Help please - Replacing primary on TT BG5

[xsvpwr]

Hey guys,

I'm going to attempt to replace the primary turbo on my vehicle as it seems to be poked so was hoping if anyone has any experience in doing this they could please give me some pointers? Any help would be much appreciated.

Cheers,

Ben

Heres a basic rundown of the removal (stolen from my workshop manual..)

1) Set the vehicle on the lift.

2) Disconnect the ground cable from battery.

3) Remove the intercooler.

4) Remove the center exhaust pipe.

5) Lower the vehicle.

6) Separate the turbocharger joint pipe from turbocharger.

7) Loosen the clamp which secures turbocharger to

air inlet duct.

8 ) Disconnect the engine coolant hose.

9) Remove the bolt which secures bracket of oil

pipe to turbocharger.

10) Remove the oil pipe from turbocharger.

11) Remove the turbocharger bracket.

12) Disconnect the oil and coolant outlet hose from

pipe.

13) Take out the turbocharger from engine compartment

mean, cheers bro. I'm thinking drain the coolant first so I don't get a nice big green puddle on my garage floor?

yep good idea then remove heat shields and follow instructions from jord also there is a prick of a pipe under turbo that runs back into crankcase just has simple clamp on it if turbo doesnt come out thats what will be holding it (thats how i found it) also use tons of wd40 or similar penetrant on exhaust housing bolts before you try to undo just take your time and you be sweet as

cheers mate, yeah I am armed with spray penetrant I am sure those bolts are going to be a mission!

Only thing i'll add to this, if the turbo has failed, change oil/filter before start up. And if need be change oil/filter after a 20min or so run.

The turbo bearings can leave nice little bits of metal in the oil.

dam i wanted to say that

Check the oil flow to the turbo, 9 times out of 10 the banjo filter is blocked causing low oil flow/pressure and was the cause of the first turbo dieing

Would this apply to replacing the Primary in my 02 Legacy? Also roughly how long does this take to do?

[Joker]

pretty much

[xsvpwr]

probably four hours, possibly more if the nuts are as stuck as mine were. A very long socket extension is your friend to access the nuts holding the turbo on to the up pipe, also long needle nose pliers and a decent light to access the clamps on the coolant hoses.

buy new gaskets, you will more than likely damage the original ones when removing down pipe off the back & turbo from up pipe resulting in leaks when you bolt the new turbo up.

Where are you based?

edit: I see Hamilton or I would have offered some help.

Yeah hamilton mate, Thanks for the thought tho!

Yip thats a prick of a pipe and annoying to get back on (hand doesnt twist that many angles at once)
