Keep the stud?

[sprfunk]

Perhaps this is a stupid question, but I have 3 bolts off the mani that hook up to the turbo, and one bolt off the stud. I am wondering how I would get the stud out without taking out the turbo or mani? I guess I am just trying to save time and replace the mani-turbo gasket without taking the mani (rusty bolts are freaking my out for the mani removal) or the turbo out. I am hoping to just be able to slide the into place. Is this a bad way to do it, what would you do?

Some people remove all three bolts and the one nut holding the stud down then push the turbo down a bit until there's enough space to fit a vise-grip on the stud. Then you just clamp the sucker and twist it out little by little until it's off.

That does not sound too bad I am going to give it a try. Thanks, I'll see what happens.

if all you're doing is replacing the mani-turbo gasket you shouldn't have to remove the manifold or the stud. you should be able to drop the turbo far enough to where you can slide a new gasket off. But if your still on the t25 with the hard oil lines it might be difficult. In my experience, removing the stud while it is still in the car is difficult, i couldn't do it.

I was not able to get it out, and the stock oil line is holding my turbo in place very very well... and I cant get gasket to move much at all. I guess I am going have to remove the mani in the morning and get another gasket for the top of the mani, I was hoping to not have to do that but o well. We'll see what happens. WTF

I threaded a large nut on the stud, drilled a hole through it and the stud, and placed a small metal rod through them. Now it turns out with an open ended wrench, like the other bolts.

I think I separated the mani and turbo a bit and tried grabbing the stud between the two with vice grips...but I think that didn't work, so I just locked onto the threaded part of the stud and mashed the threads down and took it off that way. Regardless, I was able to drop the turbo and not the mani. I just had to take the rad fan off to make enough room.

Disconnect the oil line to give more room. I did it the hard way and disconnected the oil line from the turbo. It's supposedly much easier to disconnect it farther down the line where two lines mate. And it's a major pain to tighten the banjo bolt on the turbo oil line if it leaks when you get things back together, so I'd definitely *not* do it the way I did.

But if you can get the stud out (and have 4 new bolts), then you should be able to check the sealing ring and gasket without dropping the whole turbo. Don't forget anti-seize on the threads of the new bolts before you reinstall. And I'd heat cycle the engine and retorque the turbo/mani bolts afterward.

Alright, I just vice griped the hell out of it and got the sucker out... but the gasket would not move. So I bit the bullet and took out all the Mani nuts, expecting to just take it off, but it is still attached to the turbo somehow. The gasket will move all around but it is not coming off.WTF I've never had the turbo off so this is new to me but it looks like there is a male female connection from the turbo to the mani (I am going to look stupid if that is normal), or perhaps its the gasket that has this sleeve (although my new gasket does not have a sleeve). So any time I move the mani the turbo moves with it, and I cant just pull the many up because of the studs going from the block to the many. So I am debating if I should just drain the oil, and the coolant, then unhook the turbo, or try to take out all of the studs that hold the mani in place...

Theres a little piece of "pipe" in there that sort of keeps the turbo and manifold connection "sleeved". That's probably whats in your way. If I recall correctly it is about 1" tall and the width of the turbo "throat"...about 3"?

 

[sprfunk]

Ok, I didn't see that in the Chilton guide picks. So should I remove the turbo or the head-mani studs?

Can't you separate the turbo/mani enough to pull that sleeve out? If the rad fan is in the way, take it off; it's 4 bolts and 1 plug. If the oil line is restricting how much you can drop it, disconnect it (not at the turbo)...I'm not sure if you'd have to drain the oil or not. If the oil drain tube (from bottom of turbo to oil pan) is limiting things, I'd drain the oil and unbolt the drain tube from the pan. There is a gasket for this, though. And the gaskets for the pan end vs. the turbo end are different (I got a gasket set somewhere that gave me two that were the same, and I had to use an Xacto knife to mod one of them to fit).
