I have a 2005 ram 1500. When I bought the truck the guy told me it just had new timing kit installed, well long story short it didn't after all . My question is when I took the timing cover off I noticed there was no bolt in the idler sprocket. Is there suppose to be one . Everything I found online says there is and it's supposed to be torque to 25 ft/lbs. Could this be the reason it's not running right Andi have lifter rattle, oh and it's a 4.7l by the way

 

Yeah it should have a bolt. Here is a pretty good video on getting things all lined up... the link starts at the bolt you asked about, but be sure to watch the whole thing

 

Thankyou that was very helpful.
