Restriction to EGR flow
Hi there, I have a 93 F150, 4.9l engine.
While cleaning my EGR valve for the first time I noticed that there was a washer sort of thing in addition to the gasket that clearly was there to restrict the flow of the gases...is that normal? what is it for?
Thanks all
Cheers!

I'm not sure? I recently removed my EGR to clean it and it didn't even have a gasket, lol. Someone removed it in the past. I made one on the fly and it has been fine. I checked it by running the engine and operating the valve. I'd be curious to know what the "restrictor" is also...

I've seen that with aftermarket egr valves that work for a few different applications. The egr comes with a few different washers and you install a specific one for your vehicle.
