Can anyone tell me what type head, (torx etc.) and what size, the screw for the center bolt on the "right" (sitting in driver seat )for the upper intake manifold for a 1988 5.0 is?

I checked the haynes manual and could not find any info except it was a screw.

I have the rest of the bolts out and am in the middle of replacing the valve cover gaskets....please help! I have got to get this thing off and done!

The Engineers did it again. (Hey guys lets put a screw in place of a bolt, and put it in the most difficult spot to reach so you can't see it! That will keep them guessing!)

 

It is an allen wrench head. As far as the size I am not sure

 

T-50 torx and you need a 1/4 in. drive to reach it.

The same question was posted in another forum at almost the same time as mine, and they answered back.

Thanks!
