TJ exhaust crack advice
Hi guys,
A few months back I noticed my 98 tj exhaust manifold (6cyl) was cracked at
the weld where the two main pipes join the flange. The top pipe weld has the
crack, its about 1.5" right on the top area. No noise. It hasn't gotten
worse all winter. In your experience, will it get worse? I have 70k miles
and I don't do any serious offroad. I'm looking for an excuse to not do the
job. Should I wait until it gets worse or just go ahead and do it now? My
plan, if I do it, is to get the one from 1A auto that some guys here have
gotten. Any surprises in doing the job? Will the bolts from the engine come
out easily, or should I plan on breaking one? If they come out easily,
should I re-use the bolts or get new ones? Will the old gasket come out
cleanly or will I have to spend some time scraping and cleaning. Dumb
questions, I know, but I find I have a much more enjoyable job when I think
it through first and there are no surprises. Thanks for any tips and
advice. -Nick

Yeah, it will probably get worse. Mine sure did anyway, ended up with
cracks in a couple different places even. I procrastinated until I
couldn't stand the noise anymore, but probably should have replaced it
sooner. As far as installing a new one (I opted for a header instead
though), it was pretty straight forward. Bolts didn't break, and I
re-used them. Old gasket came right off, so no cleaning. Only 'gotcha'
I ran into was that I didn't get the header properly seated over the
little manifold stud pegs the first time. Created one heck of a vacuum
leak, and the engine would rev WAY high when started (like someone was
flooring the gas pedal).

I had the same problem on my 97. I waited until the crack became
hugh. That became a hidden problem. When i put the borla header on,
i got check engine light to come on and had 4 error codes. Dont wait.
change it now before the computer brain starts to adjusting the
fuel/air mixture and other things. Hope this helps you. Got the
codes of in about a week. the computer brain need to learn the new
settings it was getting.

I had the same problem on my 97. I waited until the crack became
hugh. That became a hidden problem. When i put the borla header on,
i got check engine light to come on and had 4 error codes. Dont wait.
change it now before the computer brain starts to adjusting the
fuel/air mixture and other things. Hope this helps you. Got the
codes of in about a week. the computer brain need to learn the new
settings it was getting.
