You would get high CO's (unburnt fuel) @ idle and @ high speed, Depending on how bad and how many vales are leaking. It would fail most smog tests. You could do a compression test to see whitch cylinder is low. Hope this helps, Ben Parker, San Jose, Ca.

Why is the inlet valve bigger than the exhaust valve?
some of the gases are burnt and reduced befor going to the exhaust
What is EGR sensor?
exhaust recirculation valve, helps with your emissions
What is an exhaust gas recirculation valve?
The EGR valve takes unburnt gas vapors from the exhaust and sends it back through the intake manifold to be burnt. The EGR valve takes unburnt gas vapors from the exhaust and sends it back through the intake manifold to be burnt.
Raw gas in exhaust 92 Chevrolet van 350 motor?
Sounds like a burnt valve, the gas is not burning because of no compression due to burnt valve and gas is pushed out of exhaust unburned
What is function of exhaust valve?
Exhaust valves open at the appropriate time to allow the burnt gasses to escape.
What is the function of exhaust valve?
Exhaust valves open at the appropriate time to allow the burnt gasses to escape.
What does exhaust?
Exhaust camshaft phasing on a VVT (variable valve timing) engine is the adjustment of the exhaust camshaft(valve timing) to what the cylinder needs at that rpm/load to improve power/eff. or emissions.
What does exhaust phasing mean?

What is a vacuum modulator e g r valve?
The exhaust gas recirculation valve uses exhaust gases in order to reduce nitrogen oxide emissions, it does this by recirculating a portion of an engines exhaust gases back to the cylinders.
Will a bad valve cover gasket cause smoke from exhaust?
No, it will not cause smoke from the exhaust pipe. However the leaking oil can drip on the exhaust manifold where it will be burnt and smoke.
What is an agr valve?
I believe you are asking about an EGR valve. EGR stands for "exhaust gas recirculation". This valve recirculates the exhaust gasses back through the intake in order to better burn the gasses and cause less CO2 emissions.
What damage does the erg valve do?
Perhaps you mean EGR valve. It stands for exhaust gas reclaimer. It sends some of the exhaust back through the engine to re-burn unburned fumes for cleaner emissions.
