EGR Block Off/ Bypass?

Ok, I've seen a few inquires on this issue, but no definite answers on it.

Has anyone tried the EGR Block off plates with coolant bypass?

I think this is the way I want to go. One, due to warranty, and two, emission testing every year. If I were to do the coolant bypass; what hoses on the coolers do I have to disconnect so I can re-rout the coolant lines (capping them off at the coolers) and re-routing the hose straight from and back into the engine, skipping the coolers?

What my thoughts were, I'd take a section of coolant hose and bypass the coolers, running a new section of hose to the two points on the engine. I'd then just cap off the points where the lines ran into the coolers. I'd also obviously block off the coolers with plates.

Does this sound like I'm on the right path???

Is there someone who could put up a diagram showing which lines I have to re-rout from the coolers when I disconnect the hoses, and then bypass the coolers.

I've read that the blocker plates alone will not do the trick and there is still a propensity that the coolers could burst and leak coolant into the motor leading to major issues!!!

This is my best option I think...

Any opinions or ideas?

Thanks

Iv been having the same issues as you with the coolers and losing small amounts of coolant. Been to the dealer several times no luck. The warranty is such a joke that im just thinking about deleting and being done with it.

Yea I hear you. I've been to the dealer and shown them my Black Stone Report stating there's coolant in the oil. They said everything looks fine, pressure tests held, and the amount of coolant is minimal... They also said your going to have a little coolant/ fuel and oil mixing together as that's what happens with a diesel engine... (REALLY???)

My service adviser said, "bring the truck back in if something breaks and I'll try (TRY) to have it covered under warranty." Keep in mind my truck is bone stock, with 47,000 miles on it and two years left on my warranty, and we'll TRY and cover it when it breaks???

Didn't give me a good and confident feeling in my dealership...

This is why I'm leaning towards the preventative measurements (DPF/EGR delete) or block off regarding the EGR. My only kicker is I have yearly emission testing. This is why I'm asking about the block off and re-rout?

Or can I install blocker plates and then just use the plugs the delete kits come with when removing the coolant lines while leaving the coolers in place. I'd then cap off the coolant points on the EGR coolers until I needed to test the emissions then reconnect everything...

Just another thought in my head.

Not sure on the egr bypass. But i would do the dpf/doc delete. Best thing i ever did to my truck. I can have the whole exhaust swapped out and back to stock in 45 min.

Yes, DPF is coming off for sure in the next few months.

Here's a diagram of my thoughts for an "in-place EGR delete" I have two different thoughts...

#1 Is to use blocker plates and block off the coolers at both ends to stop the exhaust flow. Next take the coolant hoses off both vertical and horizontal coolers and cap them off where the hoses connect to the coolers (green dots on diagram). Next I would get a section of heater hose and re-rout the coolant, basically skipping the coolers by re-routing the coolant from the supply and return ports on the engine block. No more coolant running through the coolers and no exhaust. They are pretty much deleted in place.

#2 Would be using the blocker plates still and removing the coolant lines and capping at the coolers (green dots on diagram). Instead of re-routing the coolant I would use the plugs that come with the EGR delete kits and just plug the supply and return ports in the engine.

Do these ideas make sense or are there problems that anyone sees with them? Most people will look at this and say why don't you just get rid of the damn things, trust me, I'd love to do that but emission testing will prevent that...

Just an idea I have. Here's the diagram of my thoughts:
