Rod knocking?
Is there a way of testing for a bad rod? My truck has developed what sounds similar to a rod knocking noise when sitting at a certain angle or sometimes when you hit the gas from a stop.

make sure is is coming from the bottom of the engine. it could be a lifter tap. how is your oil pressure? is sounds l i k e it is starving for oil by the way that you described it.

take a 3/8 steel rod, put bit against each cylinder and your ear. if its only one cylinder its probably the rod. if its everywhre than it could be the o2sensor. mine ran rich and it sounded like a bad rod.
