I recently bought a 2002 v6 1500, and the guy i bought the truck from said the person he got it from took off the dipstick tube and never put it back on, so when I went to look i can't figure out where the tube goes back in the block, can anybody help me with the location of this?

 

its at the back of the block behind the heads. most likely have to pull the intake and you should see a hole.
