Could a faulty EGR valve cause your engine to run to lean?
Yes
What happens when a vacuum line is broke on a PCV valve on a 305?
The vacuum leak will cause the engine to run lean.
When does a power valve operates?
There is a "power valve" in carburetors that richens the air/fuel mixture when the throttle is suddenly opened to prevent a lean condition, which would make the motor stumble.
What would a bad EGR valve gasket cause?
Poor performance, poor economy, rough idle, lean burn causing valve or piston problems...
On a 97 deville can erg valve cause the engine to overheat?
It is possible if it was putting too much exhaust back into the engine causing it to run lean. I'd check for any computer codes for the EGR valve. They should tell you what is wrong.
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.
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.
What would cause a loud knocking noise in engine upon starting?
Running too lean.
Where is the ERG valve on Ford Fiesta Diesel?
as u lean over engine on right hand side under fuel filter block.
Will two stroke oil damage a four stroke engine?
while adding top end (valve train) lubrication, the oil will lower the octane rating of the fuel being used, cause massive carbon build-up, possible plug fouling, and lean mixtures that can cause overheating.
What will happen if oxygen is supplied directly to carburetor other than atmospheric air?
This would cause an extreme lean condition which would lead to severe engine damage, such as melted pistons or valve seats, burnt valves and blown head gaskets.
What can cause lean fuel mixture and?
A vacuum leak can cause a lean burn.
