EGR blocker plate / leak

**lowufo** · 09-30-2008, 03:42 PM

I just installed my KD EGR blocker plate and noticed a leak when it was all buttoned up. I confirmed the leak with soapy water (cool engine, not heat bubbles). I took the plate out and saw that the thin metallic gasket is split along its length (looks like 2 gaskets, not sure if this is normal). I bolted everything back together without the plate and still leaking to a lesser extent.

Called John at KD who said I just had to play with it and that the gaskets could not be removed without taking the whole thing apart....any suggestions??

Try some gasket goo on it..Let it have time to set before you heat it up

While the goo method works its not "right".(Not busting balls. Ive done it.) If you can get a new gasket from the dealer and scrape the surfaces real well. I put the gasket between EGR cooler and the plate, but i feel there would be no problem if put on the other way. A good seal is needed so cleanliness is key!

How would you get the new gasket on without completely separating the flange?? Does the OEM gasket have slots like the blocker plate...I didn't get the feeling that mine was designed that way??

did your check engine light come on i have that fe9 in my glove box

No light, just the leak. I finally made my own gasket and placed it between the EGR cooler and the blocker plate. Much better, but still has small leak coming from OEM gasket. If I could, I'd replace the OEM gasket all together, but I don't see how I can get it out of that tight spot.

Does anyone know if a tiny leak will affect anything like my boost pressure, etc?

IF it is a very small leak you should see no problems, but if it leaks very bad you will have sluggish turbo response.

Safety wise, the exhaust side is what I worry about.

Even with an induction side EGR leak, boost will be satisfied by the MAP sensor. The turbo will just make more, at the expense of heat manufacture and added drive pressure.

I agree, skip the stick. Its sole function has you splicing into your harness to eliminate a code which has no consequences. IMO it has hurt more people (installation error and eventual oxidation) than it has helped.

I had a slight leak when I first installed the EGR blocker, I tightened the bolts a little further and SHAZAM ! The leak was gone.

My concern at the time was hot gasses possibly melting something. Since reading KillerBee's article in the lastest MaxTorque, I would also be concerned about the turbo being over worked to deliver what the MAP needs to see. (Very Bad).

What is keeping us from eliminating the EGR all together? It looks possible to remove the EGR cooler. Comments?

Tried that too...no go!! Just talked to the local diesel expert who said short of taking the whole thing apart (major pain), cleaning the surfaces and replacing the gasket, the only other solution is a home made gasket smeared with some Ultra Copper gasket goo. I know it's not the "right" way but I'm fresh out of ideas. We'll see how it goes, wish me luck
