Good evening folks. Please don't flame me for this as this is my first post. I recently bought an 07 LE CC 4x4 and both manifolds are cracked. I bought some headers and set out to knock it out today. I managed to get the passenger side swapped out by taking the studs out because I can't get the 4 bolts for the MM out. What's the trick? I lifted up on the motor at various pressures and tried to break them with an impact with no joy. I also couldn't get to the two front ones on each side because how the heck! I thought they were only torqued to 65ft/lb. I have searched and searched but every post I found, the photobucket link for pictures was broken. So please..... can anyone give me the guidance I need? Thank you all!

If they're that tight you're just not finding the right height that the motor needs to be raised to. It doesn't take a lot to get the pressure off the bolts, then once you have them backed out most of the way you can raise the motor a little more to get some room.

Use a piece of 2x6 between your jack and the oil pan. Remember to only loosen one side at a time. You want to tilt the engine, not lift it straight up.

I pulled the manifold studs out instead of doing the motor mount and lifting the engine. It wasn't bad at all.

That's what I'm doing now. I have one stud that I rounded the spline off and have to vice grip it out. I will be replacing that. But, since I work nights and will be working Saturday-Monday, I'll have to start back up on Tuesday.
I don't feel that is a dumb question but yes. I'm having to use multiple extensions to reach then MM bolts. Pulling the studs is not what I wanted to do but oh well.

Hope it goes well. Keep us posted. I think my installation took like a week or so.
