To Block or Not to Block- EGR Valve

[Ryan Mikkelsen]

I am a new diesel truck owner. I have heard that it is benificial to block off your EGR valve with a plate. Is there anyone who has some knowledge or tips about this?

the first and the best thing you can do for your 6.0 powerstroke.
But get the good kit

There is no "kit" one needs to buy to block the EGR. You will need to remove the EGR up-pipe, remove the inner scoop (if present), weld a steel plate over the hole (1.5") and reinstall the pipe.

Depending on the year truck the scoop may not be there, as well as throwing a CEL after you are done. Using a custom tune with an SCT will prevent the CEL.

More than one way to go about this EGR stuff... read up my friend.

Thanks for the info. Is there any danger in blocking my EGR valve? Is there any thing I should have done before or after I do this? Do you gain any power from this block?

[pistolpete837]

no damage if done right. no power gains just makes your truck more reliable and takes out one of the 6.0's weak link

You need to differentiate between "blocking the valve" and "blocking the exhaust inlet".

The valve is on the intake side of the cooler, front and center near the oil filter housing. The exhaust inlet, which is what Heavy Assault was talking about blocking, is on the back right-hand side of the motor.

If your working within the constraints of a Ford warranty, then blocking off the exhaust inlet is the way most folks go since it can't be seen without removal of the up-pipe or egr cooler.

If you have no warranty, the best solution is to totally delete the egr cooler.

Both options will trigger a check engine light if your truck is 2004 or newer, so a custom tune for no EGR is needed to remove the check engine light.

Yes bud either replacing your uppipe with a sneaky pipe or something similar will only benefit you in the long run with a 6.0. If i ever bought another 6.0 egr block and headstuds would be the first things to be done.
