EGR Question

[smuesse]

This Past weekend wile installing my exhaust i pulled the EGR up pipe and cut it and welded up. So now the EGR is not getting any exhaust. Before that i had unpluged the EGR valve. So my question is, what if my EGR cooler was already failling, will it just fill up the intake with Coolant? With no exhaust coming in and the EGR valve shut, it seems to me like it would fill up the intake, so im conserned of how i would tell if my Cooler is bad with it capped off.

Do you think it is currently bad or are you asking if it goes bad in the future?

When mine went bad I saw coolant goop when I looked at the bottom side of the intake like down beside the alternator. Another place to look is straight down on the top of the motor where the small hose connects to the oil cooler. Orange or blue hose about 3inches long.

Last night i checked it over good and the coolant loss is getting to be more. I checked the Orange hose and its fine, its totally dry on top of the engine. But if you crawl under the truck you can see where it has ran down from behind the Right head. The only thing i have changed is blocking off the EGR Cooler. So what im wondering is if its not bad and leaking. Im sure i didnt get a good seal when i put the cap on the exhaust inlet. I guess i need to check it when the engine cools and run my hand around the EGR cooler inlet to see if there is any antifreeze. Thats almost what it has to be, because it was loosing coolant before i just coudlnt fine where, now with the EGR Cooler blocked and not sealed it can leak down the back of the engine.

I would suspect that it is probably bad. The orange hose is the old style they have a new one that is blue. So I am guessing it has never been replaced. I saw your other post about deleting it all together. Someone here has done it but can't remember who. Ever since I've had mine blocked off no more problems out of it. So maybe put a new one on and go on.
