Valve train noise big block Chevy when hot?
Engine running hotter then 220 degrees can cause valvetrain noise. Bad fuel can also cause valve noise / PINGING sound. Ignition timing to high / Advanced to far, can also cause engine noise.

this is caused from piston to cyl wall clearance when engine warms up the pistons exspand and the noise is less. DON'T WORRY ABOUT IT
What would cause pinging in a 2002 Trail Blazer?
Pinging, knocking and detonation are all terms for a condition known as "pre-ignition,". That means some of the gas and air mixture is igniting in the cylinder before it's supposed to. And when that extra flame front crashes into the normal flame front (created by the spark plug), you hear a noise, and that noise is pinging. Pinging is something you want to avoid if possible. Engine damage can occur if pinging is severe. Pinging is caused by using too low an octane fuel. Use what is recommended in your owners manual. An engine out of time will also ping, so have the timing checked. Carbon buildup will also cause pinging. A product called Seafoam injected through the intake as outlined in the instructions on the can will help remove carbon and stop pinging. A defective EGR valve is another cause, and also overheating. So replace the thermostat and flush the cooling system.
Does 2002 vw passat v6 engine need 91octane fuel?
Yes. It's a higher compression engine which requires a higher octane level to help prevent "pinging" in the engine. This engine does have the intelligence built-in that detects "pinging" and retards the engine timing to prevent to pinging from occuring. Pinging is when the gas explodes early while the piston is still going up. This can cause damage to the piston over time, something that's expensive to fix. If you put 87 octane in the tank the car will detect the pinging early, retard the timing to save the engine but the fuel economy and performance goes down. Generally speaking you'll pay more in gas by dumping 87 in the tank than filling it up with the good stuff since the performance is better.
Will pinging hurt a car engine?

Occasional noise not from engine mainly while going uphill Hyundai Santa-Fe 2003 V6?
Since you don't describe the noise, I'm going to suspect that it's probably pinging from cheap gas or your timing is off just a little bit.
Pinging sound in a1995 Honda civic engine?
If there is a pinging sound in a 1995 Honda Civic engine, the engine could be out of oil. If the engine was operated with no oil for a period of time, the rings and pistons could have become damaged or broken.
Ford Taurus Oil light on pinging noise.?
This sounds like there is low or no oil pressure.Best to have oil pressure tested with a mechanical gauge.Running a engine with low or no oil pressure will cause major damage to it.
