TSB=tech service bulletin I believe.

 

using synthetic will help alot... if you feel it's sludged up already you might try MMO, it should clean the insides pretty well.

 

what is MMO?

 

marvel mystery oil... it's the bomb. do a search for it over in the 2nd gen ram forum and you'll find lots of info on it.

 

Thank you

 

Correct!

IndyD

 

Does it also effect the 3.7L V6 which is based off of the 4.7L?

 

I haven't heard anything on that but you may want to ask around in the Dak sections they would hear about that. They only made a few D's with the V6's (not sure if that is the 1st, 2nd, or both gen D's though)

 

They first offered the 3.7L in 2004, right at the end of the second gen and starting the 3rd gen. Info will be limited, but they complain alot about the engines being noisy when the first start, similar to the sound of a diesel engine.

Is this oil sludge problem as wide spread and bad as the one that effected the 2.7L V6 in the cars?

 

I have heard it isn't too bad from Indy and It's not a huge problem from what I have seen on the forums but it is present.
