trying to take the egr off of my 08 4.6l to clean it and none of the bolts want to budge.. i just soaked it in wd 40 but what the hell, am i just weak?

 

WD 40 was not designed to be a penetrating oil. Pick up some PB blaster.

Wd-40's main ingrediant is water, its basically meant to be a very temporary lubricant. Really good for drilling through steel and need to keep the bit cool. Pb blaster eats through stuff, put it in a styrofoam cup and wait about 5 minutes.
