Good news and bad news for my truck

[newbie78]

Still trying to track down my issues causing my higher fuel trim #s, missing at idle etc.. I have no codes.

I decided to check to see if I have exhaust leaks and I found 2 at the Y pipe connections to the exhaust manifolds. Did the old trick with the shop vac blowing air into the exhaust and spraying soapy water on the joints. The bank 1 side exhaust was a major leak as you can see in the pic. The other side was leaking too but nowhere near as bad but definitly saw lots of bubbles.

So I got the left side on and done no leaks but the right side I snapped 2 studs I checked to see if it leaked at idle and I'm suprised with only one bolt on it does not leak. I hacked it up and put a small c clamp on temporarily until I figure out what to do.

See pics. Any idea how I can get these out? I don't have air tools. I have lots of drill bits and a cordless drill maybe I can drill it out? Then I can just put a bolt and nut through it.

Break free. A torch and a vise grip is the only way I know how. Have a bottle of water handy if you try this route

I think I'm going to try to drill them out. They are only threaded into the manifold like a 1/4" so I will just drill down a 1/4" and the rest of the stud will drop out or easily snap off.

Then I can just use a nut and bolt and not worry about the threads on the manifold.

What is that??

A fancy extractor tool.

Get yourself some shorty headers and bolt them in.
