I've used both...they're both quality products. I run a heat-treated Cloyes
though.

I will likely go ahead and replace my chain when I do the next water pump
anyhow and won't have to fuss about it. Bernd, do you still like the Cloyes
or Edelbrock chains?

Being an "Old School" DC Tech, about the same time as changing the chain on
an LA block...just make sure you also get the updated tensioner along with a
new chain.

On the O2 sensor, they normally will last about 60-70K miles. Anything
beyond that and the performance of the O2 sensor will degrade. Best
recommendation, change it at 65-70K miles. Reset the PCM as well after the
new O2 is installed.

What's the (approx.) time given to replace the timing chain? Anything
procedures or problems unique to this motor?

My '95 3.9L has 106,000 and I'm strongly considering replacing the
chain. It makes some noise ... enough that you know it's a Dakota
without looking, but it's not terribly loud or obnoxious.

Second question: What are the thoughts of the group on replacing O2
sensors. AFAIK, my truck has the original. I was trained and worked
as a mechanic and was certified as a Chrysler Master Mechanic, but
that was in the early 1970s. There are more than a few changes that
I'm not too familiar with!
