Turbo Charger Removal

[Nick8564]

I need help with removing the turbo on a OBS motor. What wrench or socket combo has anyone used to get it off. Its a 5/8 nut, but nothing fits in there. Can I pull off the intake side? What size is that bolt, looks like a 12 point something. Any help??? I broke the upper part of the exhaust Y coming off the exhaust header trying to brake the bolt. It was sized pretty good. Should I replace it with the newer clamp style along with the exhaust side of the turbo? Or get a good weld on it?

The OBS turbo is all metric. The 5/8" is a 15mm. The 12 point I think was a 9mm. The collector Y-Pipe is the only Y-Pipe available for the OBS type turbo. It is cast iron and unless you are really good at welding cast you are going to have to buy a new one (I did the same thing removing mine for the first time. On install use Anti-Seize for future removal)

Sorry, I don't have the part number on me.

for the 2 nuts on the bottom of the colector use a regular 15 mm wrench. when i pulled mine on the passanger side put the wrench so it is almost level then i took a 3-4 ft piece of angle iron i had sitting around put it above the wrench and down under the firewall alittle bit and gently push down on it and it should pop free. for the driver side have the wrench angled up alittle put the end of the angle on the back corner of the head not the valve cover and pull up on it. for me the hardest bolt was the passangerside rear pedistal bolt which is 10 mm. and the 12 point bolts for the turbo are 8 mm iirc
