2000 jeep 4.7 rod noise but rods and bearings are fine what could it be?

I could be a bad wrist pin. They will sound just like a rod. Try letting it idle and pulling the plug wires one at a time. When you hit the one that has a problem the noise will go away or almost away. Then you can take that rod cap off and check it for a spun bearing.

Why does low octane gas make an engine knock?

Low octane gasoline ignites at a lower temperature/compression than higher octane gasoline causing it to (depending on circumstances) ignite before the spark happens. This "preignition" or "detonation" causes excessively high cylinder pressure in the combustion chambers and at piston-to-connecting-rod near TDC and typically produces a knock noise which. The preignition or "spark knock" can also damage pistons, valves, connecting rods, and bearings. Repairs may require rebuild of the engine.


What causes rods to knock in a motor?

Usually worn out rod bearings. This can be caused by wear or repeated pinging. Usually, if there is knocking in the engine, you are not getting adequate oil to the engine. What is happening is that there is no oil to lubricate the rods and pistons as they are moving inside the head and so it is causing the knocking noise. If you have filled you oil and still hear the knocking, the main filter in the oil pan could be clogged. This happened to me. You do not want it to go on too long because you will blow your engine.

What does bent rods sound like on a 350 engine?

If you are talking about the PISTON RODS then they will not make any noise. The engine will just wear the pistons and cylinder walls until you have a problem with oil comsupition. If the push rods or bent then you will have a engine miss and rocker arm noise in the valve covers/ clatting noise.
