Will a hole in the header cause smoke exhaust?
If you have an O2 sensor, your O2 sensor will not read exhaust gases properly which may cause the ECU to make the engine run rich. Yes. Holes close to the engine in the headers may also cause unburned fuel to ignite in the headers causing backfiring.
What would cause a constant very loud tapping or knocking noise in a Chevy 350 engine that does not blow smoke or leak oil and seems to still run good.?
Check operation of exhaust "heat riser" valve. Also check exhaust header gasket for leaks. Heat riser should be near the exhaust header, in exhaust pipe connection.
What would cause gas in the exhaust on a motorcycle?
Exhaust of an engine is a gas.
What exhaust manifold is best a 4-2-1 or a 4-1?
The 4-2-1 header or tri-y header is a better design. The design improves exhaust flow. They provide better flow by combining the exhaust gases slowly and in two parts which helps with scavaging. An engine is a big air pump the faster the air goes in and out, improves performance.They can however cause clearance issues in tight engine bays. so be carful and research before you buy!
Will a exhaust leak in the exhaust past the header cause a valve to burn?
No, that's kind of an old wive's tale anyway! The valve material is too good now.
Can a temperature sending unit cause over heating?
It won't cause over heating.....but it can go bad and send a signal that the engine is over heating when it is not.
What would cause backfir?
Exhaust leaks close to the engine.
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!
What can cause white smoke from a diesel?
Moisture in the exhaust, or a cold running engine.
Will a blocked exhaust pipe cause check engine light to come on?
It could.
Will a crack in the exhaust manifold cause the check engine light to come on?
It could.
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.
