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. nrs wrote: > On 15 mar, 17:28, c <c...@me.org> wrote: > >>nrs wrote: >> >>>On 15 mar, 08:59, "nrs" <neale...@yahoo.com> wrote: >>> >>>>The rearmost stud is broken on my 2.5 4cyl (95 YJ) and it has an >>>>exhaust leak.

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.
