Reply To: SOLVED – 1957 RDE-19 35hp. Belly pan / exhaust cover.

One should always use a tap to chase those threads to ensure they are as clean as can be. Also note, being that those screws are not very big, your impact driver may not do what you hope, penetrating oil would be your friend and some heat to get it to soak in there.. Patience cannot be overstated here..

The challenge is the screw head kind of seal the top so getting solvent in there is a challenge. If the head breaks off, try to remove al lthe others, any that break, THAT is when the solvent can work its way down the broken screw to get into the block…Again, patience…
