Question 6.3 Exhaust Manifold Bolts

Greetings all! New member here, help me out. Looking to purchase a 6.3 with broken exhaust manifold bolts on one head, creating what I imagine is a nasty noise. I have not seen the car, except in pictures. Is this a very expensive repair? I know that engine takes up all the room there is under the hood. I don't mind fixing a few things on this car. The asking price seems right and there don't seem to be many other expensive thing to make right. The paint is quite weak, and I know that is expensive to do correctly (another question for another time). This particular problem does have me concerned. All comments and advice welcomed!

Many thanks,

If ANYTHING on the car breaks, it will be BIG $$$$$. If you are at all cost sensitive, rethink it.

If you aren't cost sensitive, the car will be really neat to drive and own.

It depends

If the exhaust manifold bolts are broken, you can fix this your self depending on your mechanical abilities. Basically, the manifolds will have to come off, holes will have to be drilled into the stubs and pull out the stubs. Then buy new bolts and nuts, reassemble and you are done. I had to purchase a 90-degree drill and had my 3 ton floor jack handy. I have a '73 450 SEL that this needed to be done.

I am not sure how much something like this would cost. This is not as big of a problem as it may sound. I love my car and I am willing to fork $5000 for a rebuilt engine. Is it worth time and money to you?

How did they break them is the question you should ask. It may indicate a larger problem ranging from loose exhaust, low suspension or even shifting engine.

Then again, someone may have simply over tightened which is easy to do on heat treated metal.
