i went to bunnings today and bought Shelleys Industrial Grade Silicon Sealer 401.. Removed the electrical tape from the coil packs and resealed with some silicon.. waited around 4 hours so it dries up nicely n took the beast for a thrashing..
i must say, it does seem more reliable to use the silicon.. when i took my coil packs out today, i did notice the tape had shrunk a bit a little bit over the split..
