83 240 Turbo Exhaust leak

[vcolper]

I have an exhaust leak at the down pipe where it connects to the turbo exhaust. I see theres no gasket there.
Its all stock
How do I fix this?

Thanks in advance

Is it leaking from the connection between the cat and the first pipe? #5 is a metal donut that seals the connection. It may be missing or broken.

Further up... where the down pipe connects to the output of the turbo... before cat

It's usually loose or missing nuts or broken studs if it's leaking at the turbo.

It's supposed to use special studs and nuts because of the extreme heat and they're not cheap.

All nuts and studs are there. I just finished removing them...they were tight and tough to remove. Ill clean it all up and reinstall to see if it seals better.
Thanks

Be sure to tighten the nuts evenly or you'll cock the pipe and it won't seal properly.

I just realized that one stud broke off during me removing it. Ill guess Ill be tearing more apart to remove the broken stud.

Thanks

The wastegate is held to the turbo with five bolts or studs. Soak them down very well with penetrant. Let soak for a good long time. Once you have the wastegate off you can fix the downpipe studs easier. Be sure to disconnect the wastegate actuator from the wastegate.

Taken care of.
