Troy its common enough to write an article about it . Click here.

 

Thanks for the link. I pulled this up the other day but forgot where it came from. Between you browsing on my phone, home laptop, or other computer I lose things sometimes.

 

Thanks semperstrokin...

EGR marbles is caused by a slow leakin EGR cooler.

 

I'm in denial

 

I agree the EGR is worthless

however, deleting it causes issues with certain trucks. Especially those with the latest PCM strategies from Ford (06 & 07's...and earlier's that were updated). It causes the fan to act wrong...if not at all.

I have my EGR turned off with my SRL tune. I'm sure a little gas flow still exists past the valve, but nothing like when it's operating per factory spec


If I ever have to get inside the motor, I plan on getting the BPD round cooler.

 

What's strange is when I changed the EGR valve my intake manifold looked dry and I typically change the coolant every 2 years and the coolant level never drops one bit.

Now that I thought about it a little more the shape of the carbon chunk had to be formed in the intake manifold (one side being very flat) and not the EGR cooler itself.

 

Troy I'm in the same boat. No coolant loss, no wetness in or around the valve, and the chunks were flat on one side. I'm going to call them wafers.

I was thinking it would be interesting to have them analyzed somehow to see what their make up is exactly. This would be the only way to rule out whether or not they contain coolant in them, but to be honest I don't see how they can.

 

As long as the EGR Valve is Plugged in it shouldnt affect the Fan. plus keeps PCM Happier.

Im deleated but the egr valve is installed and Plugged in and ZERO Fan Issues

 

Sounds like the way to go if you do the delete. I was under the impression the fan issue was still there for some reason. It is something I haven't looked into too much. I always figured I would just replace the egr/oil cooler at the same time and most likely switch to a non silicate coolant.

My main concern if I delete the thing is getting inspected. I don't need that headache. What do you think of the sneaky delete setup instead of a full delete?

 

yeah, but then you have that thing sitting out there in the open. I like the idea below if going the delete route
this is the Win/Win option if you want to delete. Get the exhaust port welded shut on your EGR cooler and the sneaky up-pipe will remove the EGR scoop.

I've read several cases where guys see cooler EGT's and quicker turbo spool time with that scoop/up-pipe change

 

So if they plug into the OBII port will they see that the egr is non functional or not ???

I have thought about it, but here in Calif you have to bring it in every 2 years after truck hits 4 years old.

Can it be done ??????

 

Any CEL is an auto fail so without tuning I don't think it would pass. I would think there's a way to get around it by loading a tune to fool the PCM.

 

My advice is to not worry about the analysis and just save your money. If your concerned about this issue causing you to be stranded, just carry a spare EGR valve and a small crow bar behind the seat and your golden!

 

My old valve is cleaned and ready to go with a new gasket kit.

Interestingly, getting the carbon wet with water completely changed them. It formed black sticky paste.

Think about it. If you sent the pieces to be analyzed an knew you didn't have a leak, would that be worth it? Especially considering the time and money it will take to replace your coolers. And thinking about it every time you're on a trip out of town wondering if your egr cooler is going to pop. I'd be willing to pay a couple bucks for some piece of mind. That's what the sgii is all about.
