question becomes, how old are your O2 sensors? What gas are you running? Weight of your trailer??

Moving this to 2nd gen ram tech section for ya.

 

It's pinging. Very bad. Keep OD off when towing, run at least 89 too. These engines don't have knock sensors. Welcome to Dodge.

 

Thankfully to everyone for the responded, well the manual said to put 89 octane gas , I pulled a regular travel trailer 25 ft this engine only have 132000 miles on it change oil every 3000 miles but engine runs good pressure oil , I have the filling it could be maybe timings? Maybe but no distributor , don't know ? Thanks so much for the reply

 

Spark knock is causes by hot spots in the combustion chamber that ignites the fuel prior to getting a spark from the plug. You either have to run higher octane fuel or possible colder plugs.

 

Hello hey about 02 sensor don't know how old they are , I figured they are from factory , I don't know but about weight of the trailer is a 25 ft travel trailer I will said 8000 pound

 

Ok thanks you I will try better fuel
