I was wondering if anyone out there has found a way to safely fill them in?If not is there at least some kind of fix anyone would suggest?If you are not sure what Im asking about its the deep little square pits on top of the prv between the heads.They always get filed with dirt and moisture which could cause them to corrode through.I would like to fill them in with something but dont kow if its such a good idea since this might allow some moisture to be trapped in there,exactly what i dont want! --------------------------------- Do you Yahoo!?
