EGR valve replacement?

[HOOGENRAAD]

How difficult is the egr valve to replace on an 08 6.4? i have read about this special rotunda tool to remove it. I will be replacing the valve with a new one so it doesnt matter if it gets damaged removing it. Thanks for helping!

You are likely going to need the housing that the EGR valve goes into also. I tried to take one off a truck with 19k miles on it, and it was seized in the housing. Broke the tool, valve, and housing.

It's a very poor design, interference fit with no gaskets.

You need the puller to make an attempt at getting it out. I have had some luck using an air hammer to get them out, also.

Why are you doing this on your own? Do you not have any warranty left? The housing is somewhat expensive, and it's fairly difficult to change, there's a bunch of tubes and crap in the road for a couple of the bolts, and ideally you should remove the vertical EGR cooler to get the housing and gaskets and junk all oriented properly.

Truck is out of warranty by mileage, that why i have to replace it instead of warranty. Kinda sucks How long on average do you spend to get one replaced?

as hillbilly said, these are PIA to change. Mine plugged up at 10k miles and it took 2 weeks to get changed. THey broke two rotunda tools in the process. It looks like 4 vise grip clamps welded together, freaky looking tool

Wouldn't the egr valve be considered part of the emissions? Aren't they warrantied to 100k at least? Just thinkin...

I live in Canada. Think the warranty was 5 years or 160,000km (100,000 miles). What is book time to change the complete assembly Hillbilly? I am not looking forward to this job. First one is always the worst. Our fleet of trucks are all powerstrokes, i personally own a duramax. I am learning all the problems related to these 6.4 thanks to this site. Thanks for the help!
