I've had a few minor leaks. I'm re-installing the water jacket with a new gasket. Any recommendation to help prevent the minor water leaks from the bolts? Posted on: 2017/12/21 7:16

As far as i know these r not available. U can find a copper washer but there hard. Ive been using these sealant washers 93783A029 from McMaster Carr (same OD as orig) www.mcmaster.com Posted on: 2017/12/21 10:18
