oil return hose bolts broke

[JeviP]

***resolved***So my oil return hose broke. The one that connects right to the turbo going to the oil pan. I was trying to tighten both of the bolts going to the turbo but then the bolts snapped. I cant get s drill to drill it out cause of the limited space. Is it possible to just remove the turbine housing itself and not the whole thing. Cause from what it looks like, the return hose is only connected to the turbine housing. Not the housing under the exhaust manifold. Please someone help.

just got done dealing with this very same problem , that oil hardline can be a nightmare. anyways, it sounds like you broke the bolts on the turbo side? is that actually both bolts or just 1? there are quite a few ways to remove & repair damaged threads from broken bolts. You can buy a helicoil for around $30 or so or pay a machine shop twice that to have them do it.

if the threads are too worn out, you'll basically have to find another turbo to get a new center housing piece , the core of the turbo with all the threaded spots for oil & water. just had to replace my center piece, since I messed up the helicoil.

the hardline has the smallest amount of flexibility but all in all it's stil a perfect length hardlune. which means if you bolt on one side first, that it'll be much harder to get the other side tight and perfectly flat with full tension on the other side. best just to cut the line in half (off the car) and file the.edges , bolt both pieces on separately and put a flexible piece of hose between. maybe cut an inch or so off of lenth to allow more room for the hose, with some sealent for the hose too.

the pans.easier to fix since you can tap the next.size up and add nuts to the inside of the oil pan with some threadlocker. just make sure you're cautious about the metal shavings whenever you tap anything.

Is there a way to just remove the housing where it connects to rather than just removing the whole turbo

 

[1Gina2G]

you're going to have to take the turbo out regardless really unless you have a.small self tapping drill, but honestly you're not going to want to work on it in the car.

to change out the center housing, you're basically doing a turbo rebuild, on top of replacing the piece, saying that's what you end up doing. there's a YouTube video on disassembling / reassembling turbos.

take the turbo off, see if the machine shop can fix it first. The center housing basically IS the turbo itself, to get to it you'll need to remove the turbine housing and the compressor housing.

I just want to remove the housing so I could drill the broken bolts out

Remove the intake, oil feed and coolant lines. Take the clamp off the center housing, and tap the compressor to break the chra loose from the exaust housing.

The part of the turbo that has the broken bolts can't be removed from the car separate from the rest of the turbo, like stated before it essentially is the turbo with covers on either side. Just remove the turbo, it's not that hard.

Yes, you can remove just the housing and leave the hot side bolted on.

Just fallow 1996dsm instructions, remove water lines, oil feed line return line including the V band clamp and you are set, don't forget to remove your air intake.

I think it will be a pain to just remove the chra. Removing the whole setup will only take a few hours. Its really a lot easier then it may seem. There are plenty of write ups on it as well.

 

[1Gina2G]

a few hours ? it only takes 15 mins to have the Turbo completely out of the car. I don't see the reasoning of just taking off the housing, sure it's only what you need to get to, but you're only cutting out the part of removing the exhaust manifold bolts, easiest to get to.

think about putting the Turbo back together, ALOT easier to put the housing lined up out of the car on the floor now wouldn't it?

I agree, if you leave the turbine housing bolted to the car and just remove the center section from the turbine than it will go a LOT faster. You shouldn't even need to drill the bolts. You should be able to take a small flat head screw driver and just turn them out.

i think you misread my post.

i think you misread my post.

I accidentally quoted the wrong post. I meant to quote miguelmcv

okay well you being a wiseman, why wouldn't you agree with my post? how would it be any easier to just skip the 4 manifold bolts, if your going to have a harder time when it cones to reinstallation? doesn't make any since to me why you wouldn't just take the whole thing off.

 

[Bud92gsx]

Well, here is the center with the bolts in.

You must be logged in to view this image or video.

.You need to get your snapped ones out.

Its very simple to get the center out.Your problem will be the broken bolts tho.Do you have time to wait..Umm I'm sure there is a guy who would take your bolts out for You.

I pretty much meant the whole process would take a few hours. Point is it makes way more sense to just pull the turbo and fix it.

It's not that easy, the way you say it is, But not really.

There are 4 bolt from the manifold to the turbo hot side, there are 2 more from the O2 housing to the Down pipe, and that's with out talking about the gaskets, which we all know when removing them, they mostly have to be replaced, (I am not saying he shouldn't replace them), But the more important on this (that I think why the OP doesn't want to take it off) is the risk of breaking the manifold to turbo bolts, which we all know they are a big headache to get them out,.. We prefer to take the bolts out (all of us that have being working on our cars and know the process if they break) and at the time they being out, to put some anti seize on them.

To the OP,

If you are confident on taking the hot side off, go on and you can replace the gaskets and add some anti size on the bolts, But if you think that is not your best time to deal with another broken bolts, then taking only that part will save you some headaches, However, most of the bolts can get out with a good technique.

Ok so I think I'm going to take the whole turbo out. Which gasket do I have to replace for sure.. the gasket from manifold to turbo? Would not replacing this cause boost leak? I just recently replaced my exhaust manifold. Replaced the gasket going to the head. But not the gasket towards turbo. Now car doesn't run past 20km/h. Could this be cause of my disconnected/completely broken off oil return hose or cause I didn't replace the gasket towards my turbo. I'll fix this broken bolts first

Hey guys so I finally got to removing my turbo. I actually removed the whole thing including the manifold. It didn't take long at all. Drilled the broken bolts out. Today I will be putting everything back in. Would I need to adjust my biss screw if I replaced my manifold with an evo III manifold and 2g maf?

 

[Spoolin92GSX]

You shouldn't, but you'll need something to tune with to compensate for the 2G MAF. If not you will run dangerously lean.
