Bumping the thread again.
Couldn't get the screw out yet.
The screw head is almost done for.
Tried to use a screw extractor on a cordless drill. But there is no way I can get the drill to go in straight. Even after removing the plastic partition between the engine and the brake booster, angle is still less than optimum to get any kind of pressure.
Is my option limited to removing the intake manifold itself and somehow try to remove that screw?
