Answer: Could be gas grade 86-91 octane, because it happens via temperature change. Gas is refined differently for the season's temperature. More than likely its the lower grade gas you are using.
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.
that sound is caused by hot air causing the metal pipes to expand. Pinging is caused the exhaust valve closes before all the exhaust gases are out and the intake valve opens and new fuel enters. One of the best ways to fix it is to adjust your timing, or change your fuel octane to a higher one.
lean ping ,,,vw's good for that ,over time the engine becomes lean and out of adjustment ..its a setting with the injected vw's. makes the engine run hot also ....
Your blood will be at body temperature. that's how hot it will be. When mammals experience a temperature equal to their internal body temperature from the outside, it will feel hot on their skin.
Most probably the noise is piston slap, this noise is heard when the engine is cold and disappears when the engine is hot. if the slap is very strong when the engine is cold and the noise becomes less when hot but still the noise can be heard.
as long as you like just watch for the sun its made of fire (very hot)
It becomes humid
If you have newborn kittens outside and it is very hot outside, well, bring them inside! But, if you can't, get a fan to cool them off and make sure they are in plenty of shade! The mother should provide them with whatever else they need, and just hope they will make it
Car : If outside hot, you will not get hot If outside rainy, you will not get rained Motorcycle : If outside hot, you will not get rained If outside rainy, you will not get hot
the air can have very little moisture
You can say "Il fait très chaud dehors" in French to express that it is very hot outside.
