Remove the manifold and use vice grips to grad the affected studs . Apply plenty of grip on the stud and screw out . Replace with good studs using a stud installer or double lock 2 nuts on the stud to enable you to screw it in.

SOURCE: exhaust manifold leak due to broken bolts, how do

If it's broken off below the surface you'll have to drill the remainder of the bolt out. If it's broken off above the surface and you're somewhat handy you can weld a nut on the end of the broken stud and remove with a socket wrench. Here's an excellent read on the how to of removing broken studs....it saves me the time of having to type it all out. Good luck.

I need to remove the exhaust manifold on the right side of a 94 4.9l engine in a cadillac deville. It has a broken bolt in the exhaust. What is involved in removing the manifold?


I suggest you use all new exhaust manifold hardware and torque new bolts to 20 Ft Lbs.
4.5L and 4.9L Engines
RIGHT
Disconnect the negative battery cable. Remove the air cleaner. Remove the exhaust crossover pipe. Disconnect the oxygen and coolant temperature sensors. Remove the catalytic converter-to-AIR pipe clip bolt. Remove the upper manifold-to-cylinder head bolts. Raise and safely support the vehicle. Disconnect the converter air pipe bracket from the stud and remove the converter-to-manifold exhaust pipe. Support the engine cradle with screw jacks and remove the rear cradle bolts. Loosen the front cradle bolts and slightly lower the Engine cradle. Remove the remaining exhaust manifold-to-cylinder head bolts, the AIR pipe, and the manifold. Clean the gasket mounting surfaces.
To install:
Install the exhaust manifold and replace the AIR pipe. Tighten the manifold mounting bolts to 16-18 ft. lbs. (21-24 Nm). Install the manifold-to-converter exhaust pipe and replace the converter air pipe bracket to the stud. Raise the Engine cradle and install the rear cradle bolts. Tighten to 75 ft. lbs. (102 Nm). Lower the vehicle. Replace the upper manifold-to-cylinder head bolts. Replace the converter air pipe to AIR pipe clip bolt. Connect the coolant temperature and oxygen sensor connectors. Replace the exhaust crossover pipe. Replace the air cleaner and connect the negative battery cable. Start the Engine and check for leaks.

Stripped threads in engine block for exhaust manifold


You need a heli-coil kit. Your local parts store should be able to help you find the proper size if you take the bolt with you. Follow the directions carefully and buy a new bolt for the manifold.

1994 V6/AT Isuzu Trooper- Exhaust Manifold Bolt Studs stripped at muffler pipe connection. Can they be replaced without removing the passengers side manifold? What is best manual to cover this? Bob in...


there are several stud removers on the market and several broken bolt removers as well.
The best ones are the ones that have a reversed spiral inside them and tighten down on the stripped or broken bolt / stud as they are turned to remove it.
The Sears unit I use are about 1 inch tall and can be used with a wrench or socket.
Set over the bolt / stud , tap lightly as you slowly turn the tool with a small hammer to start it on the bolt, as soon as it catches switch to a wrench and remove as you would a regular bolt.

Instructions on replacement of Exhaust Manifold gaskets for 1981 Corvette


Simple remove heat shields, removed four bolts on each set(therefore there are 8bolts total) remove exhaust manifold clean manifold replace with new gaskets. If bolts are rusted spray them with any lubricant the night before the job use a new socket and have a sandwhich and a cold beverage handy. Enjoy this its easy and fun. Don't sweat it if you break a bolt in the manifold... just let me know and I'll walk you threw it. .. By the way its a good time to use some dressing on the manifold pipes. It will make the engine seen new.

Bolts to manifold & exhaust rusted


Bolts are screwed into the manifold (actually studs)
Best thing to do is to have someone heat them with a torch and get the nuts free. If the studs are in really bad shape, you will have to remove them from manifold and replace them (usually a torch job as well) Not a job for a burns o matic...need a real torch for this one! Or, just snap them off and remove manifolds to fix them.
