Fixing exhaust lead
 

The rearmost stud is broken on my 2.5 4cyl (95 YJ) and it has an
exhaust leak. It was this way when I bought it so I have no idea how
long it has gone like this. Yesterday I took it to a mechanic and he
said that he could just remove the manifolds and broken stud and put
in a new gasket but that there is only a 50% chance it will seal
properly. He said the sure fix is to mill the exhaust manifold and
mating surface on the head, stating that the exhaust leak could have
erroded the mating surfaces.

Does this sound reasonable?

Also, would the intake manifold also have to be milled to keep it at
the same thickness? I worry about this because some of the fasterners
are used to hold both manifolds in place.

Thanks

Any advice would be appreciated. I´m sure some of you have dealt with
this before. Thanks

Depends on how much damage has occurred. It might be minimal
or something that can be taken up with one of the better ringseal
type gaskets and some permatex copper. milling the head and
exhaust manifold is much more expensive than re-doing the gasket
so I'd probably try the gasket first. Then if it was necissary
I'd get an aftermarket set of headers for it and have the block
checked. Checking the block for erosion isn't too difficult
just time consuming.

This is an issue. Minor differences should be taken up by the cone washers
but yes, if they mill too much. That's why I suggest looking at a nice
set of headers.

er.. head checked.. like I need mine checked for calling the
head a block. guess I'm a block head.

Thanks to all who replied. This mechanic is highly recommended by the
local jeepers so I would tend to trust him. I was starting to doubt
since milling seemed extreme to me. However, based on your comments
it seems he was just letting me know the worst case scenario. I'm
thinking if it needs milling, I would rather get headers or a new
manifold and mill only on the head to avoid mismatching the intake and
exhaust manifold thicknesses.

Thanks

I have seen manifolds erode or pit very badly if a leak is left unfixed
for a long enough time, so yes it is possible. If you trust your
mechanic, then take his advice. There are many good mechanics out there,
and there are also a lot of shady ones.

There is a gasket glue designed for exhaust gaskets in case of pits from
a leak and it is not unheard of to double the gaskets if it has a slight
warp.

There is a gasket glue designed for exhaust gaskets in case of pits from
a leak and it is not unheard of to double the gaskets if it has a slight
warp.

Re: Fixing exhaust lead
 

Actually, milling is really just plopping the head and/or manifold(s)
down on a big blanchard grinder. It's a 24" diameter horizontal grinding
wheel, just slide the part over it. Takes just a couple minutes to
flatten things out. 99% of the time is getting the head off. Might as
well think about grinding the valves while it is off.

Thanks to all who replied. This mechanic is highly recommended by the
local jeepers so I would tend to trust him. I was starting to doubt
since milling seemed extreme to me. However, based on your comments
it seems he was just letting me know the worst case scenario. I'm
thinking if it needs milling, I would rather get headers or a new
manifold and mill only on the head to avoid mismatching the intake and
exhaust manifold thicknesses.

Thanks

Thanks to all who replied. This mechanic is highly recommended by the
local jeepers so I would tend to trust him. I was starting to doubt
since milling seemed extreme to me. However, based on your comments
it seems he was just letting me know the worst case scenario. I'm
thinking if it needs milling, I would rather get headers or a new
manifold and mill only on the head to avoid mismatching the intake and

Thanks for the link. I am also seeing some 2.5 exhaust manifolds on
