I recently embarked on a project to replace the head gaskets on my 1988 Subaru DL wagon and the two tall bolts on each side of the intake manifold broke when I tried to remove them. Now that I have all the bolt heads off the intake manifold it appears that the remaining bolt shafts have corroded to the extent that the manifold is not moving when I try and lever it off the block. I am afraid to use too much force for fear of breaking it.
Has anyone run into this problem before? Any suggestions? Is not worth the efforts?
Thanks
