Ironically I just bought a plate from that eBay store a few hours ago. I figure its a killer deal considering it comes with a new gasket which I'd have to replace if I were to just clean the EGR ya know?
I'll throw a picture up of it installed when it comes.
Sounda Barrier - What are the bolt heads like? Hexagonal socket drive? I have to buy a socket for that if they are.
That's all I did. Picked up a piece of scape at work, traced the gasket, then cut and drilled it. I didn't have to make it the exact shape as the gasket but work was slow so....wth right....Can a plate not be cut out of aluminum and a gasket made with black high temp RTV silicone? You could likely use the bottom of a coffee can and go for years before having any sort of problems. Just a thought. You won't get any show points for a custom billet cnc'd part burried beneath a dead valve.
Mine crapped out last night and lit up my cat like a candle. I'm putting a blocker plate in today after messing with these things for years I've had enough. Screened gaskets help the most but it seems that sooner than later a cleaning, rebuild, replace, or guzzle beer, swear, and repeat will be in order.
You did it right R.I.. Just plugging the EGR port does not account for the lean-out routine when the ECM commands EGR function. If you're having rough idle problems related to a stuck or leaking EGR valve, replace it. Simply blocking it off causes a lean condition under cruise that is likely to shorten ex-valve and seat life. To different degrees, the ECM adds timing and reduces fuel when commanding EGR opening. To do it right, you should have the EGR function disabled in the chip/flash when you use a EGR block-off plate.I left everything in place and had the EGR turned off by wait4me performance
