  • Removing Heads on 3400-How to hold engine from Rotating?

    I have a 2001 Monte Carlo with the 3400 V-6. I have a blown head gasket as well as the normal leaking LIM gaskets. I need to remove the 2 engine supports (Dog Bones) to get the heads off. But the engine wants to rotate back against the firewall. How do you hold the engine in the upright postion to bolt the back head on?
    .
    Thanks for all the help. I am also using the new and improved LIM gaskets so I hope this will be a one time only repair!!!

    haha i had this problem at the junk yard when i removed some heads the engine would rock, i just had a buddy sit on the windshield and push with his legs so it didn't rock or use a big pry bar
