Hi Avery,
Did the water reach the pin block area? If so you may some
pin block seperation. I have used epoxy (same brand) in the following
manner with success. Step 1. Slacken off pin block jack. Step 2 Tape
underside of block. Step 3. Apply a liberal amount of epoxy into the
hole with hammer shank and hair drier the epoxy will run like water.
Step 4 retighten jacks and redrive pin. Go for coffee.
You need to work quite quickly as the heating of the epoxy sets it up
a lot faster, but it lowers the viscosity so that it can be squeazed
into any cracks. Having the pin on the coil before you startis
important,I'm sure this will work.
