When I bought my 1990 LS400 with 40,000 miles on it I didnt find out until later that one of the manifold studs on the top had been snapped in half. I can see half of the stud broken off in the exhaust pipe. Is it very expensive to have someone take it out and fix it? Does anyone know the procedure?

The car is 18 years old - with apparantly no problems. I would leave it alone if it were mine.

I would just leave it but it does sound like it has a exhaust leak coming from there.

$10 says its your notoriously unreliable an utterly inaccessible EGR pipe at the back of the engine block. My 92 has a leaking EGR pipe and sounds like a tractor compared to my 98.

If you can find a welding shop in your area that is familiar with using a welding technic to remove the broken stud. It is possible to build up the broken stud with a welding rod, then weld a nut to the build up portion of the stud, then remove it with a wrench. The heating process of welding will usually free up a frozen/broken stud like you have. Make sure the person that says he can do it CAN really do it. Don’t let some Billy-Bob screw up your cylinder head. This can be done, I have personally done it and so have many other competent welders.
