My s10 with a 2.5 is knocking and I believe its just a wrist pin knock but it could possible be a bearing knock, the thing is when you hit the gas pedal it almost goes away and you really only hear it when the engine is at idle.

Back in the 50's, cheap car salesmen would put sawdust in the oil to quiet it down until they sold it. I am not telling you to do this, I'm just telling you what was done before. Those guys also got sued and it cost them some time.
To your question, replace the pistons and rings and the connecting rods. That should do it.

Thicker weight oil, even straight 50W racing will quiet it down, but, your putting off the inevitable, AKA rebuild. If you wait too long it'll be replace, when a rod comes through the side of the block.
fordman : Sawdust went into the rearend to quiet it. Although putting that into the crankcase would quiet the engine real good when the p/u screen & filter clogged & it locked up!..LOL!

If its a wristpin/bearing have AAA on speed dial. I had a jetski with a W-pin knock and it only lasted a few days. It could be a sloppy rocker arm or a bad lifter.

Time to stop screwing around. You will lose your engine. Never mind the "chemical" fix. There is none. A rebuild is the best answer. If you can, buy a new engine and put it in yourself. Otherwise, you have few options.

Fordman.......the sawdust only went into trannys and rear diffs to quieten gear noise...putting it in the engine oil would be suicide.

maybe try your valve lifters, valve lifters that are going bad make sounds like tick tick tick tick tick during low idle or low rpm then goes away at higher rpms. gotta remove the cylinder head for this job

Try adding a bottle of Lucas. Real good stuff.

you can run a thicker oil in it ,that will help it some,20-w-50 castrol will help make it quieter ,but if its going bad it will get louder in time,for now that might help it,good luck on it.
