Turbo - Down Pipe Clamp Won't Come Off

Hey Guys,

In the process of takin out my turbo to replace the STC fitting on the HPOP, was wondering what I should do other than loosen the clamp that holds the down pipe to the turbo. They just won't separate. I have the 3 turbo mount bolts off, the oil tube off, the manifold to y-pipe (both sides) clamps off, and the turbo still won't budge. I loosened the down pipe to turbo clamp and the y-pipe to turbo clamp both all the way, and the thing won't budge, even with me sitting on top and shaking with all my 200 pounds, nor from the bottom yanking on the down pipe. I tried WD-40 too, worked on the turbo bolts, but not on these pipes. Am I missing something to these clamps? The service manual calls them "Marmon Clamps" if that helps.

Thanks

It sounds like the clamp is not opened up enough. Also don't just loosen it make sure the clamp is off, not all the way off let it hang there for ease of reinstallation but the clamp should be able to spin around. You may have to give it a little smack with a punch or something to get it loose they can become quite attached.

Yea, I got it off after posting this. I took a screwdriver and just pried under the clamp a little, and bam, it snapped off. It was just seated, and needed a little help coming undone. I got the turbo out shortly after that, just took a lot of rocking back and forth, but I can see how this would definitely be easier the second time. Now hopefully it's not that bad putting her back in!

Just use lots of anti-seize. Butter those clamps really well..

Turbo is out, pedestal is out, now I am just trying to get at those 2 bolts in the back under the EGR cooler to get the HPOP cover off. I guess I am going to have to go to the store to get an 8mm crow's foot, because a wrench is just not working.

So I was taking off the Y-pipe and the Up-pipe (still attached), and when I pulled them out, I noticed a good amount of coolant dripping out of the pipe as I was lifting it over the engine. I inspected a bit more, and it looks like it dripped coolant on the floor as well.

Would it be possible for me to break it on the inside without knowing it while I was taking the turbo out? I don't recall hitting it hard or anything in the process. I am guessing that the leak has been there because the tech at the dealer said that he got some white smoke when he started it one time a few weeks ago.

I have been planning on doing an EGR delete, but I wanted to do the EGR induction cleaning first. It looks like I will be doing the EGR delete a bit early. Does anyone know if there is an induction cleaning (Wynns maybe) that doesn't use the EGR system?

I'd say since you've already got most of the stuff off the truck and out of the way, why not just do the EGR delete now?

Your best bet is to just delete the thing entirely from the truck. It doesn't matter if you clean it today, next month the thing will be dirty again. They do nothing but constantly get clogged and blocked.

Last thing I would want is for the blocked up EGR cooler to take out a pricey Oil cooler or head gasket!
