Will an exhaust leak at the rear exhaust port of a 460 ford engine burn a valve or cause other harm to the engine?

Yes, a prolonged exhaust leak will eventually cause problems with your cylinder head. The leaking exhaust is very hot and you can cause small cracks in the head if you don't repair the problem promptly. If you can hear the exhaust leaking, it may already be too late! Get it checked out soon!

Can you really suck a valve if you run an engine with no exhaust?
Not sure what "suck a valve" means, but running an engine with no exhaust could easily cause the exhaust valves to get hot enough to melt. Exhaust valves get very hot and if you just shut off the engine with no exhaust manifold in place the cold air can cause an exhaust valve to warp, then,next time you run the engine it will not seat properly.Many people don't understand and assume that if ANY part of the exhaust system is missing you can warp a valve but that fear is just the result of failing to understand the root cause of the problem. On the other hand, a lean burning engine can overheat the valves to the point that the metal can become soft.
Can wrong valve clearance cause engine to over heat?
Yes it can, since the valves are one of parts that transfer heat from combution chamber. Other thing is that exhaust valve opened to long causes exhaust system to overheat.
What causes a 1983 Monte Carlo SS to backfire?
Well there several things that can cause this. The first is an exhaust leak. Have your exhaust inspected. The second is engine misfire due to the timing being off. In turn could cause other problems. If you have a exhaust leak at the engine, you could of burnt a valve. You may have a worn out cam shaft or timing chain. It could be a collapsed lifter, bad valve spring. The first 2 things to check are the exhaust and the engine timing. You need a good mechanic that knows these chevys for your best fix.
Name the two engine valves on a four-stroke engine?
Intake valve and exhaust valve.
What is meant by crack the cylinder valve?
The metal disk part of one of the valves (intake or exhaust, usually the exhaust as it is under the most stress in operation) in one of the engine's cylinders has cracked. This allows gasses from the cylinder to escape, causing that cylinder to be "weaker" than the other ones, increasing engine vibration. If the crack is in an exhaust valve (as it usually is), unburned hydrocarbons in the escaping gas will cause the car to fail emissions testing. If the crack is in an intake valve, very hot escaping gas can cause a type of "backfire" in the engine's air intake system.
Can an EGR valve cause shaking or hesitation?
EGR should turn on Service Engine light on 96 and later. The tube / pipe to the exhaust manifold can also become blocked. EGR could cause rough engine. Many other possibilities.
What does the egr valve on a 1998 tracker do?
EGR valve is Exhaust Gas Recirculation valve that recirculates exhaust gas through the intake manifold to improve emissions. Typically this valve has a electric connector and harness that is computer controlled. If this valve is faulty, it will cause a check engine light to appear, or a service engine light. In some cases, it will make the vehicle run roughly. Does that help you?
What would cause a 1993 grand am 4 cylinder to miss and the exhaust to become red hot?
The exhaust pipe will turn red when the engine is running lean. You may have an EGR valve problem, vacuum leak or other problems that can cause the engine to run lean. A lean running engine can burn valves or pistons and causes other problems. Whatever the cause, it needs to be repaired before you put more miles on the engine, otherwise you'll ruin it, if you haven't already.
What is valve clearance of Toyota 5k engine?
Indicate inlet and exhaust valve clearances of Toyota 5k engine
What would cause the engine to break a valve in two?
For intake or exhaust valves; Lack of oil, defective valve, bent push rod, foreign object damage, etc.
How does an engine exhaust valve get bent?
the valve bent because the piston hit it, due to a weak valve spring or over revving the engine
How many valves in diesel engine?
Three. Inlet valve, fuel injection valve, exhaust valve.
