Will thicker oil stop rod knock?
Yes, adding heavier oil could mask the sound if it is a rod or main bearing knock or even a cam bearing knock but eventually you will have to add even heavier oil plus the damage done will cost much more to fix. Some modern VVT engines will have problems with heavier oil.

Can I drive on a knocking engine?
The point is that yes, indeed, you can drive a car with a knocking engine and the oil light on. … It depends on the engine, where the knock is coming from, if there’s still oil in the engine and if the oil is still circulating, even if the oil pressure is low enough for the warning light to be on.
What does a bad rod sound like?

How much does it cost to fix a rod knock?
Depending on the extent of the repair, you may need new pistons and connecting rods, camshaft bearings, timing chains, and potentially a new crankshaft. If you need all the extra parts, you’re better off replacing the complete engine assembly. An average connecting rod repair will cost anywhere from $2,500 and up.
Can you drive a car with a rod knock?
Can You Drive a Car With Rod Knock? As my dad told me about mechanical parts, “Well, it’s not going to fix itself!” And it’s true, once rod knock starts, it isn’t going away on its own.
