Up-pipe

Hey guys, Got my truck in pieces. Doing the CCV reroute and Taking care of the whole EGR cooler Ect... I've loosened the clamp for cooler exhaust
inlet. The clamp seems to be on there pretty tight with the clamp loosened off. I haven't loosen the pipe/manifold bolts and the upper 2 bolts. These have Flex joints will they spring a little when I pull the bolts out? Should be able to loosen that clamp by wiggling the up-pipe after the bolts are out? Did the pipe line up ok when re-installing? Did you have to pull the turbo to get the manifold/EGR cooler out or will it slide past? Should I just weld a frost plug in the up-pipe and leave the cooler alone
seeing as it won't see the heat it did before?

Thanks for your input. If you have any hints send them my way.
I will be back at it a little later.

I'm not really sure as I've never done egr block. I have read that once the pipe is blocked the cooler does not have any more problems. Also the flex pipe shouldn't have any spring in it making the re-install fairly simple. Good luck and hope someone more informed will chime in, there are alot of really smart guys on this board.

Thanks for a reply Tex. I'm going to carry on. Maybe I'll get more replies.

Yep. Should come right out. Good penetrating oil like Kroil makes the exhaust bolts easy-peasy.

No problems whatsoever. None. I have the Liberator kit FWIW.

Take it out. Of all the things you're doing, removing the turbo is pretty low on the difficulty scale.

If you're going to replace the exhaust up-pipe, chunk the EGR cooler altogether. Leaving that disaster in place with coolant flowing through it is begging for trouble.

When removing the intake manifold, there is one thing that tripped me up. There is a fuel line connected to the manifold just under and to the passenger side of the intake elbow - and I didn't see it at first. Otherwise it's a pretty straight-forward procedure.

The only thing that was a bit of a bear was the exhaust manifold/up-pipe connection on the driver's side. I took the whole Y-pipe out so I disconnected it at that juncture - and that is a tight spot. On the bright side, I discovered that very joint was loose, so I managed to find my elusive exhaust leak by default.

I want to keep the cooler there for looks. I will weld both exhaust in/out
closed in case the coolant side of the cooler cracks it will fill the exhaust side and act like a coffin. Did you leave the fuel / oil filter housing attached to the intake, fuel lines. What is the procedure for removing air from fuel lines? Key to run 3 times for 15 seconds each time?

You disconnected the Y-pipe at the back of the turbo, pulled the up-pipe from there and take it apart on the bench.

Did you get an oily mess from the line on the turbo when you removed it?

Thanks for your time.

Gotcha.

Nope. Took it all apart.

Exactly. Once disconnected from the turbo and turbo removed, I disconnected it from each exhaust header and lifted the whole Y-pipe out. Probably not entirely necessary, but fiddling with the up-pipe to Y-pipe connection at the back of the engine bay wasn't high on my desire list. EDIT - Having to do it over again, not sure I'd remove the Y-pipe again. When I mentioned the exhaust header to up-pipe connection on the driver's side was a bear, that was the highest difficulty piece in the whole puzzle. Very little room to work, especially if you're, um, not that small...

Nope. Remove the bolt at the line to the manifold, and lift it straight up off the connection underneath. Pretty undramatic.

Hey Black1, I'm going to pull the turbo. Did a search but can't seem to find anything.
The base of the turbo has little feet with 2 bolts in each 3 or 4 feet. Are these the
ones? Where is the oil return? I believe the oil in is on top.

Thanks for your help. Going to the steeler to get some gaskets
