What makes a 350 spin counterrclock wise?
Preignition.
What is a kocking sound in the engine and go away in a minute or two?
Preignition. If timing correct, you need more octane in your fuel.
What are some of the symptoms of engine knock in a 77 Trans Am other than a knocking sound?
Engine "knock" is preignition or detonation of the air-fuel mixture before the piston is in power stroke position. It is usually caused by a lean fuel mix. So to check for preignition, check your plugs for signs of lean running.
What is knocking noise on 350 Chevy at 30 mph and above after warm up but does not do it at idle?
Sounds like preignition. A higher octane gas might help
What is a knock sensor for?
It senses preignition or pinging and adjust ignition and sometimes fuel/air to prevent it. Pinging is the sound you get when driving a standard up a hill in to tall of a gear

What is the difference between preignition and detonation and how do they cause engine damage?
They are the same thing. They cause damage by applying the force of combustion to the piston before it has reached the top of its stroke, which basically pushes it "backwards"
Can you run the truck with knock sensor code?
You shouldn't knock is detonation -preignition for some reason, possibly a timing issue. Exploding gases in your cylinder at the wrong time can possibly break pistons.
How many general types of combustion chambers are used in diesel engines?
Diesel Engine combustion chamber types : Swirl port combustion chamber type and Preignition port combustion chamber type.
What symptoms caused by faulty timing on harley?
Too far advanced: Spark knock (also known as preignition), Hard starting, Damage to pistons, and Poor Performance. Overheating and very sluggish performance.
Is it a big problem if the EGR Flow needs replaced on a 2001 Toyota Camry?
Replace the EGR valve. It routs 1200 degree exhaust into the 1800 degree combustion chanbers to decrease preignition and reduce nox.
What is preignition of fuel?
Pre-ignition of fuel that occurs in a spark-ignition engine is when the air/fuel mixture in the cylinder ignites before the spark plug actually fires. It can be initiated from a hot spot such as in the combustion chamber.
