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!
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.
Moisture in the exhaust, or a cold running engine.
It could.
It could.
If your exhaust pipe is clogged, it can cause a buildup of exhaust gases in the engine, leading to reduced performance and efficiency. You may experience symptoms such as decreased acceleration, rough idling, or a strong smell of gasoline. In severe cases, a clogged exhaust can cause engine overheating and even engine damage. It's important to address a clogged exhaust pipe promptly to prevent further issues.
A flashing check engine light means that you have a problem with your engine that may cause harm to the catalytic converter.
