Turbo replacement on the JX

Hi.

The next one in line is the next turbocharger .

I had to take my (1Z) outside because the exhaust manifold gasket was leaking – so I removed the entire exhaust manifold/turbocharger assembly and left it disassembled.

Now, the turbo needs to be replaced on the JX (T3 TD).

- Should I remove the intake manifold including the turbo and disassemble it on the workbench?
Can I reuse the (very expensive) screws that connect the turbocharger to the exhaust manifold?
- Can I use a regular socket wrench on these screws, or is specialized tooling required? (Background: I once read that a regular socket might fit.)

Is there anything I can do to prepare the turbocharger before installation that wouldn't be possible after it's installed? (Filling it with oil for lubrication is obvious).

"Thank you."

Hello,
I would definitely replace those screws because they are subjected to extreme thermal stress.
However, no special tools are actually required; the screws have a 12-point head, so you can loosen them with a regular open-end wrench. To tighten them, you will need a corresponding socket. This is available from well-stocked hardware stores or possibly also from spare parts dealers (like ATU, etc.).

Should I leave the crimp attached to the top?

Thank you.

I tried it on a Golf with the AAZ engine code.
Result: The 'Lieber Krümmer raus' product definitely has room for improvement, especially regarding the way it attaches with the Dremo system.
It probably won't be any better in a van either.
By the way, the 12-sided nut costs about 5-6 euros; that's at least what I paid for it.

You should be able to access it easily from below. You might consider reversing the 'T' and using two ramps to increase ground clearance slightly. With an extension and a swivel adapter, along with the multi-spline socket described earlier. We left the exhaust manifold connected. We've replaced it several times before, reusing the screws. It hasn't been a problem so far.

Okay, the turbo has been replaced.

Yesterday we were at a rental workshop (new, well-equipped, with a stage and people who can help if needed), and everything ran smoothly in 255 minutes.

The old turbo is completely broken; the exhaust housing has detached from the rest of it and is rattling around, but the shaft doesn't have any play.

Everything is put back together nicely with the copper paste, and the bus runs noticeably better – even though the old turbo still provided 0.5 bar of boost.

We reused the 12 x 12Knat screws, but had to replace one because my colleague tried to tighten it with a 13mm wrench, which damaged the head. However, everything could still be screwed in properly. I tightened them to the specified torque of 35 Nm, as indicated in the 1Z manual.
