You could just have some strong oxidization between the two components- like a seatpost stuck in a bike frame. Try soaking the points of contact with PB blaster, Kroil, or other high-quality penetrant and letting it sit overnight. Then, go to town on it. If can find a good fulcrum, could try a lever and/or whacking it with a deadblow hammer.
It will come off.

Here's what is in OP's previous topic:

My van is blowing white smoke (coolant) on start-up until it warms up. I pressured tested the coolant and its leaking out of both head gaskets. The compression test came back 110,120,110, 145 and the leak down 36%, 30%, 8%, 12%.
|
In that case, I guess removing and examining the heads is the way to go indeed. And in this case, removing the engine makes sense.

Gentle prying between AC and mount will move it. No blows or impacts, just pressure

Abscate is probably right. I was going from 0 to 99 with my suggestion. There's a lot of numbers in between those. I guess I was assuming you'd already tried steps like gentle prying.

Don't worry. That happens a lot until you buy experience through more tools to handle the unexpected!
Just take one thing at a time and suddenly there won't be anymore things.

Forgot to add to hit those points with some good penetrant oil ( not WD40) a day before, too.

A/C is off ...penetrating oil and breaker bar did the trick.
Things are moving well but am stuck on how to remove the shields covering the rod tubes on the bottom side of the engine to access the coolant head drain plugs. The bolt I am having difficultly with is the one connected to the exhaust header pipe. It appears to be rusted and seized. I have tried penetrating oil and heat but to no avail. I'm worried about rounding off the head of the bolt with the level of force I am having to apply to the bolt. Any tips, tricks, suggestions!
Thanks In Advance! |

Don't know what your mean by heat, but getting it red hot with an Oxy-Act torch should do the trick. A nice red spot on one side of the nut, a couple of quick cranks of the ratchet, then make a new hot spot again if need be. |

| I heated it with a small butane torch. Will that temp be high enough to do the trick? I didn't leave on long enough to form a cherry spot. I had read that too much heat will weaken the stud. Is that true? |

With enough heat from an Oxy-Act rig you can get a cherry red spot on the nut without getting that much heat into the stud. This really probably can not be done with a butane torch as the heat flow just isn't high enough.
When you do get the nut off use copper plated nuts when you go back together. If you could find brass nuts they would work fine as well. There are definite alloy exhaust nuts for newer rigs that would do great here too, but I can't suggest a source off hand, maybe Mercedes or BMW? |
