rusted bolts are keeping me off the road!

[jackmalone2001]

(94-3.4l v-6 5-speed manual) I have to remove the exhaust crossover pipe to remove the starter motor. (bad starter I think...) The bolts to the exhaust manifold are corroded very badly and I cannot loosen them a bit. ANY ideas on how to remove these?

Penetrating oil (pb blast) although it don't matter, 80% chance on each of those snaping, the only way to achive the 20%, lots of patience.

Not sure if the setup is the same, but I had to replace the starter on my 94 Z. It looked as if I would have to drop the Y-pipe out, but I didn't. If you pull off the tranny cover just behind the y-pipe, that should give you enough clearance to pull the starter out that way instead of messing with rusted bolts. But if I am wrong on the setup, WrightZ28 is correct with the penetrating oil.

WD40 or Kroil. I stand by them as miracle workers. Use a breaker bar and a socket wrench if you can.

will it come out if you take off the trans cover + solenoid of old starter? thats how we did it on my 89 formy

Well, on my friends 4th gen all we did was put a pry bar up on the motor mount and pushed the exhaust down a little, not the best thing to do, but it got the job done.

Thank you to all who responded!

Using patience and plenty of the PB Blaster I was able to remove the cross over pipe and remove the starter (I was right--it was a bad starter) and very quickly replace it.

One note though, after using such a product on your exhaust pipes, expect a prodigious amount of smoke, as it burns off. For a few moments I was very alarmed when smoke came billowing out of my engine bay as the pipes heated up.

Again, guys, thanks for the advice!
