I have been hearing this ticking/knocking noise in my 96 s10 v6 blazer, I have seen several mechanics, have of them say its the rod bent or something, causing the lifter to tick, others say its just the lifter, i'm to cheap for a noise diagnose test, so is there a way of telling which one it is?

Lifter sound usually sounds more frequent (fast) than bottom end problems because it's usually more than one.
Lifters tend to quiet down at slow speeds and get lowder with acceleration, whereas rods will knock loudly at slow speed.
Try using a gunk disolver in your oil followed by an oil change with a heavier grade of oil (10W 40). This may solve sticky lifters.
Also put your ear close to the valve cover at the top of the engine and listen will the engine is rev'ed to isolate top end sound (lifters). Then listen at the oil pan for connecting rod/piston problems.
Bottom line...If your too cheap pay for a diagnosis than you probably can't afford an overhaul in the event that it's connecting rod or piston problem, so que sera sera...why sweat about maybees.

Ok I can understand your frustration. If it is a lifter it will tick-tick-tick.
If it is a rod, it will knock knock knock
See if this helps. If lets say you take a empty can and hit the inside with a stick this is what generaly what a rod sounds like.
But lets say you tap the top of the can with a stick this is what a lifter sounds like.
A lot of times a lifter tick just means it is sticking and doesent mean much
If you do have a rod knock it can come through the block if you dont fix it.

A slight ticking noise could mean a collapsed or stuck lifter. A louder knocking noise is more serious as it could mean a connecting rod or bearing is going south. Either way, you're looking at a "not inexpensive" repair, although the lifter is cheaper, since that is basically "top-end" work rather than a complete engine rebuild (or replace!).

Well I can tell you one thing, if it was a bent rod, that motor would not be running. Stay away from that inept mechanic. A light tick can be anything from a bad belt to a worn lifter, the only way to tell is to pay to have it checked by someone competent.

take the valve cover off the engine. have some one start the engine, and let it idle. pour clean oil down ware the push rods come up through the head. if that shut's up the ticking, then it's just lifters.
If there is a bent rod you will see it. as the rods go up and down, they also spin. a bent rod will not spin, it will just move up and down
