1. What are the symptons of a car running lean and how could I find a solution to it?
2. Of an engine running "hydraulic"?
3. What is "detonation" I keep hearing this word.
4. What breaks or blows when you blow your engine?

I'm trying to clarify some things. I'm getting terms mixed up.

 

1. Your spark plugs will look like they have white flakes on them.
2. don't know exactly what you mean there
3. I believe it is when combustion takes place when not enough fuel is present
4. anything can blow and break the motor
rod bearings
valves
rings
head gasket
etc.

 

detonation is where the air/fuel mixture is exploding prematurely (that is before it recieves spark from the plugs, pistons dont like that)

 

By hydraulic, do you mean hydro-lock? That is when the engine ingests a large amount of water through the intake and into the combustion chamber. Usually leads to number 4 on your list.

detonation: The action of the fuel charge firing or burning too violently, almost exploding. It sometimes results in a noise called "pinging." Detonation is caused by autoignition of the "end gas" i.e., that part of the charge not yet consumed in the normal flame-front reaction. Detonation occurs because piston motion and compression of the end gas raise its temperature and pressure to the point where the end gas autoignites. The pinging or knocking noise is the result of intense pressure waves in the charge which cause the cylinder walls to vibrate. Also called "fuel knock."

blown: [1] An engine equipped with a turbocharger or supercharger. [2] An engine which is ruined. Usually the piston is seized. Also see blown head gasket.

blown head gasket: A gasket that has a break between the opening for the cylinder and an opening for the coolant. The coolant will leak into the combustion chamber. This condition can be diagnosed by a loss in coolant and white smoke out the exhaust.

do by Hydrolic you mean: a Hydrolic tranny??

 

props to you rpr

i couldnt have said it better.
