SCT fitting?

What is it and what ate the gains from doing such a mod? I am fixing to do a egr delete and I see that everyone says to replace it while in that deep but I just need to know what it is. Where do u get one?

It has no performance gains its just a prevenative maintanence thing. Your truck doesn't have one anyway so no need for you to worry. Its the STC fitting(Snap to connect) and it connects the HPOP to the branch tubes on the 05-07s the piece is know to break the o rings inside and leak oil resulting in a no start from not being able to build enough pressure to fire the injectors.

Hey Guys
New guy here. I have an 06 6.0 litre in my shop and I am replacing the STC fitting with the update. Upon closer inspection I noticed the the fitting and tubes bent back from pressure I assume and cracked the rear engine cover (trans. adapter) witch is aluminum
Truck was towed in with a no start and oil leak before it quit. Has this ever been seen before and wondering if it broke the crossover tube witch I will find out once I repair it and pressure test it. Any input would be great. Thanks Kevly

you're going to have to replace the rear cover but as far as the branch tube goes you should be able to just bend it back into place

branch tube replacement requires removing the valve covers and several rockers/injectors on each side

I'm doing the egr delete in a few weeks, should I do the stc fitting upgrade at the same time? I will be replacing the turbo supply line and the drain tube. I ordered the turbo mtg kit also, should I do anything else while I have it apart? Sorry about the hijack. Thanks.

I might do mine when I do my studs

if you don't know if your STC was replaced then it is wise to pull the cover and find out.

It's a ticking time bomb. I've never seen one that didn't have a decent amount of movement in the connection. when it's new there is none
