Is EGR a non-issue on 6.4s?

[NRHS Sales]

I know there has been lots of discussions about doing EGR bypasses on 6.0s. But I do not see that discussed with the 6.4s. Is it a non-issue on 6.4s?

i honestly haven't met a lot of people that have done this. i just dont think its as big of a deal as it is with the 6.0s. most of the people that i've talked to, just get some egr block off plates for about $40.

EGR block off plates for their 6.4s or are you referring to the 6.0s?

No they make plates for the 6.4's as well, but they aren't a great idea. They really increase the drive pressure, and that can make blowing a Head Gasket easier. Plus, if an EGR cooler leaks, you're still going to lose coolant. The plates just prevent it from entering your engine.

I would check with your tuner mfg and see what your tuner is doing with the EGR valve.
Just keeping it closed all the time may cause it to stick shut. some tunes of tuners cycle the valve during idles, which should "clean" the valve.

thanks for the info. No EGR block off for me, just the dpf/cat delete is what I will do,

thats what i did/would recommend.

My truck is going in for its 2nd egr valve in 130,000km. It was done just about 2 years ago for the first time after 100,000km of running stock/superchips. I have been running RCD tuning and a delete pipe for just over a year and it cycles the valve during idle but it still seems to stick. That being said, my truck sees very little to no idle time. I don't even warm it up in the winter time.

IF you have Tuned and DPF delete the EGR will eventually coke up and fail. Even know the tune may move the valve, it will still get stopped up as the the soot will gather and restrict movement, its only a matter of time. The EGR block off plates will keep coolant out too. The pressure+temp is so minimal you will never notice the difference. It will give you a bit of fuel mileage increase though +.5 to +1-2 mpg.

so if you're planning on tuning and deleting DPF/DOC, then EGR block off plates are the way to prevent clogging up?
