Up Pipe removal - Diesel Forum

freestroker · 11-02-2008, 11:20 AM

I need to replace my up pipes. Can the up pipes be replaced by simply removing the bolts at the manafolds and lifting the pipes out through the engine compartment, or do I need to remove the inlet to the turbo charger and remove each pipe separately?

Thanks

TTT. Someone has to know this. It would be great if I can remove the pipes as one piece. The bolts on the Y fitting at the Turbo look to be a real pain to remove (access). I think that removing the manifold bots first would make removing the bolts at the Y extra difficult. Any help here?

Thanks
Peter

To replace the up-pipes or the gaskets you need to remove the bolts on each manifold, and if the gaskets are bad, the pipe will fall out of the collector behind the turbo. You also need to remove each of the 4 bolts at that collector, and drop the flange and gasket. You probably will be able to just replace the gaskets, use the F-1750 from Car Quest auto parts, it is the OLD GM gasket, very soft and will mash out to seal, the newer part numbers wont seal that well. (If your pipes have bad "Dents" in them where the gaskets go, replacement may be necessary) Stock ones should last a good while, some like to spend nearly 400 dollars on the "Bellows" pipes..... to each their own.

I just put in the bellowed up pipes since I had my trans out for repair. If you plan on replacing the whole pipe I would recommend removing the trans. It was a pain even with the trans out, not alot of room in there. Also, I cant see the pipes being able to be removed from the top.

i just finished this yesterday. the absolute easiest way to replace these are to take out your turbo and take out the up pipe to manifold bolts and pull them right out the top just like you want to do. they might even fall apart while doing this and make it easier for you. i would suggest the SS one piece up pipe from DI. they are one piece and bellowed and are wonderful. then you can just drop the new ones down from the top start your bolts on the bottom and then put your turbo back in and then tighten the manifold bolts. get new bolts from lowes or somewhere as the stock ones will be toast. the v-clamp on the back of the turbo to the up pipes will be a son of a to get off. just make sure when you put the new ones on you hook them up to the turbo before tightening the manifold bolts so you will have plenty of play to get it on there. pm me if you need any help if you want ill give you my number so you can call me if you like. good luck....

I stand corrected. Doing this from the bottom there did not look like there was any way those pipes would make it out the top.

Thanks guys. Bill I did order the DI unit and the turbo is already out. I will follow your suggestions. Sounds easy enough.

Although it can be done without removing EITHER one, I think I would remove the turbo, LONG before I would pull the transmission for replacement of these!
