interior blown head gasket. you need to call a rebuild shop or a dealer immediately. Answer Another possibility is that the piston rings or the piston itself is bad and fuel is making its way past the piston/cylinder area and into the base of the engine......in either case, it needs attention ASAP.

What is that knocking noise coming from the engine?
If its gasoline it would be a problem in your head causing the piston to slap against the cylinder walls. If its a diesel engine then the knocking is caused by the .001 to .002 second delay between the fuel injector closing and the compression/combustion of the fuel
There is a knocking noise in the motor of my 1992 town and country. Could this be the transmission going?
NO. A knocking noise in the engine is a problem in the engine.
What was the purpose of adding lead to gasoline?
Lead was added to gasoline to inexpensively increase octane ratings and to also help reduce engine knocking.Increasing octane and reduce engine knocking are exactly the same thing, as the test method to measure octane of a fuel is to see when a standard engine begins knocking. The higher compression ratio the standard test engine can be operated at without knocking, the higher the octane of the fuel being tested.
Is loud knocking coming from top of engine a lifter problem or head gasket problem?
If its a legitimate knocking then you would want to go with head gasket if its a tapping you would be looking at a valve
Can unleaded gasoline be used in an engine made for regular gasoline?
Unleaded gasoline is regular gasoline. Lead used to be added to gasoline to prevent engine knocking but the practice has been banned in most developed countries. 2nd Answer: There are some engines, a lot of them not in cars, that are made to use regular gasoline. They are designed so that the lead in regular old gasoline will build up on certain moving parts, and keep them sealed against engine pressures. Unleaded gas is not good for this type of engine, at all.

Will there be any problem if gasoline was put in diesel run car engine?
Yes, if a sufficient quantity of gasoline went through it. Knock in the engine from detonation is going to be the main problem, which could ultimately render the engine useless.
What is leaded gasoline?
This is petrol to which tetraethyl lead has been added to reduce knocking in the engine. Knocking is when combustion happens at the wrong time in the engine cycle giveing a kind of metallic "ping" sound.
What would cause a ticking noise in the engine when going up a hill?
Most likely is knocking. Try next higher octane grade of gasoline.
Knocking in the bottom of the engine?
knocking noise
Is a rapid constant pinging or knocking in engine due to egr problem or what other possibilities?
Check the engine timing first. Pinging or knocking,especially under acceleration could be early detenation caused by advanced timing.
What damage is done if I accidentally put 87 octane instead of 91 octane into my 03 Aviator?
There most likely will not be any long-term damage. On this tank of gas, you may experience "knocking" or "pinging" in the engine, meaning that the gasoline may ignite prematurely in the cylinder. If the knocking is severe and/or continues for a long time, it could cause engine damage. On the other hand, if the engine runs just fine on the lower-octane fuel, then there's no problem at all.
