Does the I6 use a timing belt or a chain?
Is it a zero clearance motor?
What mileage does the belt or chain need replaced?

#1) It is a timing chain #2) Not sure #3) I don't remember reading about the chain being changed as a preventative maintenance item. :m2:

Never ever heard of one breaking and we have a few members past 200,000 miles. Many other possible things to go bad - at least we tend to not worry about timing chains.

Ah . . . time for our weekly question of "Does the I6 engine have a timing belt or a chain?"

Roadie - we need your Garfield cartoon inserted here - the one about using the search feature.
