Well after 75 miles on the new engine (with stock ECU), I've had no check engine light from the EGR block I did before I installed the engine.

Heres how I did it.

1st the EGR system is all supplied by cyl #4


You can see in this pic how it the gases get to the EGR valve.



The valve itself (you'll need a new gasket after pulling this off).



Once open the valve feeds all cyl with exhaust gas



To block the system I used a piece of old head gasket but anything thin and metal will work (aluminum can cut up would also work). You can see the gasket plate is a two piece metal gasket.



To seal everything up, I put Permatex Copper Seal.



You can see it here on the opening that seals the blocking plate to the upper portion of the EGR dist system.



Here it is installed



You can see since this is downstream from all the EGR valves and solenoids, the system has no way of knowing the exhaust gases arent making it into the engine.

Dumb question: Why do you want to disable the EGR? Combustion temp goes up.

 

Its for turbo'ed vehicles. You dont want those hot gases recycling if your turbo chargerd. AND ...NA, you dont see a hp gain or loss...so its fine. It keeps your IM clean of all that unburnt shit.

 

Won't that cause you to fail the emissions test? The gasses don't come out as clean?

Maybe I'm just being dumb...

I guess if your turbocharging you're probably racing anyway.

 

I just had the EGR valve changed last week at the stealership. My question is: Im hearing a whistling noise everytime I step on the gas. Is this norm?
