TGP Guru's NEED Assistance!!

[Gearhead43]

I need advice on:

1. Removing the 13 mm bolt under the Rear Exhaust header holding the rear of the turbo to the header. ( I've removed 4 )

2. Do I need to detach the crossover from the exhuat mainfolds to be able to remove the turbo unit from the crossover?

3. Any ideas how to disconnect the oil feed line (Still rounding off even with a flarenut wrench and backup wrench.)

1. If that's the pesky bolt on the underside of the downpipe, I used a 1/4" drive ratchet and a 13MM socket. The ratchet was small enough to fit in there, and slowly removed the bolt.

2. No

3. I left it on there, and disconnected it at the braided hose down by the coils. When time came to remove the turbo, it just lifted right out of there. It's much easier then trying to fit a wrench in between the 2 housings to remove it. I did the same with the coolant return hose down there too, but be ready for a fountain of coolant when you pull that hose off.

Yeah, that bolt on the bottom of the downpipe sucks when it's a HHCS(hex head cap screw)!!!  What I did was replace all of the downpipe bolts with stainless SHCS(socket head cap screw) as then you can use an allen wrench socket and they are much easier to get at.  You may as well retap the holes in the turbine housing as well as it makes it a lot easier to put back together. 8)

Whenever I've taken my turbo out, I would undo the two fittings on top(one was the oil feed and the other was coolant feed I believe).  I would then undo the hoses on the oil and coolant return lines.  A 3/8" socket extension makes a very good plug for the coolant line.   :D

That's the location where I'm trying to disconnect that POS..LOL It will not give  :evil:  :?

I have disconnected all turbo lines expect for the oil feed. Coolant and oil has been drained from the engine since other parts such as the coolant crosspipe and the engine /compressor/dogbone mount bracket have been removed for powdercoating. So almost all fluids have been drained out.

Well Dave sounds like you are in a bit of  a bind.

1.Remove the heat shield under the Pm, 2 screws and yank it out. Yea it will go back in.) Unbolt the turbo from the xover which will allow you to raise the turbo over 2 inches to gain access to that pesky bolt. You wil still need 1/4 tools and something to hold the turbo up.

hey dave, i didnt c where u had posted that u got the bolt out....when i had to replace my x over i had trouble with one of the lower bolts on my turbo..downpipe...................i pried and pried with a 13mm box wrench...........to no avail............so i finally resorted to lifting out the CC unit and using a 3/8 drive ratchet with the flexible handle and a deepwell socket ......it had to be a deep well to get the head of the rachet wrench past the turbine housing...................within a few seconds i had the bolt out....................you could always spray it with wd40 to get it loose.........i used trizol...........which is just an industrial version of WD         but hey if ya already got it out ...congrats.....and if ya didnt ....i hope that helped :lol:

Jud,

I don't have ABS... Remember this is a swap into a non TGP GP...

John,

I haven't had the time to work on it. I have to go buy a 13mm 1/4 drive socket  has my old trusty one busted :oops: I too realize I might need to disconnect the CC and it would give me a bit more room for the racket handle on the rear downpipe bolt.


Thanks for all the help and pointers guys!!

[LukeZ34]

Yea, forgot to mention that in my post... Pulling the CC unit (and it's bracket) out of there gives your arms more room.

a 1/4 inch drive socket?    isnt that kinda small for that bolt?     mine was torqued pretty tight..........i used the 3/8..........and i used a wrench for it that had a bendable handle.........

[sleeperred90tgp]

Pulling the CC is kind of a given. If your sockets are tough, Cut a 13mm wrench off. I have one and it works great with a 3# hammer handle and a sharp blow. You gotta hold the wrench on from the other side.  

Didn't know it was a transplant. I guess I don't read enough or my memory is going south. Most likley the latter. Don't know wheather your lucky or not the TGP is a bitch.

I know. It's a much meaner bitch than the 3.1 N/A will EVER be...

Mine was torqued pretty well too, but the 1/4 worked just fine.

UPDATE:

Removed the CC and I finally got the bolts out.. Thanks guys! I managed to get the crossover bolts off without removing the crossover. I was than able to break the toruqe on that stupid bolt at the rear /downpipe. Now all there is left to do is to disconnect the oil FEED line at the connection where the braided hose meets the metal hose.  I've tried but it's not bugling one bit. Grrrrr


It's on dammmed tight!!!!  :evil:  :evil:  :evil:  :evil:  :shock:

Once the turbo is off It's going out for replacement.

Then I'll do the Dist O-ring seal while I've got the TB off the intake.

Also awaiting newly powdercoated parts from GPXSS

[Gearhead43]

It's off!!! Finally broke the torque on the oil line fitting with a little help from PB Blaster... Great stuff!
