EGR Delete

[jvest]

Man I wish I’d never sold my 7.3. I bought a 2005 6.0L about 6 months ago and just noticed recently I’m losing coolant. Looking from underneath it looks like it’s coming from around the back of the block between the heads. At first I thought it was the head gasket leaking since water was standing on a part of the head gasket that sticks out on the back corner, but I believe it’s actually coming from somewhere higher than that and just running down the edge of the gasket. It’s running down more on the passenger side, but it is running a little down the driver’s side. I’ve lost a gallon over the pass 3 months. I’ve not pulled anything with it since I bought it. I do drive it to work everyday, which is around 100 miles round trip each day. I'm not sure if this has anything to do with it, but my fuel mileage went from 16 - 16.5 down to 14.5 - 15 within 1 or 2 fillups. I buy my fuel at one station and my drive habits didn't change. I did try to baby it to make it better, but doesn't seem to make any difference.

I’ve read several posts about the egr valve and cooler issues. If I’m understanding this correctly, the cooler gets clogged and restricts coolant flow that potentially can causes the head gaskets issues (I assume from overheating). The egr delete is supposed to eliminate this problem. Does that sound correct? If so, is there any DIY instructions on the delete?

Thanks for the help,
Jim

Never mined! I just found the DIY instruction in the 6.0 Mod forum. I'll get this done this weekend. Does anyone know the part numbers on any gaskets, orings, etc... I'll need for this?

Thanks,
Jim

I'm not sure if anyone is looking at the thread, but I finished the EGR cooler delete this weekend. I did it a little different than the DIY instructions in the 6.0 mod forum. Instead of using the tube and o-ring flange off the cooler, I drove a 1" freeze plug in the port where the o-ring flange goes in and welded a tube at a 45 degree angle off the top of the heater core return tube next the alternator. I found at the local NAPA a 5/8" tube already with a the 45 degree bend that is used on Chrysler. I also reinstalled the EGR valve without welding. I though this would keep any codes from popping up. Since the EGR cooler port is now blocked under the intake, I did think it would hurt for the valve to open & close as it normally would. I put over a 100 miles on it today and it ran good with no leaks or fault codes.

Side Note: The cooler was not clogged (exhaust gas & coolant side), so hopefully no head gasket issues coming up. I think my coolant leak was coming from the short red hose between the block and cooler tube. The side that went on the cooler tube was loose and wet. You could easily spin the metal insert that retains the o-ring inside the hose. The other side of the hose was tight as well as both ends on the blue hose that came in the gasket kit. When I cut the metal band clamp and split the hose with a razor blade on the loose end, there was coolant between the hose and insert.
