egr delete help needed

[grassmaster]

I finally got around to installing my Dicad EGR delete kit over the last couple days. Overall the kit is good. The two main problems that I am having are the coolant bypass line, even when held in by the machined piece is still very loose, im worried about it leaking. The bigger problem is, I still have an exhaust leak, I have checked all the connections at least 5 times now, and still have the same hissing sound, still builds ok boost, any idea's? Im running out of idea's and patience......

is the hissing constant or does it come and go. the turbo vanes opening and closing will make a hissing sound for a minute or so then quit. you can put your hand over the turbo/exhaust connection and feel the leak. The up pipe/turbo conn is the worst one, I've had h3ll stopping mine from leaking but it has never made a sound. I dont think the coolant pipe is supposed to be rigid, it is sealed with an o-ring and the block off plate under the intake just has two ears to hold the coolant pipe from falling out of the bottom of the intake.

When I first start the truck it sounds normal, then a couple seconds after it starts, the hissing starts. I am familar with the vanes sweeping in the turbo, and i know its not that.

I never heard the turbo hissing before I installed my delete kit, called one of the well known diesel shops and was told that the hissing was normal that I just prob couldnt hear it before because of the egr. Like I said my connection has been leaking and I've nevewr heard it make any noise. Good luck

I installed the same kit a few days ago and took exception to the loose coolant loop pipe. I was not happy how it felt installed, but it has not leaked thankfully.


I am experiencing the exact same exhaust leak too!!! I went back and tightened the up pipe bolts as well as the y pipe marman clamp. I have had a few heat cycles on it and the sound changes pitch once in a while and has even gone away for 10 seconds or so at a stoplight. I did notice a couple of small cracks, 1/2" in length, in the turbo boot. Not sure if that's the problem, but I have riffraff boots ordered. I spoke with justinmix about my issue and he's fairly confident that it's the y pipe flex section. He said I could try to tighten the components up in the order of top of the egg delete pipe first, marman clamp at the turbo, then finally the bottom of the delete pipe.

I have tried to feel the leak and haven't found the exact spot yet. It gets warm pretty quick...

I just did my EGR delete last week and IT IS LEAKING at the intake. It is very loose as stated. It is only dripping 2 drips per min. but that is 2 drips to many!

Anyone else have this problem? What did you do to fix it?

[jimmyv13]

After loosening all of the connections and tightening them again, I was able to feel the leak at the flex on top of the y pipe. Figures.

why the hell anyone would install a 2 piece cooler delete blows my mind. There are high quality, well made one piece kits out there. There is even one kit that uses the factory blue silicone tube (do you know how many of these junk hoses I've seen leak?)

You get what you pay for, truck parts are not an exception!!

i recommend the sinister egr cooler delete kit. i installed mine about 8months ago, and havnt had any problems out of it.

I was able to remove the coolant pipe and replace the o-ring and reinstall it without removing the intake. I already had the Turbo out for other work on it. I fixed the leak. The old o-ring was bad (the one that came with it).
