Has anyone ever had this happen during a header install?

Hi everyone,
I am in the process of installing headers and had something that I've not seen happen.  The instructions said to remove the center bolt from the engine mount to raise the engine up.  I did.  When I started to jack the engine up, the entire car went up!  The mounts just simply refuse to seperate.

You must be missing a bolt somewhere.

because of failed motor mounts, especially with high HP or Tq motors we used to weld together stock motor mounts with a plate steel to create a solid mount. It was crude, but it worked when there was nothing else out there that wouldn't break after a few runs. Look around for something connecting the frame to the motor, I'm betting your missing something.

Support the car on jack stands. Remember, as you attempt to raise the motor, you are unloading the suspension. The body will rise quite a way along with it before it separates, unless it is supported on jacks.

might want to just give it a little extra help with a pry bar

some cars came with torque straps to limit mount streach . If you have one unbolt it.

Agreed, I had to do this as well   Just be careful where you put the bar so you do not bend anything.

Thanks for all the replies guys.  I ended up just disconnecting my centerlink and then putting it back on.  Seemed easier to me.

if your car uses the single long bolt that goes front to rear you have to back the nut way off and then tap bolt out a bit to get the washer past the ear on k frame
